Product Introduction

★ Gas aluminum foil sampling bag: The material of the PTFE through valve is polytetrafluoroethylene (PTFE). The PTFE straight through valve adopts a self sealing structure, which is tightly sealed, without rubber seals in contact with the gas inside the bag, and does not contaminate the gas sample. The air duct of the PTFE straight through valve is perpendicular to the plane of the bag film, with an outer diameter of 6mm. Rotate the handle to make it perpendicular to the plane of the film, and the valve will open; Rotate the handle another 90 degrees to make it parallel to the membrane plane, and the valve will close. The PTFE straight through valve switch is convenient, fast, and tightly sealed. A sampling cap can be installed on the upper end of the PTFE straight through valve's gas tube, and the sampling cap is equipped with a silicone pad for needle injection and sampling. The catheter can be inflated, deflated, and vacuumed. Suitable for filling inorganic and organic gases that are non corrosive to polytetrafluoroethylene. Due to the fact that the gas sample inside the bag does not come into contact with the silicone rubber gasket and will not be contaminated, the PTFE straight through valve interface can be used for the collection and storage of low concentration gas samples with high analytical accuracy requirements. This interface gas sampling bag has obtained a national patent.

★ Fluorine containing gas sampling bag: This product has excellent corrosion resistance and is suitable for strongly corrosive gases. Corrosive gases such as sulfur dioxide, hydrogen sulfide, nitrogen dioxide, etc. It can effectively prolong the storage time of trace corrosive gas components in the sampling bag.
