time of equipment are costly. A simple upfront and easy solution is the incorporation of Thomson Filter Vials. The Thomson SINGLE StEP Filter Vials 35540-200 (200 per pack) or 35540-500 (500 per case) (patent pending) are comprised of three parts: Pre-slit cap, plunger filter with 0.45µM Teflon membrane and the outside shell vial that holds 450uL.
10118-322 10118-326. Thomson SINGLE StEP Standard Filter Vials, Restek. Filters Syringeless Filters. Recommended for samples containing less than 10% solid particulates, these standard filter vials are constructed using PTFE or PES for long-lasting durability. Minimize sample loss by eliminating multiple transfers.
Thomson SINGLE StEP® Filter Vials • Easy-to-use vials offer fast sample filtration and require only a squeeze of your fingers. • Color-coded caps allow easy identification of 0.2 μm or 0.45 μm membranes in PVDF, PTFE, PES, or nylon. • Pre-slit PTFE/silicone caps help eliminate broken autosampler needles and cored septa.
Thomson Filter Vials No multiple step transfers needed. Pre-slit caps for all filter vials, with the exception of the low evaporation caps, ensure a no-hassle, clean aliquot withdrawal. No more breakage of expensive needles or coring problems on the HPLC or Mass Spectrometer. Thomson Filter Vials are compatible with most standard autosamplers.
Dilute ampicillin sodium salt to 100 mg/mL in sterile water to make stock solution. After dissolving, sterile-filter through a 0.22 μm PES filter, aliquot and store at −20°C for up to 1 year. Use at a working concentration of 100 μg/mL.
Chrom Tech Filtration. Laboratory f iltration supplies are vital for laboratory equipment to operate effectively long term. Filtration is a simple method for trapping particles before the sample is analyzed.
Filter Vial Completed with Filtrate Removed from Sample Fast and Easy to Use Fast Sample Filtration in One Easy Step Simply transfer your sample into the vial, press down on the plunger filterand your sample is ready for use in an autosampler. • An all-in-one replacement for the syringe, syringe filter, vial, cap and septum • Easy to press down
top of each column. For the Captiva Premium PES syringe 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

Feb 17, 2020 · With PES syringe filter membrane mechanically strong character, it can handle high-temperature liquids, with great flow rate (better than PTFE), and low protein binding. With these features, PES syringe filters offer superior performance for use with biological samples and media culture. Workable pH range ~3-14.
Syringeless Filters. Available in a variety of filter media, syringeless filters allow you to process sample loads in a fraction of the time, providing a quick, economical, and environmentally conservative way to filter samples prior to HPLC analysis. These are preassembled filtration devices specially used in HPLC for the purification and

The Thomson PTFE Filter Vials for HPLC can do this easily by mixing the acetonitrile and aqueous solution in the bottom chamber, and then allowing the filter to push down trapping the protein and letting the clean sample come through for analysis. Filter, vial, and cap—all in one design. Simple to use and easy to press down—No tools required!
Color-coded caps allow easy identification of 0.2 μm or 0.45 μm membranes in PVDF, PTFE, PES, or Nylon. Fit most standard 12 x 32 mm autosamplers. Standard|Filter Vials are designed to speed up sample prep and minimize transfer steps. Available in a variety of membranes and pore sizes.
Whatman filters are world-renowned as a standard for laboratory filtration and are associated with quality, reliability, and reproducibility.
