solvent compatibility ptfe membrane filter 0.22 um for minerals

Chemical Compatibility. PES membranes were exposed to the following chemicals for 48 hours. If there was no significant change in the bubble point, strength or appearance of the membrane, it was judged compatible with the chemical.

depends on the sample medium and the filter membrane’s chemical compatibility. • For aqueous samples, hydrophilic-type membranes are preferred, such as cellulose acetate (CA) or polyethersulfone (PES). • For organic samples, especially with aggressive solvents, polypropylene (PP) or polytetrafluoroethylene (PTFE) filters should be used.

The Aervent membrane contributes to lean processes due to its non-fiber releasing properties. Aerex® - 0.2 um hydrophobic polytetrafluoroethylene (PTFE) membrane features broad chemical compatibility and low gravimetric extractables. Durapore® - 0.22 um hydrophobic membrane is manufactured to maximize retention and strength. Durapore

This is difficult to relate to a membrane that may respond almost immediately to immersion in solvent. In addition, solvent-membrane compatibility requires additional consideration of filtration-specific factors. None of these published compatibility guides, for example, monitors the solvent’s ability to wet a membrane or increase extractables.

Aug 07, 2018 · 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.

PTFE Chemical Compatibility Chart: Polytetrafluoroethylene is very non-reactive and ideal for use with most chemicals.. Review the chemical compatibility of Teflon® and PTFE with various chemicals, solvents, alcohols and other products in the cart below.

0.20-0.22: Membrane Thickness: 100-140µm: pH Range: 3-12: PTFE - Strong Chemical Compatibility - HPLC Certified - Hydrophobic. Advanced Quality PTFE Syringe Filters,

Durapore™ PVDF Membranes: 0.22μ Pore Size provide high flow rates and throughput, low extractables, broad chemical compatibility and low protein binding. Available in diameters ranging from 13mm to 142mm. Composed of polyvinylidene fluoride (PVDF) that binds far less protein than than nylon, nitrocellulose or PTFE membranes

Polyethersulfone membrane (PES) low protein adsorption, high flow rates, a wide range of PH value, chemical compatibility, applicable to the preparation of the samples, aqueous solvent filtration, microbial research, environmental analysis, biological analysis, HPLC mobile phase filtration; Polytetrafluoroethylene (PTFE) and inert chemical

Membrane Filter Chemical Compatibility Chart Use the information in this table to determine the ability of a specific membrane filter to withstand exposure to a solvent. All concentrations are 100% unless noted.

PTFE membrane filter is made of polytetrafluoroethylene ultrafine fibers by hot-melt bonding together. Difference from glass fiber membrane, PTFE filter is a kind of membrane material for deep filtration. Membrane filter disc has the following characteristics: membrane filter 0.22 μm is produced from food-grade isotactic polypropylene. See full list on hawachmembrane.com
