Let there be light!A complete high-performance for photo-stability tests
04
Challenges for pharmaceutical
companies
Compulsory documentation of
these tests must be provided to the
authorities without exception, adding
an extra burden to pharmaceutical
company test laboratories. For the
new photo-stability tests, samples
must be exposed to a light amount
of 1.2 million Lux* hours, as well as
UV radiation of 200 Watt*hours/m2
in climatic chambers with ICH
illumination. But how can these
light values be proven safely and
objectively?
New options at BINDER for
light tests
The fundamental prerequisite for
reliable recording is met with the new
option of light integration and display
of the light values on the controller.
This includes the automatic lamp
shutoff (VIS and UV separately) when
the freely selectable dosage values
are reached.
Reliable recording of the light
values is ensured by the two spherical
light sensors developed exclusively
for BINDER, which with their direction
independent characteristics, function
more precisely than planar sensors.
Another important point for the
testing authorities is the APT-COM®
DataControlSystem software of
BINDER chambers, enabling light
values to be saved and documented
in a GLP/GMP compliant format.
Valid for all
international standards
All of this makes the KBF with ICH
illumination a high-performance
complete system solution for stability
and photo-stability tests in
accordance with all international
standards and ICH guidelines,
whether by Q1A or Q1B, as well
as conforming to the requirements
of the FDA or GLP/GMP.
BINDER enables users to document
the test conditions in every phase,
not simply selling the chamber, but
a complete solution consisting of the
chamber, software, documentation,
calibration/validation, and service.
BINDER KBF climatic
chamber with improved
ICH illumination
Overall, the sun is a blessing
for humanity, but it can be
very damaging to the shelf
life of medications or
pharmaceutical products.
The ICH guideline for
photo-stability testing to
ensure products maintain
their characteristics over
their period of use has been
obligatory since 1996.
BINDER has optimised the
KBF climatic chamber with
ICH-compliant illumination
to help pharmaceutical
companies meet this
mandate.

Measurement Technology for Temperature
A highly precise temperature measuring system is required as a working standard, especially
in the areas of quality assurance, calibration services and laboratories. The testo 735, via
the Pt100 probe input, achieves an accuracy of up to 0.05 °C in a measurement range from
-40...+300 °C (resolution of the probe of 0.001 °C) and is the ideal solution. An optional
ISO/DKD certificate, using a precise 5-point calibration over the entire measurement range is
available as supporting documentation.
In addition to the highly precise immersion-penetration Pt100 probe, two further thermocouple
probes (Type K/T) can be plugged into the instrument from a wide range of immersion, air
or surface probes for many different applications. Wireless measurement up to a distance of
20 m is possible from a further three probes increasing convenience and avoiding damage to
connecting wires that may jeopardise accurate results. The optional radio module for the testo
735 can be retrofitted at any time, as it is simply plugged into the battery compartment in the
back of the instrument. The testo 735 documents the measurement results either on site using
the handy testo report printer or on a PC with the convenient PC software. Two models are
available:
Covering a temperature range from -200...+1350 °C (depending on choice of probe), the testo
735 has logical easy-to-follow menus guiding users through functions such as timed and
multi-point mean calculation, differential temperature measurement and max/min value display.
A robust instrument housing takes the usual knocks and jars of a busy environment, and has
a large illuminated display positioned slightly set back in the housing for extra protection.
A carrying strap enables easy and safe transportation whilst magnets on the back ensure
secure attachment at the measuring location.
The testo 735 is also IP54 rated.
Assurance through precision
Highly precise temperature measurement with an accuracy of up to 0.05 °C!NEW
testo 735-1
Uses a “cyclic printing” function to print
measurement data at a rate from 1 minute
to 24 hours on the testo report printer
by infra-red interface.
As well as measurement readings, the date
and time are documented on the printout.
testo 735-2
Supplied with PC software as standard
for the presentation of data. Single
measurements or measurement series up
to 10,000 readings can be stored and then
presented either in graphic or tabular
format on a PC. The readings can be
transferred to the PC software online
or printed.

