Overview
The integrity bubble point pore size tester is a dual function pore size analyzer, which has both gas-liquid and liquid-liquid testing methods. It is used to detect and analyze the pore structure of porous materials such as microfiltration, ultrafiltration, nanofiltration flat membranes, tubular membranes, and hollow fiber membranes (which can be used by internal pressure and external pressure methods), hemodialysis membranes, lithium battery separators, ceramic tubes, rock cores, electrospinning, non-woven fabrics, etc. The microporous characteristics of various materials, such as narrow pore size (including large pore size, bubble point, pore size distribution), liquid permeability, gas permeability, etc. in through-hole channels ... wait.
Product Details
Characteristics
- The gas-liquid and liquid-liquid dual testing method pore size analyzer is a through-hole pore size analysis device that combines gas-liquid and liquid-liquid methods. It has the ability to measure the pore size of large pores from 500 microns to tens of nanometers using gas-liquid method, as well as the function of dual liquid method, accurately measuring pore sizes from less than 30 nanometers to several nanometers.
- Full aperture range measurement: from 0.005 microns to 500 microns (pressure requirement is 0-200psi)
- Simultaneous detection and analysis performance for both gas and liquid flow and high flow areas (0.0001cc/min~200L/min)
- Advantages: It can work under room temperature and low pressure conditions, has a very short testing time, requires very few operators, and is harmless to the environment.?
