GVWP04700. Trade Name. Durapore ®. Description. Durapore® Membrane Filter, 0.22 µm. Background Information. Durapore® membranes provide high flow rates and throughput, low extractables and broad chemical compatibility. Hydrophlic Durapore® membrane binds far less protein than nylon, nitrocellulose, or PTFE membranes.

Fraction 3 underwent 5 filtration cycles through a 13 mm PTFE 200 nm syringe filter device (Fisher Scientific Ltd., Hampton, NH, USA) with polypropylene housing. Fraction 4 was frozen in liquid nitrogen, thawed in a water bath at 60 °C and vortexed for 3 s. The samples undergo 4 of these freeze-thaw-vortex (FTV) cycles.

Useful for alcohols, cryoprotectants such as DMSO and with aqueous/biological and weak solvents. Polypropylene housings with pink color rings. PTFE. Naturally hydrophobic. Excellent for HPLC/GC solvent filtration. Ideal for sterile venting of air or other gases during filtration. Polypropylene housings with white color rings.

Feb 09, 2016 · Polypropylene glycol or polypropylene oxide is the polymer of propylene glycol (CH 3 –CHOH–CH 2 OH). Chemically it is a polyether with the chemical formula H-[O-CH(CH 3 )-CH 2 ] n -OH.

Innapropriate filter size will can cause a filter to plug prematurely. Filter pore size is chosen based on the application. If the application requires a sterile fluid, than a 0.22 micron membrane would be used for standard solutions that have bacterial bioburden. A 0.1 micron filter would be used for applications where mycoplasma is a concern.
