Glass Syringes

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.

Luer Lock Fitting Connection

Syringe

Syringes with a luer lock connection secure onto a luer lock needle with a twist. They have a stronger connection than luer slip syringes.

Syringes with PTFE Piston—Syringes with a piston are ideal for use with gases because the piston creates a leak-free, gastight seal against the barrel. They’re also great for liquids that don’t fully mix—the piston’s seal 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.

Autoclavable—Autoclavable syringes must be disassembled before autoclaving. Keep in mind that repeated autoclaving can reduce their lifespan, so chemical sterilization is preferred.

Luer Slip Fitting Connection

Syringes without a piston resist wear and are nearly frictionless to operate.

Syringes with a luer slip connection use friction to hold a luer lock needle in place. Since they don’t have a locking mechanism like luer lock syringes, their connection isn’t as strong.

Threaded Fitting Connection

Syringes with a threaded connection are about the same in terms of connection strength as a syringe with a luer lock connection and have a stronger connection than luer slip syringes.

Fixed 304 Stainless Steel Needle

Syringes without a piston resist wear and are nearly frictionless to operate.

Fixed syringes come ready to use with a needle permanently attached. They’re often used with syringe pumps. However, once the needle bends, breaks, or clogs, the entire syringe has to be replaced. They also aren’t autoclavable.

Precision-Dispensing Glass Syringes

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.

Micropipettes

These fixed-volume micropipettes dispense a small amount of liquid for speedy, routine dispensing jobs. Plunger tip is color-coded by capacity. They require a tip (sold separately).

Fixed-Volume Pipettors

Good for speedy, routine dispensing jobs, these pipettors use air displacement to dispense the same volume every time. They’re more comfortable to hold than standard pipettes—a finger rest anchors to your hand so they’re easier to use one-handed. Press the ejection button to release used dispenser tips without touching them or changing your grip. Use these pipettors with universal-fit pipette tips. For easy identification, they’re color-coded by capacity.
