Additionally, the batch-to-batch variation is minimized providing more consistent laboratory results. Porosity. Low extractable levels the level of extractables in membrane filters has become more important with advances in filtration or adsorption techniques. Thickness 105 to 140µm. Applications sample preparation. Whatman cellulose nitrate membrane filters have a noticeably improved flexibility and are made to tolerate abuse during handling, loading and autoclaving without sacrificing integrity. Whatman cellulose nitrate membrane filters have a low level of extractables, generally below that of other membranes of a similar type. Filtration of aqueous solutions. Microbiological studies. Cellulose nitrate membranes are supplied as circles, sheets or reels. It may also cause a reduction in flow rate and total throughput. Whatman membranes exhibit a low shrinkage during autoclaving.
