4ml Clear Glass Vial

Screw Cap Vials are universal. Screwing the cap applies a mechanical force that squeezes the septum between the glass rim and the cap. Screw caps form an excellent seal and mechanically hold the septum in place during piercing. No tools are required for assembly.

The 4ml screw neck glass vial produced by Aijiren is often used in Autosampler. The 4ml 13mm opening is convenient for automatic injection needle injection. The Cap has a center hole. PTFE and Silicone are compounded on both sides to ensure that one side of PTFE faces the reagent inside Vias, ensuring that the stability of the reagent is not destroyed.

1. The glass adopts high-quality borosilicate glass tube, with low free ion content, low expansion coefficient and very high chemical resistance.
2. The unique thread design can ensure the consistency of the seal.
3. Strict quality assurance provides dimensional consistency between batches.
4. It is suitable for autosampler of Aijiren, Shimadzu, Waters, CTC/Leap and other companies.
