Filter Membrane Cut Discs
0.45 micron CN (cellulose nitrate) membranes are certified for water quality work.
Precut filter membrane discs are convenient to use and have low levels of extractables.
Nalgene* Filter Membranes
Thermo Scientific* Nalgene Filter Membranes are ideal for use in particulate and microbial analysis.
Nalgene* Glass Prefilters
Thermo Scientific* Nalgene glass fiber prefilter discs increase filtration speed and throughput of highly viscous or heavily particulated solutions when used in conjunction with any Nalgene MF75 filter units or bottle top filters.
