Aug 07, 2018 · Charting compatibility. Hopefully, this quick overview helps you identify the most appropriate membrane-solvent combination for your application. To compare between all the common membranes and solvents, review the chemical compatibility chart in our guide to laboratory membrane filtration principles and chemical compatibility.
Nylon and PTFE (Teflon) membranes have broad chemical compatibility and can be used to filter most HPLC and GC fluids/solvents. PTFE can also be used to filter air or gases. Nylon is good for DMSO. PES and CA/SFCA membranes are compatible with non-alcoholic aqueous solutions and
PTFE membrane hydrophilic can also be used with compatible non-aqueous fluids. Vacuum membrane filter 0.45 μm is usually not used for air, gas, or exhaust filtration because if they get wet accidentally, for example through condensation, the filter will block the flow. The hydrophobic PTFE membrane filter disc is modified to obtain a
MEMBRANE FILTER CHEMICAL COMPATIBILITY CHART. Chart below shows the Chemical Compatibility of various types of membrane filters with some commonly used 0 chemicals. All types of membrane filter products were exposed to specified chemicals/reagents for 3 days at 25 C. Upshot: All products retain its Integrity after Chemical compatibility Test.
Ec21 ptfe 0.22 micron filter for solvent prefiltration-Voa Laboratory filter membranes, also known as cut disc membranes, are used in conjunction with filter holders and other har +8618057059123 Email: market@aijirenvial.com
PTFE is the most versatile plastic in terms of chemical compatibility. Low temperature: maintains high strength, toughness and self-lubrication as low as 5°K (-268°C /-450°F) and good flexibility at 194°K (-79°C / -110°F) NOT compatible with certain alkali metals and fluorinating agents such as xenon difluoride and cobalt (III) fluoride
Aug 07, 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.
Chemical Compatibility Reference Chart Teflon® PTFE Teflon®* PTFE Chemical Compatibility Chart: Check the chemical compatibility of Teflon® and PTFE with various chemicals, solvents, alcohols and other products. Polytetrafluoroethylene (PTFE) is very non-reactive and is often used in containers holding reactive and corrosive chemicals.
Minisart® SRP15 Syringe Filter 17573----------K, 0.2 µm. The low-binding PTFE membrane is the best option for leachable free filtration whenever highest chemical compatibility and pH values of 1 - 14 are needed. For hydrophilic solutions pre-rinsing with a solvent is necessary to make the hydrophobic membrane permeable for aqueous liquids.
Choose From a Variety of Membranes. • Millex-LCR filter contains a Millipore-exclusive hydrophilic PTFE membrane and are HPLC-certified for low levels of UV-absorbing extractables. They provide the cleanest sample for HPLC analysis. • Durapore®(PVDF) filters combine fast flow with low protein binding.

Due to its strength and broad chemical compatibility, PTFE is commonly used in membrane filters. While PTFE is known for its high strength, the addition of a high-density polyethylene (HDPE) backing offers improved filter handling characteristics. Hydrophilic LCR and Omnipore™ PTFE membranes are typically used for filtering aqueous solutions.
These tables show five common syringe filter materials -- Cellulose Acetate (CA), Nylon, PES, PTFE, and PVDF -- and their compatibilities with 75 common solvents. Compatibility Tables Compatibility Grades. The tables below indicate a compatibility grade for each material/solvent combination. Safe means that the combination is confirmed compatible.
