2020/2/17 · 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.

2005/5/6 · An aliquot of the preparation was filtered through a 0.45-μm-PTFE membrane filtration cartridge (Gelman Sciences, Dreieich, Germany) directly into a vial and transferred into the HPLC autosampler. Powdered samples of the phytopharmaceutical dosage form (Sogoon tablets, Steiner and Co., Berlin, Germany), equivalent to about 215 mg of the extract, were treated in the same way.

2006/1/1 · Solvents for preparing the mobile phase were filtered through Phenomenex nylon membrane filters with 0.45-μm pore size and the sample extracts were also filtered using polytetrafluoroethylene (PTFE) membrane filters, (13 mm, 0.5-μm pore size; MFS, Dublin

PTFE is an inherently hydrophobic membrane excellent for filtration of organic-based, highly acidic or basic samples and solvents. Widely used in chromatography, it is especially well suited for the clarification of non-aqueous samples. Although this membrane is hydrophobic, it can be made hydrophilic by wetting the membrane with alcohol and then flushing with deionized water.

Regenerated cellulose in HPLC filters. High-performance liquid chromatography (HPLC) is a versatile technique for chemical analysis that employs a range of different solvents depending on the application. HPLC benefits from filtration during sample preparation to remove particulates.

—HPLC grade. Preparation of solutions and standards.— Curcumin stock solution, 1000 μg/mL (CUR-1000) .—Weigh an amount of curcumin primary standard equivalent to 10.0 mg after correction for purity and place in a 10 mL volumetric flask.

HPLC-certified non-sterile syringe filters are available with nylon, regenerated cellulose or polytetrafluorethylene (PTFE) membranes in polypropylene housing for extra chemical resistance. Sterile tissue culture-tested syringe filters are available in PES, regenerated cellulose, or surfactant-free cellulose acetate membranes in either polypropylene or acrylic copolymer housings.

2018/1/17 · The supernatant layer was syringe filtered using a 0.2-μm PTFE membrane before performing the experiments. Triplicate sample preparations were done on each sample, and two separate HPLC injections were carried out for each replicate preparation.

2009/2/15 · The resulting solution was filtered through a 0.2 μm PTFE membrane (Acrodisc ® CR 25 mm Syringe Filter, PALL Life Sciences) into autosampler vials. HPLC analysis was performed using an Aijiren Series system, equipped with pump, degasser, autosampler, spectrofluorimetric detector and system controller with a PC control program.
