- Gastight sample locking
The sample lock incoporates an on/off valve needle. Ideal for sample collection and storage, pre-pressurization of gaseous samples for GC analysis and sample spiking. 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.