balances
The New Sartorius Extend SeriesThe difference is…the latest technology
http://uk.vwr.com
If you compare the specifications of many lab balances on paper, they all look the same –
if you’ve seen one, you’ve seen them all. But in the real world, there is more to a lab
balance than just its technical specifications.
The new Sartorius Extend series has been specially designed for effective and reliable weighing in daily lab routines.
This is where more powerful technology and application-orientated operation and features make all the difference.
Reliable weighing results, all of the time – even under less than ideal ambient conditions, thanks to the Extend’s
highly sophisticated digital compensation algorithms.
Sartorius utilise 21st century technology, such as our unique robotically etched monolithic weigh cell, which ensures
long-term, high accuracy and minimizes the effects of temperature drift. It provides the legendary dependability that
users the world over have come to appreciate in a genuine Sartorius lab balance. Also, the novel housing finish of the
Extend series is made to withstand many aggressive solvents, such as acetone and ethanol.
The Extend series features the latest powerful microprocessor technology, shortening the response times for faster
results than most basic or standard level balances.
A built-in, motorized calibration weight is standard in all precision balances with the CW suffix and in all analytical
balances. This feature ensures maximum weighing accuracy and operating convenience.
• Fast cleaning and rugged
design: The side doors, top
sliding door and all stainless
steel parts of the analytical
draft shield chamber are easy
to remove for convenient and
thorough cleaning.
• An optional adapter cable
enables you to connect a
device, such as a computer, to
the USB interface port. Plus,
an RS-232C port is standard
on all Extend balances.
• Whenever you need ISO/GLP
compliant printouts of raw
data and/or calibration and
adjustment data, the Sartorius
Extend balance will generate
them – at the touch of a key
when connected to a data
printer, the YDP03-0CE.
• User-friendly operation:
Short, plain-English text
prompts and cursor keys for
navigation make it simple for
you to configure the balance
to meet your individual
requirements.
• The level indicator is
positioned conveniently right
next to the display so that
checking whether the balance
is level becomes “second
nature” to the operator.
What’s more, all keys feature
positive click action.

The most complete and accurate line of microbial air monitoring systems available
microbial air samplers
Earliest microbial air samplers
trapped particles by centrifugal
force on special media strips. This
methodology had a tendency to
overestimate total counts. Today
the most effective methods are
sieve impaction systems based on
the Anderson impaction principle.
Such systems achieve much higher
flow rates enabling capture of
particles as small as 1 micron in
diameter and significantly reduce
the sample collection time.
The Merck MAS-100® Microbial
Air Monitoring Systems are the
most accurate examples of this
sample collection method. Air is
aspirated through a perforated lid
with 400 holes, impacting growth
media in a standard 90 mm petri
dish or 60 mm contact plate.
A state-of-the-art mass flow
sensor, in all models except
MAS-100 Eco®, assures a
constant air flow rate (real time)
of 100 L/min during
sample collection and automatically
adjusts for variations in media fill
levels and individual perforated
lids as well as air density.
ReferencesAnderson, A. A. (1958) “New Sampler for the collection, sizing and enumeration ofviable airborne particles.“ Journal of Bacteriology, Vol 76, pp. 471-484.Meier, R., Zingre, H. (2000) “Qualification of air sampler systems: The MAS-100®“Swiss Pharma 22, No. 1-2, pp. 15-21Feller, W., “An Introduction to ProbabilityTheory and its applications" John Wiley and Sons Inc., New York, 1950“Microbial Evaluation of CleanroomEnvironments“ U.S. Pharmocopiea 27,NF 23, General Chapters <1116>, 2004
MAS-100® / MAS-100 Ex®
Both these portable air samplers were initially designed for use in cleanrooms and do
not produce disturbance in a laminar flow environment. These compact devices are the
preferred choice for those demanding the highest quality in microbial air monitoring
with the highest airflow accuracy of ±2.5%.
