Vacuum filtration is driven by negative pressure (from a vacuum pump, for example) applied downstream of the filter holder. The retentate on the filter's surface or the fluid filtrate can be collected for further analysis. Vacuum filtration is used primarily in microbiological and laboratory procedures involving the collection of a particulate
The Autofil™ laboratory filtration system is a disposable, sterile, vacuum operated bottle-top filter system used for the preparation of buffers, tissue culture media, microbiological media and other biological fluids. Autofil™ filters are available either as a complete system or as a stand-alone bottle-top filter funnel. Read More.

PTFE membrane filters have an excellent chemical compatibility (pH 1 to 14), so that they are also used for the filtration of solvents and acids, to which other filter types are not resistant. Moreover they can be used to filter aqueous solutions as well, but because of their hydrophobic characteristics, they must be pre-wetted with ethanol or methanol before the filtration of aqueous media
PTFE filter membrane, 47 mm diameter, 0.20 µm pore size, 100/pk 5191-4339 Nylon (polyamide) • Hydrophilic membrane suitable for particle removement of alkaline solutions and organic solvents • Nonsterile PTFE (polytetrafluorethylene) resistance and pH
Membrane Filters Membrane filters are surface filters used to remove particulate or collect microorganism for analysis from solutions, on and near the surface of the filter matrix by mechanical means. Our wide range of membrane materials (PTFE, regenerated
ptfe membrane are prized for several reasons. Key among them is that they dull weathering effects. They provide temporary protection if a shingle has come off and protect the deck from exposure while the roof is being repaired. They are also cost-effective, as they are more affordable than other roofing materials.
0.10/0.22 micron PTFE filter membrane for laboratory vacuum filter system Ready to Ship $46.70-$52.90 / Pack 10 Packs (Min. Order) $19.54 /Pack Hawach Scientific Co., Ltd. CN 3 YRS
Pre-assembled and ready to use, these caps are supplied with 1mm thick, Silicone/PTFE septa inserted in the caps. Excellent for GC or Headspace analysis. Use these caps instead of the standard magnetic crimp caps and avoid the difficulty in crimping and decrimping due to the hard metal used in the crimp cap.
MS ® venting filter is also named vacuum protection filter or gas line filter. Filter units with hydrophobic PTFE membrane are ideal for sterilizing gases, venting sterile containers, and sterilizing or clarifying organic solutions and protect your laboratory.
Filter Microplates. Aijiren filtration microplates incorporate most filtration media types, including but not limited to glass fiber, polyethylene, polypropylene, nylon, polyethersulphone (PES), and polyvinylidene fluoride (PVDF). They are available in 4-well configurations (140 µL to 15 mL/well) and are suitable for vacuum and positive pressure
