These Corning® syringe filters have polypropylene copolymer housings, female Luer lock inlets and male Luer slip outlets. PTFE membranes provide the best chemical resistance Manufactured in accordance with ISO 9001 standards
Our PTFE membrane cartridge filter is manufactured by the precise and quality process, applicable to the gas, air, chemical filtering of the microchip LCD manufacturing process of high tech industry, the manufacturing process of food and pharmaceutical intermediates.
Corning Incorporated is the world leader in specialty glass and ceramics. Drawing on more than 150 years of materials science and process engineering knowledge, Corning creates and makes keystone components that enable high-technology systems for consumer electronics, mobile emissions control, telecommunications and life sciences.
The filter replacement is necessary, if drawing efficiency deterioration is observed. The direct reason may be a dirty filter after a long period of use. In order to replace the filter: • Remove the pipet. • Unscrew the nose piece (Figure 4.1). • Remove the membrane filter (Figure 4.1) and the pipet holder (Figure 4.2).
These Corning syringe filters have polypropylene copolymer housings, hose barb inlets and hose barb outlets. • PTFE membranes provide the best chemical resistance. • These naturally hydrophobic membranes can be used for venting applications or filtering gases. • 100% integrity tested, sterile and certified nonpyrogenic and noncytotoxic.
Filter membranes with higher porosities also have more surface area for binding or adsorption, the adhesion of particulates from a gas, liquid, or dissolved solid to the membrane surface. Types of membrane filter materials include polytetrafluoroethylene (PTFE), Porex® PTFE, cellulose acetate, nitrocellulose, and nylon.
Pore size and membrane type is printed on every syringe filter. Sterile filters are individually blister-wrapped in cases of 50, nonsterile in cases of 50. Compliance. Manufactured to ISO 9002 and GMP standards, and 100% integrity tested.
The collagen-coated PTFE membrane is fragile and requires careful handling during removal. A wetted cellulosic membrane filter should be placed in direct contact with the underside of the Transwell insert membrane before it is cut out with a scalpel. The wetted, more rigid, cellulosic filter will serve as a support for the collagen-coated membrane.
Corning syringe filters are 100% integrity tested and are certified nonpyrogenic and noncytotoxic and are manufacturered in accordance with ISO 9002 standards. A variety of membranes are available to meet your needs.
Description. For tissue culture and HPLC applications. Acrylic housing. A variety of membranes are available to meet your needs: Polyethersulfone (PES) – low protein binding and faster flow rates; surfactant-free cellulose acetate (SFCA) – lowest protein binding; polytetrafluorethylene (PTFE) – chemical resistance; regenerated cellulose (RC) – best choice for DMSO compatibility; Nylon
LC = Limited Compatibility (Membrane may swell and shrink) IC = Incompatible (Not Recommended) ND = No Compatibility Data Currently Available Choose a filter or membrane based on: 1. Chemical compatibility of the membrane and housing with your sample matrix 2. Size and amount of particulates in the sample 3.
