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.
Syringe Filter Housings. 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.
Target2 PTFE Syringe Filters are used for general biological filtration. They are especially well-suited for applications where high protein recovery is desired. Target Polypropylene Syringe Filter Housings Meet The Requirements of 21 CFR 177.1520. Target 2 PTFE (Hydrophobic) Syringe Filter 0.2 µm, 17 mm, 100 Pk.
Polymer-filled PTFE high wear resistance, low wear to shaft/bore. FDA compatible. SP 83 . Polymer-reinforced PTFE. Excellent compatibility with most fluids and gases. Limited compatibility with acids at high temperatures. T 6
There are so many solvents and syringe filter/membrane materials that it can be tough to remember which combinations are safe and which are corrosive. These tables show the compatibilities between 5 materials (CA, nylon, PES, PTFE, and PVDF) and 75 common solvents (including acids, alcohols, and nitrogen solvents).
compatibility with the liquid you want to filter by performing a trial filtration run before you start your actual filtration. Legend Compatible ++ Limited compatibility + Not compatible - not analyized n.a. 1) gamma irradiation feasible for Minisart ® Air Chemical Compatibility Chart For Minisart® Syringe Filters
biological fluids. Refer to Table 3 for more chemical compatibility information. Polypropylene (PP) is used in the Spin-X® centrifuge filters and some of the syringe and disc filter housings. This plastic polymer has very good resistance to many solvents, refer to Table 3 for more chemical compatibility information.
We carry PTFE syringe filters for making liquid culture lids in both 13mm and 25mm diameters. We also offer the largest selection of synthetic filter discs online. Our synthetic filter discs provide for contaminant-free gas exchange on spawn jar lids. All of our synthetic filter discs have a pore size of 0.3 microns.
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
Filter Media Selection Guide. 1. Determine whether your application requires prefiltration. 2. Choose the suitable membrane filtration media. 3. Choose the suitable diameter. 4. Choose the suitable pore size.
Millex ® hydrophilic PTFE syringe filters boast low analyte retention, with ≥90% recovery of small molecules – matching or exceeding the performance of other equivalent filters. Figure 2. Comparison of small molecule retention of 0.45 μm hydrophilic PTFE syringe filters from different vendors. Figure 3.
