Glass fiber membrane filters are made of pure borosilicate and used to measure suspended solids. Some borosilicate fibers feature fine porosity and can tolerate high temperatures. PTFE membrane filters can have hydrophobic or hydrophilic characteristics. Hydrophobic PTFE membrane filters are used to sterilize gases and aggressive chemicals.
Nov 08, 2018 · Sterlitech offers a variety of hydrophobic membrane filters, including PTFE and polypropylene. Hydrophilic membrane filters. Sterlitech offers a broad variety of hydrophilic membrane disc and syringe filters, from inorganic silver and ceramic to polymeric nylon and polyethersulfone (PES). The applications for hydrophilic membranes are as varied
Filters are molded in the polypropylene housings, providing a reliable seal without the use of adhesives Female luer-lock inlet and male luer slip outlet Color coded by membrane type for easy identification, and membrane material and pore size are printed on the housing Available individually packed in peel-to-open paper/plastic blister packs Also available bulk packed in PVDF, PES, PTFE, and
Feb 11, 2020 · Teffil™ Teffil™ is a range of superior pleated PTFE membrane filters with PFA supports. These cartridge filters are suitable for use within a number of microelectronics, process and chemical applications. This chemically inert filter range offers the removal of fine particulate from 0.05-10 micron in challenging operating conditions.
PTFE membranes are naturally hydrophobic, and chemically resistant to all solvents, acids and bases. PTFE membranes do not impart any extractables to the filtrate. PTFE is an ideal membrane for transducer protectors, since it blocks water vapor and is also ideal for filtering and de-gassing chromatography solvents.
Teffil™ and Teffil™ HF are a range of superior pleated PTFE membrane filters with PFA supports. These cartridge filters are suitable for use within a number of microelectronics, process and chemical applications. This chemically inert filter range offers the removal of fine particulate from 0.05-10 micron in challenging operating conditions.
Nov 08, 2019 · A 260 °C (500 °F) continuous operating temperature filter bag, with ePTFE membrane on PTFE coated fiberglass woven backer for use in pulse jet style dust collectors. View as PDF (42.71 KB) Features and Benefits
Glass fibre depth filters are used where high flow rate and micron/submicron filtration is required. They are suitable for both air and liquid filtration. Select from binder-free filters for purity that is ideal for anaylitcal and gravimetric determination, or filters with binder for strength in long-duration, high-pressure or wet applications.
Fluorofil™ ePTFE Membrane Cartridge Filters. Fluorofil™ cartridges are manufactured using a highly hydrophobic ePTFE membrane. The enhanced ePTFE membrane offers exceptionally high gas flow rates at low pressure differentials. Fluorofil™ cartridges are recommended for sterile gas filtration and venting applications. The hydrophobic characteristics of the ePTFE membrane makes the Fluorofil™ filter cartridge particularly suitable for wet gas sterilising applications, such as fermenter
biological fluids and gases is usually done with 0.2 or 0.22 µm pore filter membranes. Clarification and prefiltration of solutions and solvents is best accomplished with 0.45 µm or larger filter membranes. Prefiltration to improve filter performance can also be accomplished by the use of glass fiber prefilters that can be purchased separately.
The addition of PTFE membrane to standard filter fabrics will on average lower initial permeability from 30-60 CFM to 5-15CFM (depending on the fabric substrate and type of PTFE membrane). Under normal conditions Baghouse.com PTFE membrane filters will operate at 0.5in pressure drop at a 6:1 air-to-cloth ratio.
Memtrex Pleated Membrane Filters. Memtrex™-FE Filters PTFE Membrane Teflon* PTFE membrane, ideal for the filtration of bulk chemical, ultrapure water and gases. Memtrex™-FE-S Filters PTFE Membrane Memtrex-FE-S validatable sterilizing grade filter cartridges are designed for sterile venting and final filtration of pharmaceutical fluids.
