Collect, transport, and store gas and liquid samples without worrying about evaporation or leaks. These syringes have a locking valve that keeps your sample secure. They also have a piston that creates a leak-free, gastight seal against the barrel.

With a glass barrel, these syringes have a long lifespan and aren’t likely to wear or warp from your samples. They have a tighter tolerance than syringes with plastic barrels, so they’re better at controlling small, precise flows. They’ll dispense all material inside with nothing left over—the needle sits exactly at the zero graduation mark, and the piston’s seal against the barrel wipes off any deposits from liquids. With no deposits, the plunger won’t get stuck while dispensing. The piston’s seal is also tight enough that the plunger won’t retract on its own, so you can dispense from these syringes in a slow, controlled manner. Thanks to their precision, these syringes are often used for gas chromatography.

To attach the needle, slide it in at the base of these syringes and secure it with its locking nut. Made of stainless steel, the needle has a smooth surface that limits friction. It’s also sharp and beveled so it can be inserted without clogging or leaving a hole. This makes it ideal for puncturing septa lids.

Made to a tighter tolerance than plastic syringes, these glass syringes are better at dispensing small, precise samples with little left over. They’re also durable and resistant to chemicals, so they’re unlikely to wear or warp from your samples, so they'll have a long, reliable life. Their precision makes them great for gas chromatography.

For quick and easy needle connections, choose between luer lock and luer slip syringes.

When precision is a top concern, choose between a threaded connection and a fixed needle. They’re both designed for the needle to sit exactly at the zero graduation mark, which minimizes leftover material in the barrel after dispensing.
