Products Description
This product is a newly upgraded sealing solution designed specifically for laboratory sample tubes, providing a safe seal to eliminate evaporation and ensuring that the needle does not push the diaphragm down and fall into the bottle during the sampling process. PTFE and silicone membranes with adhesive properties. Perfectly combine the lid and diaphragm to provide stable and reliable sealing performance.
The biggest highlight of our bonded cap is guaranteed analytical purity. Our professional bonding process introduces no extra contaminants, effectively preventing any substances from leaching out of the cap and diaphragm components into laboratory samples, which ensures accurate and pollution-free test results.
