Laboratory Filters | Filtration Products | Waters
Filters are packaged into separate tubes to protect them from external sources of extractables. While one tube is in use, the others are kept sealed. Excellent chemical resistance. Use this universal filter for all your LC-MS samples. The WWPTFE (water wettable polytetrafluoroethylene) membrane can be used with both organic and aqueous solvents.
Choice™ PTFE (Hydrophobic) Syringe Filters
Use Thermo Scientific Choice PTFE Hydrophobic Syringe Filters for filtration of aggressive organic, highly basic or hot solutions and as transducer protectors. They can filter aqueous solutions after pre-wetting with an alcohol. These syringe filters provide cleaner sample extracts by removing inter

Syringe Filters for HPLC and sample preparation | analytics
The filter size depends highly on the filtration volume. For small volumes (< 1 ml), syringe filters with a diameter of 3 mm are usually for medium volumes (1-10 ml), 15 mm and for large volumes (> 10 ml) 25 mm. Common pore sizes for UHPLC and HPLC columns with small particle sizes (< 3 µm) are 0.2 and for columns with larger particle sizes (> 3.5 µm) 0.45 µm, respectively.

Whatman 9911-2502 Uniflo, 25 mm, 0.22 PTFE, (Pack of 500
Jun 15, 2019 · The most common application is HPLC sample filtration. PTFE membrane filters are hydrophobic and will not allow water to pass without high pressures. Aqueous solutions may be filtered if the membrane is initially wetted with alcohol or another appropriate solvent. PTFE membranes will stop aqueous aerosols in gas streams.
AQ™ Syringe Filters - Microsolv Technology Corporation
25mm Filters - Standard size for Chromatography labs and our most popular size. 4mm Filters - Used when sample size is under 1ml and residual volume must be minimized. Cellulose Filters - Use with Aqueous solvents and when biological activity should be maintained.
