PTFE Pleated Filter Cartridge - 100% Rinsed with Ultrapure Water

The PTFE Pleated Filter Cartridge has undergone complete integrity testing such as bubble point and diffusion flow, and has been rinsed with pure water (the electronic grade filter cartridge is rinsed with ultrapure water). At the same time, it meets the requirements of biocompatibility and endotoxin control indicators in the pharmacopoeia (USP), and is suitable for various industries such as water treatment, chemical industry, electronics, industry, textile, food, and pharmaceuticals. The company provides hydrophobic PTFE membrane filter cartridges (high porosity, high flux, long life) and hydrophilic PTFE membrane filter cartridges (filtering of various strong acid and alkali solutions without wetting). The company develops products finely for different scenarios to meet the different needs of customers.
