General description

  • Twist valve locks the sample in the syringe
  • Positive rear plunger stop eliminates sample loss and plunger blowout at high pressures (not applicable to 1705 and 1710 models)
  • Connects to either male or female luer fittings by using an adapter
  • Male and female luer and male luer lock adapters thread onto the SampleLock valve making the syringe compatible with many connectors and fittings
  • All adapters have a Kel-F (CTFE) fluid path, with a port diameter of 0.039 in.
  • Internal standards can be added through the valve port into the sample contained in the syringe
