Product Description
Seal a vial and still reach its contents with a syringe whenever you need to. The push-pull valve closes the vial completely between uses, making it ideal for sealed tube reactions, long-term storage of standards and periodic addition of reactants without exposing samples to air.
This listing is for Kimble catalog number 749110-0022: Mininert Valves, Modified GPI Thread 20-400, Size 22. The valve uses a color-coded push-pull stem, green for open and red for closed, and a septum that prevents leakage while a needle is inserted. Two versions are offered: size 21 with a modified GPI 13-425 thread and size 22 with a modified GPI 20-400 thread. Vials are not included. Mininert is a trademark of Dynatech. LIGHT LABS supplies the complete DWK Life Sciences line, including Kimble, Wheaton and DURAN labware.
