Merck 0.2 um ptfe filter for hplc

Pore Size (0.2 and 0.45 µm) — The filter pore size is usually a personal preference of the chromatographer but relates to the column packing material. Since there are many different packing materials, a general guideline is that most customers find that the 0.45 µm filter meets their requirements, although chromatographers are increasingly

Color-coded caps allow easy identification of 0.2 μm or 0.45 μm membranes in PVDF, PTFE, PES, or nylon. Preslit PTFE/silicone caps help eliminate broken autosampler needles and cored septa. Rugged polypropylene vial houses insert with 450 μL loading capacity and low dead volume (120 μL).

Jan 08, 2017 · Polytetrafluoroethylene (PTFE) 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. Membrane: HPLC certified PTFE, with polypropylene support

View PTFE Syringe Filters View Hydrophilic PTFE Syringe Filters. Regenerated Cellulose (RC) Regenerated Cellulose is a hydrophilic, solvent resistant, low protein binding membrane. R C membrane is ideal for removing particulates from HPLC samples, prior to injection. This membrane is compatible with all HPLC solvents, and can be utilized for

Filtration products by Merck. At Analytics-Shop you find a large selection of membrane filters and syringe filters by Merck Millipore. We offer a broad variety of different filter membranes of high quality, e.g. Merck Millipore millex syringe filters and ominpore or isopore membrane filters by Merck Millipore.

What membrane filter pore size should I use for sterilization? Regardless of the membrane filter material, always use a 0.2 µm pore size membrane filter as the final filter for any sterilizing filtration. The 0.2 µm membranes used in Thermo Scientific™ Nalgene™ filters have been tested and shown to retain 100% of a challenge of 1 X 107

Syringe Filters Solvent Compatibility Chart 1 Protect any analytical system. 2 Extend LC column lifetime. 3 Achieve more reproducible analyses. 4 Variety of membranes, porosities, and diameters available. 5 Luer lock inlet provides strong, leak-tight syringe connection to withstand filtration pressure.

filter, excellent and consistent recoveries were obtained through low to high levels for dimer and monomer. All of the other PVDF syringe filters gave very poor recoveries at low levels (0.1 and 0.2 mg/mL), especially for dimer. The results demonstrate that Captiva Premium PES filters can firmly support the analysis of low level protein samples
