Based on bubble-point (capillary-flow) theory, the porometers automatically analyze the pore-size distribution of various micro-filtration materials (filter paper, carbon paper, porous ceramics, sinter metals, polymer membranes, woven & non-woven textiles, and glass filters).
Based on liquid-liquid displacement theory, the PSMA porometers measures pore size of 2 - 500 nm. Apart from ultra-filtration membranes, the pinhole defects in nano-filtration, reverse osmosis and the molecular-sieve membranes can be also analyzed.
Integrity testing is critical for evaluation on filter defects and damages. Our testers offer multi-functions.
Configure a constant temperature and water purification system, using multiple sensors to accurately measure water flow rate over a wide range. It can perform both positive pressure (0－1 MPa) and negative pressure (-50 kPa－0) suction tests (especially important for hollow plate membranes).
Molecular weight cut-off (MWCO): The molecular weight of the solute when the membrane retention rate is 90%.
Liquid flux, retention rate, molecular weight cut-off, filter regeneration and stability, separation factor, etc.
The GaoQ small animal blood collection instrument is based on five precise peristaltic pumps, which efficiently control fluid delivery. Coupled with a coaxial sensor, it ensures the collection of pure blood samples. The integrated low-temperature stepwise collector design further enhances sample preservation stability.
Against drawbacks of the sessile drop method, our patented testers measure the contact angle and interface tension inside of the filter pores.
Many industrial and domestic fields require gas dedusting, the methods mainly include filtration, electrostatic precipitation, cyclone separation, inertia, and wet methods (such as spraying, venturi, and foam). Filtration methods have higher dedusting precision, and various permeable porous filter materials can be used for dedusting.
