Syringe pumps

The Teledyne Isco syringe pumps of the D-series allow pulsation-free delivery in the range 1 µl/min - 408 ml/min against pressures up to 2068 bar.

Supercritical fluids, liquids and even highly viscous pastes can be pumped.

The syringe pump consists of a steel cylinder with movable piston and a control unit. 

Nitronic 50 is the standard material for cylinders, pistons and cylinder covers. Hastelloy is available for some pumps and results in even greater chemical resistance. The standard seals are made of graphite-impregnated Teflon, which ensures a long service life under harsh operating conditions, although optional seals are available for special applications.

The D-Series controllers offer many different operating modes. The standard operating modes are: 

  • Constant flow rate 
  • Constant pressure 
  • Flow or pressure programming 
  • External control

    In addition to precise delivery, Teledyne Isco syringe pumps can also be used for precise dosing. This is possible through an additional option, the Dispense Mode. It enables the user to set not only the flow rate exactly, but also the delivery rate. It switches off automatically as soon as the desired flow rate is reached. This function is highly interesting for dosing into a reactor, for example.
