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.

Ultrafiltration rate (water), clearance (aqueous solutions) at 37°C
Measured good:
Dialyzers with Low Flux and High Flux Membranes
2 – Measuring stand: Hydraulic permeability (fiber)
Application: Quality assurance in the production and development of fibers for dialysis
Measurement parameters:
hydraulic permeability (water) at 37°C (analogous to UFR for modules)
