Measuring instruments for hollow fiber membranes

Measuring instruments for hollow fiber membranes

Alpha Plan is a manufacturer of various measuring stands for performance measurement of membrane filters. They support the development of membrane fibers or their end products (e.g. dialyzers) and are a perfect addition for quality assurance for a membrane filter production. The benchtop units are compact and flexible to use.
