"Membranes for sterile filtration"

Supplier: Cytiva

Whatman Anotop sterile syringe filters from Cytiva contain an inorganic Anopore membrane. The low protein binding exhibited by this sterile membrane filter make it well suited for biological filtration.

Supplier: Cytiva

Ideal for biological, pharmaceutical, and sterilizing filtration requirements. Supor® hydrophilic polyethersulfone membranes offer higher fluid flow rates, lower protein binding, lower extractables, and greater strength than other cellulosic (acetate, nitrate) membranes. Provide some of the highest water flow rates and fluid filtration capacities of any sterilizing grade membrane filter. Nonsterile, except for 28147-979, which is gamma-irradiated.

Supplier: Cytiva

These 25mm filters are ideal for scale up. Filters feature a polypropylene housing and a choice of four membrane types to assure compatibility with a wide range of fluids. Choose Supor® (hydrophilic polyethersulfone), Ultipor® (amphoteric Nylon N66), Fluorodyne® II (hydrophilic polyvinylidene fluoride), or Posidyne® (positively-charged Nylon N66) membrane. Filters are tested for bacterial retention to assure sterile filtrate and can be integrity tested by the water bubble point method. There is no need to change membrane materials during transition to pilot or full-scale production. Filters have a female Luer-lock inlet and a male slip Luer outlet. Sterilized by gamma irradiation.

Supplier: Thermo Scientific

PVDF (polyvinylidene difluoride) is a hydrophilic, solvent-resistant membrane with low levels of UV absorbing extractables. Housing manufactured from medical grade, virgin polypropylene. Low nonspecific binding. Use for HPLC sample filtration and general biological filtration. PVDF is also a low protein binding membrane. Enhanced female Luer-lock inlet; male Luer slip outlet. The 4mm filters can be used for volumes less than 2mL. The 0.2µm pore size filter can be used for “cold” sterilization.

Supplier: VWR International

Systems for vacuum filtration of aqueous solutions including cell culture media, buffers, or other biological fluids.

Supplier: Cytiva

Designed both for prefiltration of particulate liquids (such as serum) prior to sterilizing filtration, and removal of debris and particles from liquids not requiring sterilization.

Supplier: VWR International

Typical applications are clarification, sterile filtration, sample preparation and sterile venting.

Supplier: Corning

For filtration of liquids from 0.5mL–100mL. Available in 4, 15, 25, 26, and 50mm diameter filters. Available in polyethersulfone and surfactant-free cellulose acetate for cell culture applications requiring low protein binding, and in fluoropolymer resin PTFE resin, regenerated cellulose, and nylon for HPLC applications requiring a broad range of chemical compatibility. Redesigned 26mm filter increases effective filtration area resulting in faster flow rates and higher throughput. 50mm fluoropolymer resin vent filters help prevent aggressive solvents from damaging vacuum lines and pumps.

Supplier: Thermo Fisher Scientific

For easy, fast, sterile filtration of 150 to 1000 ml volumes.

Supplier: Thermo Fisher Scientific

Presterilized filter units with surfactant-free cellulose acetate membranes are ideal for proteinaceous solutions.

Supplier: Thermo Fisher Scientific

All of these filters come with an asymmetric polyethersulfone (PES) membranes.

Supplier: Cytiva

Whatman Polycap TC filtration capsules from Cytiva feature dual layer polyethersulfone (PES) membranes and provide efficient filtration for aqueous solutions.

Supplier: Thermo Fisher Scientific

For microbiological testing of water quality, food/beverages, raw material, sterility, and finished product quality. Use in vacuum manifolds and filter flasks.

Supplier: Cytiva

For filtration of tissue culture media, cleanup of difficult samples for analysis, filtration of colloidal material, and removal of mycoplasma.

Supplier: Corning

Vacuum filter systems available in four sizes: 150 ml; 250 ml; 500 ml and 1 L. Adapters are colour coded by membrane type for easy product identification: Polyethersulfone (PES) yellow; cellulose acetate (CA) orange; cellulose nitrate (CN) blue; nylon (NY) red.

Supplier: Thermo Fisher Scientific

Units are designed for applications requiring low extractables.
