A turn of the threaded plunger dispenses extremely small quantities—as small as a speck of dust. The fine threads on these syringes inch the plunger forward with every turn for a controlled, precise flow. You won’t accidentally push too much out with these syringes.

A glass barrel adds to their precision. It’s made to a tighter tolerance than a plastic barrel, so the plunger seals against the barrel and wipes it clean as it moves, dispensing every last drop. The glass barrel is also durable and resistant to chemicals, so it’s unlikely to wear or warp from your sample for a long, reliable life. Thanks to their precision, these syringes are often used for gas chromatography.

Attach a needle with a luer slip connection. Slide a needle onto the fitting and friction will hold it in place.

Before autoclaving these syringes, disassemble them. Keep in mind that autoclaving can reduce their lifespan, so chemical sterilization is preferred.

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.

Hold these syringes like a pencil and press the trigger for controlled dispensing without hand fatigue. The trigger is long enough that you can hold them far down the barrel and dispense with the same hand. This gives you extra control for precise dispensing in tight spaces. They have no piston, so they resist wear and are almost frictionless to operate.

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. They also have a high gas barrier to stop your sample from leaking out or getting contaminated by oxygen. Thanks to their precision, these syringes are often used for gas chromatography.

To attach a needle (sold separately), slide it in at the base and secure it with its locking nut. Made of stainless steel, needles have a smooth surface that limits friction. Needles with sharp beveled tip can be inserted without clogging or leaving a hole, making them ideal for puncturing septa lids.

These syringes can be disassembled for steam autoclaving. Keep in mind that autoclaving can reduce their lifespan, so chemical sterilization is preferred.

Pair these pipettes with a pipette pump to transfer measured streams of liquid. Each pipette has a color-coded band that indicates capacity so you can quickly differentiate one from the next.

Borosilicate and soda-lime glass pipettes withstand cleaning chemicals, so you can sterilize them for repeated use. They provide a clearer view over time than plastic pipettes because samples won't stain them. Soda-lime glass pipettes have extremely tight tolerances to dispense the same amount of liquid each time, keeping your measurements precise. Choose a pipette based on the capacity you need to dispense.

Pipettes with graduation marks let you accurately measure samples of various sizes with a single pipette.
