2015/4/6 · Filter Sterilization Air and Liquid media. 2. Filter Sterilisation Filtration is used for the removal of microbes from solutions that cannot easily be treated in other fashions. Typically heat-sensitive compounds such as antibiotics and vitamins are filtered before addition to sterile cool media.
PTFE membrane is a thin, highly porous film that behaves as an absolute retentive membrane. Their inherently hydrophobic nature make PTFE membranes ideal for applications such as filtering gases, aqueous aerosols, protecting vacuum pumps, or sterile venting fermentation tanks. PTFE is inert.
Material: PTFE membrane (Collagen Coated PTFE) clear polystyrene plate flat bottom wells clear round wells Sterility: sterile Feature: lid plate format: 6 well Packaging: pack of 1 case of 24 Mfr.: Corning, 3491 Insert working Volume: 1.5 mL Membrane Diam
Corning® 1000 mL Vacuum Filter/Storage Bottle System, 0.22 µm Pore 54.5cm² PES Membrane, Sterile, 12/Case. Polyethersulfone (PES) membranes provide the fastest flow rates, the lowest protein binding and low extractables and are best for filtering cell culture media.
These Corning® syringe filters have polypropylene copolymer housings, female Luer lock inlets and male Luer slip outlets. Nylon (NY) membranes are naturally hydrophilic, surfactant-free and offer the lowest extractables 100% integrity tested, sterile and nonpyrogenic and noncytotoxic Manufactured in accordance with ISO 9001 standards
2014/6/26 · Basically, if the filter can retain a minimum of 1 x 107 colony forming units (cfu) per cm2 of a challenge bacteria (usually B.diminuta5), then the filter is suitable to use for sterilization. Even with the contraction of the standard pore size for sterilization, it turns out that simple size selection is not a sufficient method to fully contain all particles.
Membrane filter units are versatile tools used to test samples for microbial contamination. Many units are disposable, eliminating the cleaning and sterilization required with reusable funnels. The membrane filtration units can be installed in relatively small facilities that blend into the surrounding area and can be fully automated to significantly reduce the required amount of operator attention.
EMD Millipore is the brand of choice for sterile filters for everything from media preparation for your cell culture to sterilization of critical drug compounds. EMD Millipore Sterile Filtration Brochure (1.3 MB) Thermo Scientific Nalgene Rapid-Flow Filters Brochure. From the outside, bottle top Filters look alike.
film layers, Corning’s proprietary coating process results in a biologically stable collagen that covers every fibril of the filter matrix, thereby retaining the porosity of the membrane. Pore Sizes Selecting the correct pore size for experiments is also very impor
Nest syringe filters have pore size either 0.22µm or 0.45µm, and diameter 13mm or 25mm, with membrane materials either with PES or PVDF membranes. For sample volumes of 2mL to 100mL. Retention volume <115µL. Maximum operating temperature: 100 C
Designed for use on glass or polystyrene media bottles with 33 and 45mm neck sizes.
