Hydrophilic PTFE Filter Cartridge for Liquid Filtration
价格范围：$2.00 至 $7.00
Hydrophilic PTFE filter cartridges are precision liquid filtration elements designed for demanding industrial and laboratory applications. Made from high-quality hydrophilic PTFE membranes, these cartridges ensure excellent chemical compatibility, fine particle retention, and minimal extractables, making them ideal for aqueous solutions, pharmaceutical liquids, and ultra-pure water systems.
| Filter Media | Hydrophilic PTFE |
|---|---|
| Micron | 0.1um, 0.22um, 0.45um, 0.65um, 1um, 5um, 10um |
| length | 10 inch, 20 inch, 30 inch, 40 inch, 60 inch, 70 inch |
| End Cap | DOE, 222/Fin, 222/Flat, 226/Fin, 226/Flat |
Hydrophilic PTFE filter cartridges are engineered for high-performance liquid filtration in industries requiring ultra-clean fluids. The hydrophilic nature of PTFE allows water and other polar liquids to pass easily, while efficiently retaining sub-micron particles, microorganisms, and colloidal impurities.
These cartridges are ideal for pharmaceutical, biopharmaceutical, electronics, food & beverage, and laboratory water filtration applications. The pleated PTFE membrane provides a large filtration surface within a compact cartridge, reducing system downtime and maintenance frequency.
The cartridges are designed for use in standard housings and come in multiple end cap configurations to fit most industrial and laboratory filtration systems. The robust PTFE material ensures chemical resistance across a wide pH range and long-term mechanical stability, even under repeated sterilization cycles.
Available in standard sizes such as 10", 20", 30", and 40", these cartridges deliver consistent filtration efficiency and are suitable for critical liquid filtration processes where product purity is paramount.
