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.

Filter out contaminants when drawing in and dispensing from syringes with a luer lock connection.

PES filters are the easiest to push samples through. They have strong, tight fibers that won't get clogged or break as easily as standard filters. Use them with large volumes and samples with plenty of debris.

PTFE filters have better chemical resistance than nylon filters.

Glass filters are often used before plastic filters to capture larger particles.
