The Hamilton® Gastight® SampleLock™ syringes allow you to collect, store, transport and analyze liquid or gaseous samples without the danger of evaporative loss or environmental contamination. An easy-to-use twist valve and a positive rear stop on SampleLock prevents loss of sample and plunger blowout.

SampleLock™ Syringes incorporate an on/off valve with removable needle. Use these syringes for headspace, environmental sample collection and storage, prepressurization of gaseous samples for GC analysis, and sample spiking. Not autoclavable.Use the sharp, curved, noncoring needle for septum penetration applications such as gas chromatography.
