Hydrophobic PTFE Membrane Capsule Filters (PP Housing)
Engineered for gas/liquid separation in humid environments, our hydrophobic PTFE membrane filters feature advanced water-repellent properties (＞150° contact angle) combined with chemical-resistant PP housing, solving moisture ingress issues in bioreactors and solvent tanks. -
Pharmaceutical Grade Hydrophobic PTFE Pleated Filter Cartridge | Sterilizing Grade, FDA Compliant
Our sterilizing-grade hydrophobic PTFE pleated filter cartridge is engineered for critical pharmaceutical applications requiring absolute bacterial retention (>99.99% efficiency at 0.1μm). Compliant with FDA 21 CFR Part 211 and EU GMP Annex 1, it ensures bioburden-free processes in sterile water systems, fermentation, and aseptic filling.
✅ Zero Risk of Microbial Contamination
Hydrophobic PTFE membrane repels water while allowing gas/vent filtration, preventing biofilm formation.
✅ Validated for Sterilizing Grade
Passes ASTM F838-15 bacterial challenge tests, supporting integrity testing (e.g., bubble point, diffusion flow).
✅ Customizable Solutions
Available in 5″, 10″, 20″, 30″ lengths with options for single/double open ends, 316L housings, and validation documentation.✅ Global Compliance
Certifications: ISO 90001, USP Class VI, FDA on file. -

High Performance Depth filter sheets
H Series papers are manufactured using higher quality fillers with a higher specific surface area.
H Series filter papers are designed for difficult filtration applications, high viscosity liquids and high solids content. They have a high filtration efficiency with particle sizes as small as 0.2µm, ensuring filtration accuracy at higher throughputs. Internal voids and filter aids enable the board to effectively retain contaminants such as micro-organisms and ultra-fine particles in liquids. This filtration can be used as fine filtration to reduce microbial counts, pre-filtration for protective film filtration, and haze-free filtration of liquids prior to storage or filling. -
Polyethersulphone (PES) membrane Filter Cartridges For fine, clarifying, biological filtration of liquids
NSS serious membrane filters are produced on the basis of the one-layer hydrophilic asymmetric polyethersulphone membrane with the micron ratings of 0.2-0.8 μm. The special structure of pores ensures uniform clogging of the membrane and makes it much easier to filter viscous liquids. Increased overall porosity of the membrane combined with high thermal and chemical resistance ensures high flow rate and reliable removal of mechanical particles, bacteria, suspended matters and colloids from liquids in a wide range of pH. Minimal absorption of the polyethersulphone membrane makes NSS serious cartridge the best choice for application in the processes of filtration of albumin containing solutions and biological liquids, especially in biopharmaceutical industry and beverages industry.

Filter integrity tester Integtest V8.0
Filter Integrity Tester —— Integtest seriesDongguan Puno Filter Integrity Tester Integtest series are special instruments of integritytesting for sterile filtration membrane and filter system, where the testing method and instrumentdesign fully meet the requirements for relevant laws and regulations in GMP, EP, FDA and USP.◎ Regulatory requirements1. Chinese GMP and EU EP have made specific provision for the integrity testing of sterilefilter on the test method, where the commonly used methods include bubble point test, diffusionflow test or pressure holding test. GMP regulates that the test is required after the use of sterilefiltration. EP regulates that the test is required before and after the use, and at the same time EPregulates that the critical gas and air filter must be confirmed after use, while other filters must betested on a regular basis.2. According to Drug Manufacturing Quality Management Standard (revised in 2010) Article310, two appendices of Computerized System and Confirmation and Validation are now issued,as the supportive documents for Drug Manufacturing Quality Management Standard (revised in2010), effective as of December 1, 2015.3. The requirements for electronic records and electronic signatures as specified in 21 CFRPart 11. -
