GE Healthcare's Whatman Regenerated Cellulose (RC) Membrane Flexibility is one of the key criteria requested in filter media used for chromatography sample preparation and solvent preparation. Users expect solvent compatibility, robustness, low protein binding, filtration efficiency, purity, and a
1/12/2020 · Liang et al. reported a stretchable TENG based on polytetrafluoroethylene (PTFE)-PU bilayer membrane and PU-Ag nanowire electrode. However, VHB tapes and a hot-press process are needed for device assembly and the stretchability of the device relies on PU [ 43 ].
PTFE membrane was observed by an FE-SEM (Aijiren 8500). 2.4 Activity assay of immobilized lipase P-Nitrophenyl acetate (p-NPA), was used as substrate to test the hydrolysis activity of the lipase and the assay was carried out at room temperature (25 C
For use with Aijiren , , , and autosamplers.In liquid chromatography, the syringe functions primarily as a pipette or liquid-transfer device that loads a sample loop. The same largely holds true for gas chromatography. The syringe generally does not take an active role in injection, which occurs only after the sample has been displaced from the syringe. These syringes are
