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. Use Table 1 to match your applications with a recommended membrane and pore size. Table 1. Selecting
The PSF syringe filter has larger effective filtration area compared with the older traditional model, 3.9 cm 2 compared to 2.8 cm 2. This gives the PSF syringe filter a much improved throughput and flow rate. PTFE PSF syringe filters are available with a multi-layered glass fiber prefilter (GxF) above the PTFE membrane.
Foxx Life Sciences. EZFlow 25mm, 47mm, and 90mm membrane disc filters are used to retain particles or microorganisms by surface capture. The membrane disc filters are available in 0.22µm or 0.45µm pore sizes. The Hydrophobic PTFE membrane is bonded to a polypropylene support and due to its extreme chemical.
standard grade 0.2 um PTFE filter for solvent prefiltration Merck PTFE membrane filter 0.2 um for solvent prefiltration 网页2021/10/29 · Aervent-50 0.2 µm hydrophobic filters contain a 50 mm Aervent PTFE membrane in a bi-directionally supported polypropylene casing.
The hydrophobic PTFE membrane filters are made of polytetra-fluorethylene (PTFE) only and are therefore permanently hydrophobic. Unlike hydrophilic filter types, they are not wetted by air humidity. Item no.: 11807--47------N. Price (USD): $493.00.
Product Support Whatman PTFE membrane filters from Cytiva's business are chemically stable and inert, making them suitable for use with aggressive organic solvents, strong acids, and alkalis. The TE range features polypropylene support material for improved strength and handling Temperature resistant up to 120°C
Aug 7, 2018 · Regenerated Cellulose (RC) Membrane. A versatile cellulose-based hydrophilic membrane that is resistant to a very large range of solvents, including aqueous solutions and organic solvents. Recommended for use in HPLC and protein recovery applications. DO USE: with most common solvents, including those used in HPLC.
Nylon filter membrane, 47 mm diameter, 0.20 µm pore size, 100/pk 5191-4341 Description Part Number PTFE filter membrane, 47 mm diameter, 0.45 µm pore size, 100/pk 5191-4336 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
A pore size of 0.2 µm is small enough to remove microbes from solutions; a 0.45 µm ore size can remove larger particulates. Color and Grids White membrane filters may be plain or marked with square grids (outlined in black) that can help with enumerating particles.
The 0.5 μm pore size is normally used. Air and gas sterilization make use of the hydrophobic characteristics of PTFE membranes and their ability to stop aqueous aerosols. Usual pore sizes are 0.2 μm and 0.5 μm. Sterile venting of vacuum manifolds, fermentation vessels, and sterile filtrate tanks and containers utilize PTFE 0.2 μm membranes.
