The syringes feature a PTFE plunger tip, stress-formed by a special process to ensure a leak-tight seal. The self-lubricating plunger tip stays smooth for the life of the syringe, with none of the seizing or residue buildup associated with conventional all-metal plungers.

• Removable needles
• PTFE plunger tip
• PTFE-sealed needle
• Low dead volume
• Crisp clean graduations

Small liquid samples with low-boiling components are not lost through evaporation, as often occurs with ordinary syringes. The positive rear stop prevents plunger blowout at elevated pressures.
