Cobetter Lifemeta SF single-use check valve is mainly used to control the direction of fluid flow. The diaphragm sealing design effectively prevents fluid backflow, reducing the risk of material contamination.

In the non-working state, the diaphragm of the check valve is in the closed state. Its two ports use a hose barb design, which is convenient to connect tubing and realize liquid transfer.


• Polypropylene main body with silicone septum

• The diaphragm opening pressure is low, basically 0 kPa

• Ensure directional flow of liquid and prevent backflow

• Polypropylene and silicone material, with a maximum pressure resistance of 5 bar

• Alleviate the problem of air trapping

Q: The material of the film-coated tee pressure gauge?

The film-coated tee pressure gauge does not require a gasket and is made of HDPE+KA film. It cannot withstand steam sterilization.

Q: Will a single-use system that has been irradiated have any impact on the product? Can irradiation residues be detected in the irradiated items?

No. The irradiation dose is validated to ensure sterilization effectiveness. Moreover, the irradiation process only involves energy absorption and does not involve direct contact with the radiation source. Therefore, there are no issues of irradiation residues in the disposable system.

Q: The clamp does not tighten or fit. What should I do?

This may be due to the thickness of the TC connector. It is recommended to use Cobetter's clamp with Cobetter's TC flange.
