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
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. If the membrane dissolved, or otherwise lost its strength, or changed significantly in appearance, it was rated
With high concentration salts use titanium filters –P/N: 700005378 (SOLVENT FILTERS, Ti, 7pk) When contamination is suspected, can be washed –Backflush with 70% organic solvent (IPA, EtOH or MeOH) in water –10 ml at minimum, with a syringe (luer-lock) Regular (SS) solvent filters –P/N 700003615 (Filter, Solvent Bottle, SS, PKG 1)

Syringe Filter Housings Syringe filter housings are manufactured from solvent-resistant, low-extractable polypropylene resins specifically selected for wide compatibility with common HPLC sample matrices. Solutions at temperatures up to 100°C can be filtered using syringe filters. Syringe filters can be sterilized by autoclave at
Water and acetonitrile were passed through polypropylene or PTFE syringe filters (as indicated in legend), then used 1:1 (v/v) to prepare the mobile phase for UHPLC. The system was run at 0.25 mL/min for 600 min with backpressure recorded every 50 min. DP represents total change in backpressure after 600 min.
Apr 25, 2012 · We first filter through a coffee filter to remove the gross material and then through a Whatman #1 lab filter, using a vacuum assist, to save time. Micro filtration: Once it has been rough filtered, we then follow up by polishing it at 0.2 microns, using a 0.2 micron syringe filter.
