Polycarbonate Membrane Filters
Chemical compatibility information
Introduction:
The question of chemical compatibility of the polycarbonate track etch membrane filters
often times arises, since one often times has the need to filter a liquid other than water.
We find the two brands offered by SPI Supplies, both our own SPI-Pore™ as well as the Nuclepore®
brands are quite similar, if indeed one can measure any difference in their chemical compatibilities.
We offer the following information:
Not recommended
Acetone
Ammonia, 6N
Carbon tetrachloride
Chloroform
Dioxane
DMSO
Nitric acid 6N
Nitrobenzene
Pyridine
Sodium hydroxide 6N
Sulfuric acid, concentrated
Trichloroethane
Resistant to following solvents:
Aceitic acid 5%
Amyl acetate
Boric acid
Butyl alcohol
Cyclohexane
Ethanol
Ethers
Ethylene glycol
Formaldehyde
Freon® TF
Precision Cleaning Agent®
Hydrochloric acid, concentrated
Hexane
Isobutyl alcohol
Methanol
Nitric acid, concentrated
Pentane
The above information should be used only as a guide to your selection of membrane and solvents.
For filtration of a liquid for which polycarbonate track etch membrane filters are not the right
choice, consider the SPI-Pore™ Silver Membranes
or the Anodisc® aluminum oxide membrane filters.
