Hahnemühle Life Science Lab Filtration Membrane filters Cellulose Nitrate

Cellulose Nitrate Membranes

Recommended for clarification and sterilisation of aqueous solutions, microbiological analysis and particle

counts.

Made of cellulose nitrate, hydrophilic.
Very high flow rate
High non-specific adsorption.
Qualified for aqueous solutions (pH 4-8), hydrocarbons and some dilute solvents.
Very uniform pore structure which ensures homogeneous distribution of the particles retained on the filter surface.
Maximum temperature 130ºC
Available in white or black, gridded (3.1 x 3.1 mm) or plain, sterile or non-sterile.
Pore size from 0.2 μm to 8 μm with a sharp size distribution
Filter diameters from 25 mm to 50 mm