The MAS-100 Ex® is approved for use in explosion risk areas, in accordance with
SN-SEV (NIN) for zone 2.
MAS-100 Eco®
This smaller, inexpensive lightweight unit is great for the cleanroom but also air
monitoring in production areas, e.g food and beverage. The unit has many of the same
features as the standard MAS-100® without the mass flow sensor. The handle doubles
as a stand and an optional tripod adapter attaches to the handle for fixed applications.
MAS-100 CG Ex®
The MAS-100 CG Ex® system enables quick, easy and accurate testing of compressed
gases for microbial contamination and is the only sampler approved for use in zone
2 explosion hazard areas. Calibrated with compressed air, the unique mass flow sensor
technology means only a mathematical correction factor is required to sample other
gases. (Pre-programmed for nitrogen, carbon dioxide and argon gas).
MAS-100 ISO®
Meets the most rigorous demands for efficient air monitoring of the microbiological
cleanliness in isolators and cleanrooms. The system consists of a control unit, aspiration
unit and a wall mounted sampling head that can be integrated into standard sterilisation
protocols thanks to an isolating double valve unit. Besides this sampling head no other
electronic or mechanical components are installed in the critically controlled zone.
Each control unit can run 4 sampling heads and in a BUS-system, up to 40 sampling
heads at the same time.
Five different versions of MAS-100® microbial air samplers are available
for different applications; each complies with the guidelines as specified
in ISO14698-1.

Sample Preparation without heavy metal contamination
The objectives of the new directives
are the environmentally safe
disposal of electrical and electronic
devices (WEEE) and the restriction
of the use of certain hazardous
substances in these devices (RoHS).
Every manufacturer, seller, recycler
and disposer of such products is
affected by the new regulations
and is required to demonstrate by
analytical determination that the
directives are being observed.
Electrical and electronic waste is
usually a heterogeneous mixture of
metal, ceramics, plastics and
composites, so neutral to analysis
sample preparation can be a problem.
Careful selection of effective
laboratory mills is critical as only a
truly homogeneous sample can
guarantee accurate results.
RETSCH Mills are ideal for grinding
without heavy metal contamination.

KINEMATICA – Finest Swiss Made Homogenisers
An example of an advanced sample
preparation unit
When the quantity of samples to be processed is
increasing and the time to do the preparation is
decreasing, but the quality and reproducibility of the
samples must be guaranteed you need an homogeniser
you can rely on. The multiple homogeniser system
POLYTRON® PT 3100 Quattro in combination with the
famous “W” shredder design is such an indispensable
tool.
Application example
The samples used for pesticide and herbicide residue
analysis vary immensely from all types of plant material
such as cereal grains, beans and straw to animal tissue,
such as meat or fat, etc. This material, which is
sometimes deep-frozen, must be dispersed in water,
acetone or methanol before analysis; according to GLP
standardised methods complying with legal guidelines.
The preparation of hard and brittle, sometimes tough
and fibrous samples is often difficult and time-consuming
work. Deep-frozen cereal grain, or, for example, broad
beans are extremely hard and abrasive; the connective
tissue from meat on the other hand is very fibrous and
tough. One disadvantage of standard dispersing
instruments is that hard particles get caught in the teeth
of the stator, and long-fibrous, vegetable and animal
tissue catch on to the teeth of the rotor. This stops
processing and consumes the sample whilst leaving the
tool virtually impossible to clean.
The “W” design of the POLYTRON PT3100 Quattro
generator has no surfaces with parallel faces; the teeth
get thinner towards the end. Coarser particles are,
therefore, not jammed in the stator teeth but thrown
outwards by the turbulence of the rotor and thus
reprocessed. In order to minimise abrasion caused by
hard particles, the rotor and stator of the dispersing
tool are coated and hard metal plain bearings are
used in the generator. These modifications increase
the life span considerably.
