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.

Use these barrels with an air-powered dispenser to make repetitive dispensing easier on your hands.

Syringe barrels with a luer lock connection require a needle with a luer lock or luer slip connection to dispense contents.

Choose a black syringe barrel to dispense light-activated contents, such as adhesives.

Prevent static from damaging sensitive equipment as you use an air-powered dispenser. These barrels drain static away from your application, so they won’t pass along harmful charges. This makes them ideal for applying adhesives to electronics. Their black color keeps light-activated contents from hardening or curing before use. To dispense, you’ll need a static-control tip with a luer lock or luer slip connection.

Squeeze the bulb to dispense liquids one drop at a time. These droppers are also known as transfer pipettes.

Droppers with a dispenser box stay organized and protected when they’re not in use. The box has a hinged front panel for easy access to droppers.

Fine tip droppers help you dispense very small volumes. They’re often used with fast-flowing liquids, such as water and gasoline.

Wide tip droppers are good for thicker liquids, such as gel, syrup, and thin paste.

Bellows droppers have a large, accordion-shaped bulb that creates strong suction. They’re often used with viscous liquids.

Droppers with graduation marks have molded markings that won’t fade or wash off.

Sterile droppers are individually cleaned and bagged to avoid contaminating your sample.
