2014/1/1 · The pigment extract was then filtered onto a 0.2-μm PTFE syringe filter with a very low dead volume of <10 μl (ReZist series ∅ 13 mm, Whatman Inc., Florham Park, NJ, USA) and analyzed using the HPLC analytical protocol described above for periphytic
Syringe-deposited calibration compounds form patches of material when the solvent evaporates, whereas collected aerosol particles stay as separate particles on the filter. The atomized particles have much higher surface-to-volume ratio compared to the syringe-deposited patches and so a similar total amount of deposit will evaporate more quickly from the filter.
2013/6/21 · Polymer samples were prepared for films as follows: 5 wt% solutions of polymer/DMSO were prepared by heating, stirring and filtration through a 0.45 μm PTFE syringe filter. Polymer films were drop cast on stainless steel shims, and were left on the bench overnight to allow a bit of solvent to evaporate off, leaving a “tacky” film.
2008/9/2 · Saturated solutions were prepared by filtration of a drug suspension, stirred overnight, through a 0.45 μm nylon 47 mm membrane filter (Millipore Corporation, Bedford, MA, USA). For griseofulvin, a saturated solution of the drug containing 5 mg/ml TPGS was used, since severe agglomeration occurred upon dilution in a saturated solution without TPGS.
pp pleated filter cartridge deliver high effciency and consistent filtration of fluids in the food and beverage industry. They are constructed of pleated membrane filter media that provides removal of partical from 0.1 to 60 micron, the pore size is not affected by the vibration of feeding pressure, due to its uique low differential pressure, high flow volume, excellent filtration microns.

Thursday, September 16, 2010. One of the important characteristics in membrane selection is whether you want a membrane that is Hydrophobic or Hydrophilic. Here we'll define these terms, as well as provide some examples of membrane materials and applications for both types. Hydrophilic literally means “water loving.”.
2020/3/15 · At the predetermined time point, reaction samples were collected with syringes and immediately filtered through 0.45 μm PTFE syringe filter discs. Meanwhile, reactive radicals were quenched by excessive EtOH in case of further degradation of CBZ in the solution.
