Feb 17, 2020 · A PTFE syringe filter is an ideal choice for filtering and de-gassing chromatography solvents. With proper pre-wetting (commonly used alcohol), aqueous samples are also compatible. When using air-vents, these syringe filters are capable of stopping moisture from passing through. Workable pH range: 1-14.
Laboratory Filtration Products. High quality RephiQuik Nylon, PTFE, PES, PVDF and MCE syringe filters for sample preparation are manufacutured at ISO certified plant. RephiQuik filters ensure the lowest UV-visible absorption of extracts by HPLC detection at 210 nm and 254 nm, with water, methanol and acetonitrile as extractants.

Six types of popular syringe filters were tested, including nylon, glass fiber prefilter/nylon (GF/Nylon), RC, PES, PTFE, and GF/PTFE filters. Based on the sample medium of each drug, four different kinds of filters were evaluated for each drug.
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.
The ability of Millex® HPF filters with hydrophilic PTFE membrane to process various sample types (20% orange juice in water, v/v; protein shake 2 mg/mL, and Benadryl® antihistamine syrup) was tested by measuring the volume filtered before the filter clogged.
