sterile 0.22 um ptfe filter Acrodisc-Voa Vial Supplier 8/1/2017 · PTFE membranes are chemically resistant to nearly all solvents, acids and bases. The membrane has low extractable and good thermal stability. PTFE is hydrophobic and requires pre-wetting prior to use with aqueous solvents.
1) Syringe filter housings are manufactured from solvent-resistant, low-extractable polypropylene resins specifically selected for wide compatibility with common HPLC sample matrices. 2) Solutions at temperatures up to 100°C can be filtered using syringe filters. 3) Syringe filters can be sterilized by autoclave at 125°C for 15 minutes.
Supplier: Pall Laboratory Next generation of universal hydrophilic PTFE membrane with maximum chemical compatibility when filtering both aqueous solutions and aggressive solvents. Hydrophilic Low protein binding HPLC certified for low extractables assuring that the filter will not add artifacts or contamination to your analysis.
Clear PTFE (Hydrophobic) Syringe Filters, 0.45 µm, 4 mm (200/Pack) have broad chemical compatibility and high pH resistance.
