PCTE (Polycarbonate) Membrane

POLYCARBONATE (PCTE) MEMBRANE PCTE (Polycarbonate) membrane is made from a thin, microporous polycarbonate film material. It is ideally suited for use in blood assays and high-purity and general filtration applications. FEATURES AND BENEFITS

• Absolute pore size and density • Smooth, thin, glass-like surface • Superior strength • Low extractables • Low protein binding • Negligible absorption/adsorption • Available as hydrophilic or hydrophobic

APPLICATIONS

• General filtration • Removal of red blood cells from plasma • Flow control of reagents through assay • Precise filtration and prefiltration

PRECISE PORE SIZE AND DENSITY Sterlitech PCTE membrane is produced through a two-step, proprietary manufacturing process that employs high quality standards. This unique process allows for increased control over pore size and density to ensure the physical properties of each membrane precisely fit your specifications. In the first step, thin polycarbonate film is exposed to collimated, charged particles from a nuclear pile. As these particles pass through the polycarbonate material, they leave sensitized tracks. In the second step, the polymer tracks are dissolved with an etching solution to form cylindrical pores. Varying the temperature and strength of the etching solution, and the exposure time to it, produces precisely controlled pore sizes. The resulting membrane is a thin, translucent and microporous polycarbonate film with a smooth, flat surface. All particles larger than the pore size are captured on its surface. It is ideal for use when collecting samples for blood assays or for high-purity and general filtration.

PETE (Polyester) Membrane

POLYESTER (PETE) MEMBRANE Sterlitech PETE Polyester Membranes are made from a thin, microporous, hydrophilic polyester film with a high degree of solvent resistance. It is ideal for use in blood assays or general filtration where chemically aggressive solvents may be used. FEATURES AND BENEFITS

• Available as hydrophilic • High range of chemical compatibility • Smooth, thin, glass-like surface • Precise pore size and density • Low extractables • Low protein binding • Negligible absorption/adsorption

APPLICATIONS

• General filtration • Removal of red blood cells from plasma • Flow control of reagents through assay • Precise filtration and prefiltration

PRODUCT UNIFORMITY AND HIGH SENSITIVITY MAXIMUM PERFORMANCE Sterlitech Polyester membrane is produced through a two-step proprietary manufacturing process that employs high quality standards throughout production. This unique process allows for increased control over pore size and pore density to ensure the physical properties of each membrane precisely fit customer specifications. In the first step, thin polyester film is exposed to collimated, charged particles from a nuclear reactor. As these particles pass through the polyester material, they leave sensitized tracks. In the second step, the polymer tracks are dissolved with an etching solution to form cylindrical pores. Varying the temperature and strength of the etching solution, and the exposure time to it, produces precisely controlled pore sizes. The resulting membrane is a thin, translucent, microporous polyester film with a smooth, flat surface containing pores of controlled diameter and number. The membrane has better solvent resistance than polycarbonate and captures all particles smaller that the precisely controlled pore size on its

surface. Sterlitech PETE is ideal for use when analyzing blood samples or particle analysis by microscopy.

Polypropylene Membrane Filters

POLYPROPYLENE MEMBRANE FILTERS AND PRE-FILTERS POLYPROPYLENE MEMBRANE FILTERS

Sterlitech polypropylene membrane filters are composed of pure polypropylene with absolute pore size ratings. These filters offer broad chemical compatibility allowing its use with aqueous and organic solvent samples.

The polypropylene filter has extremely low extractable levels designed to provide accurate, consistent analysis results for sensitive ion chromatography applications while prolonging column life. Sterlitech polypropylene filter is the preferred filter membrane for HPLC applications where the detection levels are below 230 nm.

The filters also exhibit negligible protein binding which, is essential for maximum sample recovery of critical, small volume protein samples. Sterlitech filters are available in 0.1, 0.22 and 0.45-micron pore sizes in a wide range of disc diameters.

FEATURES AND BENEFITS

Broad Chemical Compatibiliy Hydrophobic HPLC applications – detection levels < 230nm

APPLICATIONS

• Aqueous and organic solvent filtration

• HPLC sample preparation requiring low detection levels

• Ion chromatography • Total digest for heavy metals

Chemically and biologically inert, Sterlitech polypropylene pre-filters are recommended for pre-filtering acids, aqueous and most solvent solutions. They are also used as a final filter for noncritical filtrations to reduce costs.

Polypropylene pre-filters are available in 0.2, 0.45 and 1.2 micron nominal pore sizes.

Features and Benefits:

• Chemically and biologically inert • Low fiber release • More defined pore size and greater retention efficiency than glass pre-

filters

PTFE UNLAMINATED FILTER MEMBRANES

Sterlitech Unlaminated Teflon® membrane consists of a pure PTFE tortuous pore structure. The larger pore sizes are thicker for easy handling. The filters are chemically and biologically inert, stable up to 260°C (500°F) and will withstand most concentrated acids and bases.

The unlaminated filters are compatible with strong acids, aggressive solvents and high temperatures, which can soften the polypropylene support of laminated Sterlitech PTFE. These filters are ideal for applications requiring stringent temperatures or chemicals without adding particulates to the filtrate.

In addition, since Sterlitech PTFE membrane filters are naturally hydrophobic, they are very useful for aerosol sampling, air venting, and gas filtration, especially in environments also containing water vapor. For filtering aqueous solutions, PTFE requires pre-wetting with alcohol to establish flow with reasonable pressure differentials.

Available in cut disc form, in 0.22, 5.0, and 10 micron absolute pore sizes.

Thickness: 0.22 µm is 50 µm thick 5.0 µm and 10.0 µm are 250 µm thick


• Naturally highly hydrophobic • Compatible with high temperatures, strong acids and aggressive

solutions • Chemically and biologically inert • Superior chemical resistance • USP XXI Class VI approved • Can withstand high temperatures

APPLICATIONS

STERLITECH NYLON FILTER CAPSULES Nylon Capsule Filters have a unique polyester and polypropylene construction for enhanced reliability and usefulness. Polyester housing and support layers ensure and maintain capsule integrity, while a nylon prefilter membrane layer over a final membrane layer significantly enhances filter life. They are suitable for a broad range of applications, meeting worldwide demand for functionality in chemical, beverage, and water processing. FEATURES AND BENEFITS

• Naturally Hydrophilic Nylon Membrane (Absolute Rated)

• Small Disposable Capsule • Ease of Scale-up • Low Filter Extractables

APPLICATIONS

• Solvents • Fine Chemicals • Ink Jets • Process Water • Beverages • Cosmetics • Parts Cleaning • Electronics

• Pharmaceuticals • Biologics • Dyes • Lacquers

PRODUCT DESCRIPTION Sterlitech Nylon filter capsules are highly retentive naturally hydrophilic Nylon membrane filters that have been specially designed for critical gas and liquid applications. The Nylon membrane in an all-polypropylene construction provides excellent chemical compatibility and superior flow per surface area as compared to other membrane capsules. No adhesives, binders, or surfactants are used in the manufacturing process and all capsules are rinsed with high purity water to reduce extractables and downtime.

The naturally hydrophilic Nylon membrane does not require pre-wetting with IPA and flushing with DI water thereby eliminating a potential source of contamination and hazardous waste. In addition, the hydrophilic membrane reduces the potential for bubble formation by not de-wetting in outgassing fluids unlike hydrophobic filters such as polypropylene. All filter capsules are 100% integrity tested to ensure filter performance each and every time out of the package. Sterlitech Nylon filter capsules are well suited for critical applications where superior flow and particle removal efficiency at 0.1, 0.2, 0.45, and 0.65 micron is required.
