Hamilton Company's SampleLock syringes allow you to collect, store, transport, and analyze liquid or gaseous samples without the danger of evaporative loss or environmental contamination. Common applications for Sample-Lock syringes include headspace and environmental sample collection and storage, pre-pressurization of gaseous samples for GC analysis, and sample spiking. Syringes are available in sizes ranging from 50 µL to 100 mL. A positive rear stop on SampleLock syringes (250 µL to 100 mL) prevents plunger blowout and loss of sample. Optional male and female luer and male luer lock adapters thread onto the SampleLock valve making the syringe compatible with a multitude of connectors and fittings.
