Mar 01, 2019 · Afterwards, the sample was filtered through a 0.22 um polytetrafluoroethylene (PTFE) filter into a high-performance liquid chromatography (HPLC) vial for subsequent BPA concentration measurement. For the construction of [email protected] membrane reactor, a 5 mL suspension containing well-dispersed [email protected] catalyst (0.5 mg) was
The Thomson PTFE Filter Vials 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.
Whatman ® Spartan ® syringe filters provide reproducible filtration of organic and aqueous solutions for high performance and ultra-high performance liquid chromatography (HCLP and UHPLC) sample preparation. For batch-to-batch consistency, these filters are tested and certified for the absence of UV-absorbing substances at wavelengths of 210
Briefly, the blend was dissolved in water, filtered through PTFE (0.22 µm) membranes and separations performed using an Aijiren series instrument (Aijiren Technologies, Santa Clara, CA) with a Kinetex F5 pentafluorophenyl HPLC column (2.6 µm, 100 × 4.6 mm) and SecurityGuard® cartridge (PFP, 4.0 × 2.0 mm) (Phenomenex, Torrance, CA). ..

Nest syringe filters have pore size either 0.22µm or 0.45µm, and diameter 13mm or 25mm, with membrane materials either with PES or PVDF membranes. For sample volumes of 2mL to 100mL. Retention volume <115µL. Maximum operating temperature: 100°C autoclave at 125°C for 15 min. Maximum operating pressure approximately 100 ps.
Millipore® membranes have supported laboratory filtration in academic, pharmaceutical, and industrial sectors since the 1950s. We provide a range of membrane chemistries including MF-Millipore® mixed cellulose esters, Durapore® PVDF, Millipore Express® PLUS polyethersulfone, as well as hydrophilic and hydrophobic PTFE.
Millex-GV Filter, 0.22 µm A 25 mm diameter sterile syringe filter with a 0.22 µm pore size hydrophilic PVDF membrane. Comes in a pack of 50. - Find MSDS or SDS, a COA, data sheets and more information.
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

biological fluids and gases is usually done with 0.2 or 0.22 µm pore filter membranes. Clarification and prefiltration of solutions and solvents is best accomplished with 0.45 µm or larger filter membranes. Prefiltration to improve filter performance can also be accomplished by the use of glass fiber prefilters that can be purchased separately.
