  • Page 20: Mounting A Syringe

    Mounting a Syringe Before mounting a syringe on the CETONI Nemesys M, it must be configured and selected in the software. The procedure is described in the software manual. For this you need the Volume (Scale Volume), the nominal stroke (Scale Length) and the maximum stroke (Piston Stroke).
  • Page 21 Scale Volume Scale Length Proceed as follows to mount a syringe on the CETONI Nemesys M Use the software to move the piston holder to the foremost position. Push the syringe piston into the syringe as far as it will go and screw the star nut onto the syringe by six to seven turns:...

    For easier bleeding of the syringes it is often helpful to operate the syringe pump upright. To increase the standing safety in this case, the CETONI Nemesys M is equipped with a stand foot. This is magnetically located in a recess on the side. Take it out, turn the module upright and put the stand foot back in place rotated by 90°.

  • Page 28: Accessory Port

    The accessory port allows the integration of accessories such as valves and pressure sensors. To do this, plug the cable connector of the accessory component into the socket of the CETONI Nemesys M until it engages. Make sure that the plug can only be inserted when the coding nose is pointing upwards.
