Membrane Filter All types



Microporous 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. 

PES
Polyethersulfone (PES) membranes are hydrophilic, low protein binding and stable in alkaline pH. Available in a 0.8µm 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 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. The hydrophobic nature of the membrane also has applications for air and gas sterilization. Hydrophilic PTFE can be used to filter aqueous and organic mixed liquids.

Mixed Cellulose Ester (MCE)
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 

Hydrophilic PVDF Used in applications such as multi-plexed bead-based assays, the filtration of dilute protein samples, cold and hot water for injection (WFI), chemicals, aggressive solvents and sanitizing agents. Not suitable for acetone, DMSO, or based>6N.