A large amount of mechanical force is required for
efficient preparation of the sample. The PT3100 and
PT6100 have powerful drives for higher rotational
speeds that reduce processing time. Best of all the
homogeniser can be cleaned quickly and simply
under the tap without the scrubbing
and scraping out required by other
models. The final result – good
quality samples – fast!
When it comes to homogenising you can rely on 60 years of experience to be sure to get the expert
solution. KINEMATICA works closely together with its world wide partners and customers to constantly
improve and speed up the sample preparation work.
POLYTRON® PT 3100 Quattro
Special features: four samples
can be processed simultaneously.
The special geometry of the
dispersing aggregate prevents
jamming of the stator.
The bearing system is designed
to be very durable, the coating
of the rotor and stator increases
the life time three fold versus
standard 316L. The Easy Clean
design allows a fast cleaning.
POLYTRON® PT 2100 (budget version)
KINEMATICA offers a wide range of other homogenisers to meet your application needs and budgets.

the right tool
19http://uk.vwr.com
The right tool for the job
An important part of what can sometimes be very lengthy and complex
analytical procedures is the trust you place in your high purity analytical
grade chemicals and reagents. The key consideration must be that the
results obtained from different batches will be consistent and accurate.
Such confidence comes in part from the large number of tests performed
on every batch of material so you know that the purity of each product
conforms to the data specified on the label. However, when considering
whether the different brands of analytical reagents available have
specifications suitable to your application it’s important to compare the
number of parameters tested by the manufacturer, the ways the
measurements are performed and whether they represent maximum
permitted levels of impurities or merely typical analyses.
An increasing number of chemicals are now available which meet the
requirements of specific techniques and processes. Production of these
chemicals may involve additional purification and packaging steps, such as
distillation and filling under nitrogen, to ensure that the reagents meet and
retain their guaranteed high purity specifications. In many cases the choice
of container used is critical too; you would not normally store a reagent
with a guaranteed low level of sodium in a glass bottle where the metal is
likely to leach from the container walls. Some packaging is specialised, for
example, solvents stored in special HDPE (high density polyethylene) reduce
the risk of extractable plasticisers and give the advantage of being light-
weight and user-friendly.
At VWR, we believe in the philosophy of “the right product for the right
application”. The re-assurance that a reagent will be suitable for a
particular application comes from the analytical tests performed on the
product. For example, anhydrous solvents such as Merck’s Seccosolv have
exceptionally low levels of water for synthesis and analysis of moisture
sensitive substances. High purity HPLC solvents, Merck LiChrosolv and
Prepsolv have specifications characterised by the high transmittances in
the UV spectrum and low levels of nonvolatile impurities. Ion pair reagents
should also be chosen on the basis of high UV transmittance and the absence
of insoluble impurities and redox traces. The use of GC (gas chromatography)
for residue and environmental analysis has its own particular reagent
requirements. Products such as Merck’s UniSolv and SupraSolv solvents are
tested to ensure absence of interfering signals when measuring with flame
ionisation (FID), electron capture (ECD) and MS- detectors.
For trace analytical procedures where contaminates are measured down in
the parts per billion (ppb) range it’s essential to use highly pure reagents
such as Merck’s Suprapur in sample digestion process to ensure acceptable
blank values. After all, there’s little point looking for trace amounts of an
element in a sample if the reagents used in the process have unacceptable
levels of that parameter as a contaminant. For ultra-trace analysis, in the
parts per trillion (ppt) range it’s necessary to use mineral acids from Merck’s
Ultrapur range. These acids, produced by sub-boiling distillation, are
supplied in bottles made from the inert fluoropolymer PFA and are
guaranteed to have less than 100 ppt contaminates.
Moving forward in today’s scientific world is a must; having confidence
in your analytical results by choosing “the right product for the right
application” reduces the requirement to repeat analyses and prevents
needless delays. Whether the material is a general purpose chemical or
an ultra pure trace analysis grade mineral acid it’s important that you
have complete confidence in the stated purity. At VWR we take that
trust very seriously and are proud to be exclusive distributors of the
world’s number one laboratory chemical brand – Merck.
