Product Description

• The A-2 features a pusbutton valve, which allows sample storage to 250 psi in syringes as small as 25 µl. This is useful with small liquid samples containing low-boiling components which would be lost through evaporation using ordinary syringes.
• The positive rear stop (in 250 µl and larger sizes) prevents plunger blowout at elevated pressures, protecting against sample loss or operator injury. In addition, the A-2 syringe has all the standard Pressure-Lok features such as a PTFE plunger tip, PTFE-sealed needle, and ultrasmooth bore. Replacement components are available for easy repair.
