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.
