These syringes are ideal for Purge and Trap applications because you can easily remove the syringe plunger and load water samples into the syringe barrel. You can add an internal standard or surrogate sample directly to your sample through the twist valve with a 10 µL syringe. You can also connect the sample syringe directly to the Purge and Trap valve via the integral male luer fitting.

Hamilton 5 and 25 mL Purge and Trap syringes were designed for the analysis of drinking water samples according to EPA purge and trap concentration techniques (see EPA methods 502.1, 502.2, 503.1, 524.1 and 524.2).
