Isco 260D Syringe Pump

260DOur most popular model for Supercritical Fluids

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. 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

• Cylinder wash system protects the seals from

• 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

- 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.


• 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.

Options and Accessories

• Hastelloy or Titanium construction

• Temperature control jacket (cylinder cooling for
filling with liquefied gas; thermal stabilization for ultra-low flow rates)

• High-temperature pressure transducers (for operation
with pump cylinder heated up to 200°C maximum)

• High-precision pressure transducers (0.1% linear

• Drivers for LabVIEW graphical programming software
from National Instruments

• Alternate seals optimized for special applications:
virgin Teflon for corrosive fluids, heavy duty reinforced for slurries and
viscous fluids, high temperature, low temperature, and UHMW polyethylene.
Choice of seals can be ordered factory-installed.
