Teledyne ISCO D-Series single-pump systems consist of a controller and pump module. The piston-driven pump module uses a single speed gear train. Nitronic 50 is the standard material for cylinders, pistons, and caps, with Hastelloy and other alloys available for even greater chemical resistance. Standard seals are graphite-impregnated Teflon, providing long life under harsh operating conditions, with optional seals available for special applications. 

The D-Series controller offers many different operating modes and features, and we can also customize the software to your specific application on request. The standard operating modes are: 

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

1000D Syringe Pump

The 1000D is the largest of the ISCO D-series pump modules, with 1-liter nominal cylinder capacity. It delivers precise, positive, pulseless flow over a range of 0.001 mL/min to 400 mL/min, at pressures from atmospheric to 2,000 (psi) bar. Improved displacement resolution on this model gives finer control over motor movement. Coupled to our patented servo circuit, this means the 10​​00D can deliver excellent flow accuracy without the need for external flow meters.

500D Syringe Pump

The 500D is ideal for a wide range of chemical feed applications requiring flow rates up to 200 mL/min at pressures up to 3,750 psi. With its 500 mL cylinder capacity, this pump can deliver a precise 500 mL/min for over 8 hours on a single fill. For non-stop continuous flow, see dual pump systems with a choice of valve packages.

260D Syringe Pump

The 260D was the first ISCO D-Series pump module, and our first syringe pump designed specifically for refilling under high pressure and pressure programming to handle supercritical fluids. With pressure control to 7,500 psi (517 bar) and a flow rate range from sub-microliter to 100 mL/min, the 260D offers exceptional versatility for almost any type of R&D or method development with supercritical CO2 and other fluids.

100DX Syringe Pump​​

The 100DX was developed to meet the demand for a 10,000 psi pump with fast flow and refill for Supercritical Fluid Extraction. It has also found many other applications for jobs requiring the combination of high pressure and flow rate up to 50 mL/min. For the ultimate low-flow precision, we recommend the 100DM model.

65D Syringe Pump​

The 65D is our best pump for very high pressures or very low flow rates.
