40mm 0.2 micron PTFE Hydrophobic Bactria Filter For Suction Unit
Aspirator
The bacteria filter is constructed with a polytetrafluoroethylene
(PTFE) membrane, offering excellent resistance to both organic and
inorganic chemical corrosion, as well as inherent hydrophobicity.
It is widely used in biotechnology, pharmaceutical industries,
laboratories, and any process requiring sterile venting. The
product is lightweight, safe, and reliable, with no risk of tube
kinking that could obstruct ventilation.
Product Features:
- Naturally strong hydrophobicity, oxidation resistance, and
resistance to organic/inorganic chemical corrosion
- High flow rate and low extractables
- Lightweight design for easy installation and removal
- 100% integrity tested
Applications:
- Sterile venting of culture vessels and CO₂ incubators
- Sterile venting of liquid culture media
- Sterile venting of small-scale fermenters
- Sterile venting of storage tanks
- Autoclave venting
- Gas particulate removal
