Membranes


Membranes enable a very convenient, fast and economical separation.
Often they are also used as a neutral sample support for further analysis.

Overview of available membrane filters

Material Properties and pore sizes Type
Cellulose mixed esters

– suitable for aqueous solutions
– also available sterile and/or
with grid
– recommended for gravimetric
analysis
– autoclaving possible at 121 °C
– economical
– pore sizes 0.2 – 0.45 µm

PORAFIL® CM

Cellulose mixed esters,
fabric-reinforced
– suitable for aqueous solutions
– higher mechanical stability than
PORAFIL® CM
– pore sizes 0.2 – 0.45 – 0.8
PORAFIL® MV
Cellulose nitrate – thermally stable up to 125 °C
