Using the principle of bubble pressure method (also known as capillary flow method and gas-liquid discharge method), the bubble point pressure, maximum pore size, average pore size, maximum pore size and gas permeability of various microfiltration membrane materials can be accurately tested, and the pore size distribution of the material can be intuitively displayed in the form of a chart, which can detect the defects of the sample and estimate the filtration accuracy.
Dimensions: 420(L)×480(W)×230(H) mm
Working medium: compressed air, cylinder gas
Pore size test range: 0.08~500μm
Pressure range: 0~600kPa
Test objects: flat membrane, tubular membrane, hollow fiber membrane
Instrument function:
1. Bubble point pressure test
2. Gas flux test, gas permeability test
