GE Whatman® Membranes feature very narrow distribution of pore sizes for superior batch-to-batch consistency. They are manufactured from cellulose nitrate and are highly flexible with very low levels of extractables that can interfere with tissue culture and trace analysis applications.
Membranes can be autoclaved at 121ºC without loss of integrity and with minimal shrinkage. Circular membranes are 47 mm in diameter with a 0.45 µm pore size.
Extremely strong and flexible – less likely to be damaged during loading
Very low extractable levels
Suitable for pharmaceutical, immunological, tissue culture, and trace analysis applications
