FAQ：
1.What are PVDF filter used for?
PVDF filters are commonly used for sterile filtration and clarification in various industries, including biopharmaceuticals, food and beverage, and microelectronics. They efficiently remove particles and microorganisms, ensuring product purity.
2.Is PVDF filter hydrophobic or hydrophilic?
PVDF filters can be both hydrophobic and hydrophilic, depending on the specific treatment applied during manufacturing. This versatility allows PVDF filters to be used in a wide range of applications, adapting to different liquid properties.
3.What is a capsule filter?
A capsule filter is a compact, self-contained filtration unit with a filter membrane enclosed in a capsule-like housing. It simplifies the filtration process, provides ease of use, and is often disposable. Capsule filters find applications in laboratories and industries for small-volume liquid or gas filtration.
4.What is the difference between PES and PVDF filter membrane?
PES (Polyethersulfone) and PVDF (Polyvinylidene Fluoride) are distinct filter membrane materials. PES membranes are hydrophilic, suitable for aqueous solutions, while PVDF membranes can be hydrophobic or hydrophilic. PVDF offers better chemical resistance and is often chosen for aggressive solvents and chemicals. The selection depends on specific filtration needs and compatibility with the substances being filtered.
