Polypropylene (PP)
Multi-range pH testing
Indicator strips for fast pH measurement across multiple ranges, including universal and comparator papers
Polypropylene membrane filters are best suited for the filtration of organic solvents due to their natural hydrophobicity. However, polypropylene membranes can filter aqueous solutions once wetted with alcohol.
