"Batch Pressure Filter Cloth"

Supplier: Cytiva

Membranes are made from pure cellulose acetate, making them ideal for biological and clinical analysis, sterility tests, and scintillation measurements. Filters exhibit very low protein binding capacity and are hydrophilic, making them suitable for aqueous and alcoholic media. The cellulose acetate membranes have improved solvent resistance, particularly to low molecular weight alcohols, and increased heat resistance. The membrane filters exhibit high physical strength and can be used up to 180°C (356°F), making them suitable for hot gases and allowing them to be sterilized by all methods without sacrificing the integrity of the membrane.

Acrodisc™ syringe filters with Supor™ membrane deliver high flow rates and low protein binding.

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.

Adding a syringe filtration step prior to injection not only helps to ensure more consistent and reliable results; it also helps protect delicate instruments and prolongs column life. Available in sizes and membrane types to meet any application need, Thermo Scientific™ Target2™ Syringe Filters provide cleaner sample extracts by removing interfering materials and fine particles down to the rated pore size. Target2 Nylon Syringe Filters are a good choice for most general laboratory filtration, as well as filtration of most HPLC samples.

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: Cytiva

Whatman™ Uniflo™ syringe filters are well suited for rapid, routine syringe filtration of small volume samples up to 100 ml in laboratory sample preparation.

Supplier: Cytiva

For use in cell culture and other sensitive biological research.

Supplier: Cytiva

These 13mm and 25mm filters are optimized to provide the most consistent results when analyzing ionic species using IC (ion chromatography). Certified for low conductivity detectable extractables. Also excellent for filtration of dissolution samples. Supor® (hydrophilic polyethersulfone) membrane exhibits very low drug and protein adsorption. Polypropylene housing. Effective filtration area: 3.9cm² (25mm) or 1.0cm² (13mm). Recommended sample volume: \<150mL (25mm) or \<10mL (13mm). Typical hold-up volume: 125µL (25mm) or \<10µL (13mm).
