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.
