Description

Membrane Filter

The microporous membrane filter is mainly used for the filtration of mobile phase and samples during the chromatographic analysis, especially for preventing chromatographic column and infusion pump line system and sample valve from pollution. They are widely used for gravimetric analysis, microanalysis, colloid separation and sterility test. The filer membrane made of different materials, such as polyetherdsulfone (PES), nylon6, Nylon66 MCE and polytetrafluoroethylene (PTFE), PVDF etc. can be provided.

Nylon66

High quality nylon66 membranes are suitable for filtering aqueous solutions and most organic solvents. The membranes are suitable for use with a wide range of biological preparations and can be used where other membranes are unsuitable or difficult to use.

Nylon66 membranes are hydrophilic, eliminating the need for wetting agents that could be extracted when filtering aqueous solutions. The membranes are flexible, durable and tear resistant, and can be autoclaved at 121oC. This kind of membrane is imported from England.

Applications:
* Filtration of aqueous and organic mobile phases
* Vacuum degassing
Filtration of tissue culture media, microbiological media, buffers and solutions

PES

Our polyethersulfone (PES) membranes are hydrophilic, low protein binding and stable in alkaline pH. Available in a 0.8¦Ìm pore size, the PES membrane is recommended for aqueous applications and for biological samples. They are also an alternative choice for users requiring a filter that exhibits extremely low protein binding characteristics. This kind of membrane is imported from MEMBRANA company in Germany.

PTFE
PTFE membranes are particularly suitable for preparing samples for HPLC analysis. The hydrophobic nature of the membrane also has applications for air and gas sterilization. The membrane is laminated onto a non-woven polypropylene support web for improved strength and handling and can be used at temperatures up to 150oC.

PTFE is the membrane of choice for use with the aggressive solvents, liquids and gases that can attack other membranes. It is resistant to most acids, alkalis and solvents.

Applications:

One of the major applications for the PTFE filter is the clarification of corrosives, solvents and aggressive fluids. This includes the important requirement in HPLC analysis for sample filtration where any solid particles can cause permanent damage to the column. The 0.45¦Ìm pore size is normally used.

Mixed Cellulose Ester (MCE)

Our MCE membrane filters are modified to offer researchers the lowest binding filters available. Due to the extremely low binding characteristics, these filters provide higher throughputs than competitive offerings and reduce filter changes when filtering proteinaceous solutions.

Because of their unique strength and extremely low binding characteristics, Jinteng MCE membranes are ideal for protein and enzyme filtrations, tissue culture media sterilization, cold sterilization, biological fluid filtration and other filtration applications where maximum recovery of proteins is critical.

Features and Benefits:
* Lowest binding material available
* Hydrophilic
* High throughput
* Strength and dimension stability
* Uniform pore structure

Applications:
* Protein and enzyme filtration, sterilization
* Biological fluid filtration sterilization
* Tissue culture media sterilization
* Diagnostic cytology
* Receptor binding studies
* Enhanced recovery of fastidious gram positive organisms
