Model 260 D Syringe Pump from Isco, Inc.

For Supercritical Fluids
 
The 260D syringe pump is 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. Dual-pump systems can provide the capability to meter solvent modifiers into the flow stream, or to deliver non-stop continuous flow.

The 260D is also used for a variety of other applications matching its flow and pressure specifications. For applications requiring pressures up to 10,000 psi and/or greater low-flow precision, see the 100D models.

Standard Features
  • 260D pump has 1/8" Valco fittings for easy connection in process and pilot-plant plumbing.
     
  • Integral button-style pressure transducer in cylinder cap assures excellent stability and repeatability.
     
  • Rugged single-ratio drive train has auto-lubricating gears to assure long life and low maintenance.
     
  • Each Isco D-Series syringe pump is bench tested at the factory. All pumps are CE compliant and certified to UL 3101 and EN 61010-1 standards.
     
  • Cylinder wash system protects the seals from deposits.
     
  • Exclusive "Smart Key" controller. All Isco D-series pumps use the same controller that can operate any three pump modules, either independently or together. Operating modes include:
    - Single pump independent constant flow or pressure
    - Single pump flow - or pressure - ramp programming
    - Single pump dispensing
    - Dual pump continuous constant flow or pressure
    - Dual pump concentration gradients
    - Three-pump configured systems
     
  • RS-232 serial interface for computer control or monitoring of operating parameters.
     
  • Redundant safety is designed in. All D-Series pumps have mechanical and electrical fail-safes, in addition to the factory default or user-set limits.
     
  • Corrosion resistance. Nitronic 50 - the standard material for cylinders, pistons, and caps - is an austenitic stainless steel with outstanding strength and corrosion resistance.
     
  • Standard seals are heavy-duty, graphite-impregnated Teflon, providing very long life under harsh operating conditions.

Applications
  • Supercritical Fluids techniques including extraction, reaction, and chromatography
     
  • Precision fluid feed in small-scale experiments
     
  • Specialized chromatography and other analytical applications requiring extremely low flow noise and ml/min range flows.
