Gas syringe A-2, 10 mL RN, .029 inch x .012 inch x 2 inch, bevel open end, luer lock

Syringe with Luer Lock Needle - Designed for externally threaded glass containers

All the advantages of the A series syringe plus a push button valve which allows instantaneous injection. Ideal for small liquid samples containing low-boiling components.

Allows sample storage
in 25 μl syringes
Particularly useful when handling small liquid samples containing low-boiling components, usually lost through evaporation using ordinary syringes. In addition to sample storage capability, the push-button valve allows for pre-pressurization of samples prior to injection. By pre-pressurizing the sample gas to match or exceed the pressure in the chromatograph, the sample can be flushed instantaneously into the column as a ‘slug’. The result is better resolution.

Always leak-tight
The A-2 uses a special needle and needle connector designed specifically for chromatography and other analytical sampling. Significantly lower dead volume than conventional style Luer connectors.

Features a push-button valve, which allows sample storage to 250 psi in syringes as small as 25 μl. Available for use in a variety of containers including tapered, internal and external threaded containers, and for use with vacuum bulb or line.
