MPPI-2 Pressure Injector

Source: Applied Scientific Instrumentation
MPPI-2 Pressure Injector
  • Front panel push button switch
  • External TTL input signal
  • Optional footswitch

    Linear adjustment of both pulse width and pressure gives precise control to meet all of your pressure injection needs.

    The MPPI-2 utilizes an external filter for reliability and ease of maintenance. The input pressure can be up to 100psi. The output pressure is adjustable from 0 up to 100psi.

    The MPPI-2 has an input for an optional Back Pressure Unit. This option precisely regulates leakage from the injection pipette. The BPU provides a convenient means of providing an adjustable, 0 to 15 psi, back pressure to the MPPI-2. The back pressure is applied to the injection pipette between injections to prevent back filling. Without the BPU the pipetter is at atmospheric pressure between injections.

    The Milli-Pulse Pressure Injector is a self contained device for producing gas pressure pulses to an injection pipette. The unit offers linear control of both pressure and pulse duration. The unit provides three convenient means of initiating the pressure pulse:
