Product description – Omnitek U-VIsc series Compact, high throughput automated viscometer

The Omnitek U-VIsc is the next generation of

completely automated viscometry systems. The system combines several unique features, making it the instrument of choice in many applications, ranging from QC to R&D to used oil analysis. While offering full compliance with ASTM D445/446, the specially designed viscometer tubes cover a 100-fold range, e.g. from 1 to 100 mm2/s. The tubes are based on the well-known and proven Ubbelohde design, but only require 8-10 ml. of sample and approx. 10-12 ml. of solvent for cleaning. Available with single or dual solvent cleaning, the instrument measures kinematic viscosity in Newtonian fluids like lubricants, fuels or dissolved plastics between 0.5 and 10,000 mm2/s. Omnitek U-VIsc 220 is fitted with two independent baths, each containing 2 viscometer tubes. This allows for choice of 2 equal viscometers for high throughput, or 2 different ones, allowing for high versatility. Sophisticated temperature control ensures that measurements are carried out well within limits specified by ASTM D445. Each bath features a 32-position sampling tray (16 samples per tube), allowing completely unattended operation. Depending on the viscosity of the sample, the instrument can process up to 40 measurements per hour, satisfying even the needs of high volume labs running several hundred samples per day. Samples can be introduced via either suction or pressure. The latter avoids evaporation of sample, which can be a point of concern in some dilute viscosity applications. Viscometers are easily exchanged in minutes instead of hours, minimizing downtime. All surfaces of the viscometer, including the outside bottom, which is in contact with the sample, are thoroughly cleaned and dried using solvents and air. Omnitek U-VIsc requires a PC for operation (not included) but can also be controlled through the advanced color touch screen interface (200 series only). For data collection, storage, calculations and reporting, an advanced PC application is provided with the instrument, which can gather data from up to 4 instruments simultaneously.

Safety Safety was a primary concern throughout the design of the U-VIsc series. Many precautions have been taken. Every movement of the sample carrousel, cylinders and sample table is verified by accurate sensors. Additionally, bath over-temperature cut-offs, bath level detection and emergency stop safeties have been implemented. U-VIsc is built from highest standards of mechanical parts. It has ultimate chemical resistance towards most common used fluids and solvents like petroleum ether, kerosene, toluene, acetone, MEK, phenol, cresol, o-chlorophenol, chlorobenzene, trichloroacetic acid, 90% formic acid and glacial acetic acid.

U-VIsc series site requirements U-VIsc 100/200 is a bench-top instrument that requires little counter space for operation. There are several things that need to be taken into account to facilitate its operation and maintenance. Instrument should be placed on a level surface which is free from vibration and located close to the utilities required for operation such as power, compressed air (5 bar, free of particles, oil and dust), solvent supply, fluid waste disposal and venting. U-VIsc 100/200 often fit on standard laboratory work benches, however 5 cm clearance is required to enable connection to utilities at the back of the instrument. If required, a specially designed pedestal base is available. An air-conditioned room is recommended for optimal temperature stability of the thermostatic bath. It is also good practice not to place the instrument in front of a window or door where the sun or drafts may cause temperature changes.





Specification Sheet

Optional accessories & upgrades Following items are optional accessories and upgrades to the instrument.

Dual solvent cleaning A suitable solvent used for cleaning should have the following 2 main characteristics:

It should be able to dissolve the sample that was tested, i.e. clean the tube

It should evaporate quickly enough at the test temperature so that the tube is dry after cleaning

If the solvent used does have the ability to dissolve the sample, but does not evaporate quickly enough, a second solvent can be used to clean out the first solvent, as well as dry the tube. Usually, low boiling solvents are used for this purpose, such as Acetone or MEK. All fittings and valves on the system are fully chemically resistant and allow for the use of solvents like Petroleum ether, Heptane, Toluene, Acetone or MEK.

Sample pre-heater All U-VIsc versions can be equipped with a sample pre-heater unit suitable to heat up fluids and solids from ambient up to 110 °C (controllable). Sample pre-heating is applicable to every tube, so ultimately a U-VIsc 220 may be equipped with 4 sample pre-heaters.

High temperature option Several applications like Polyethylene solutions, Waxes or Bitumen require elevated measurement temperatures. All U-VIsc variants can be built with special components capable running up to 150 °C. Suitable HT oil will be provided.

Cooling Spiral & cooling circulator For measurements close to ambient (± 8 °C), an additional cooling circulator is required to create sufficient offset for the temperature control unit. Both baths needs to be fitted with a cooling spiral, to which an external cooling circulator can be easily connected. Complete with tubing and fittings. Cooling spiral and cooling circulator will be supplied separately on request.

Touch screen option (for U-VIsc 100 series) The 200 series has an integrated touch screen but for the 100 series, this is an optional upgrade. The instrument can be fully operated through the PC interface so it is not required for daily operation, but the touch screen provides a more direct means of feedback to the operator.

Compressor Omnitek U-VIsc systems operate on clean 5-6 bar compressed air. If not available on-site a stand-alone version with @ approx. 100 l/min capacity can be provided.

Pedestal base Pedestal base can be supplied from Omnitek for floor-standing installation.

PC & Printer PC can be supplied locally or from Omnitek. Omnitek supplies a new generation laptop. Minimum operation software should be Windows 7. Any kind of printer can be used if instrument is connected to a PC by software. Printer can be supplied locally or from Omnitek. Omnitek supplies the latest model laser printer.

U-VIsc series software U-VIsc utilizes advanced and easy to use software. One PC can control up to 4 different systems (1 COM-port required for each instrument). Data can be exchanged with a LIMS via RS-232 or wire-less. The instrument can be operated in its entirety through the PC interface. Sample ID's can be loaded and sample queues can be started, halted or temporarily suspended. Results are automatically stored in the internal database and optionally also on any external drive or network folder. During a run several kind of information is shown like measured flow times, average, spread and calibration / viscosity result. Also actual status like filling, cleaning, etc is shown for every unit involved. Measured flow times are presented in left or right column, depending whether upper or lower measuring bulb is used for testing. Sample queue is permanently present and can be edited any time without interrupting running samples.

Viscometer tube selection The instrument utilizes up to 4 modified Ubbelohde viscometer-tubes, 1 or 2 in each bath. Using thermal sensors, tubes are suitable for both opaque and transparent, non-conductive samples. Using optical sensors, tubes are suitable for transparent and/or conductive fluids. Prior to measurement, the sample is drawn up into the viscometer tube and then allowed to warm up to the test temperature. Then, the sample flows down under gravity and the time between the sensors is measured. Two different tube concepts are available:

100-fold 3 sensor tubes These tubes have 3 sensors and 2 different measuring trajectories: the lower trajectory is used for high viscosity samples and the upper trajectory for lower viscosity samples. During sampling, the system measures the time it takes the sample to travel from the lower sensor to the middle sensor, thereby establishing the approximate viscosity. If the viscosity is high, the sample will be measured





Specification Sheet

in the bottom trajectory, if it is low, it will be pulled up to the upper sensor and measured in the upper trajectory. The 3 sensor tubes thus have a very wide measuring range, approximately 100-fold, combined with fast flow times. They do require more sample volume (up to 16 ml) and solvent for cleaning.

10-fold 2 sensor tubes For users who only measure a narrow range of products, the 100-fold tubes as described above are not required. They can suffice with the 2-sensor tubes, which have approximately a 10-fold measuring range. These tubes allow for even faster measurement, require less sample (approx. 8 ml) and solvent for cleaning.
