500HL Syringe Pump by Teledyne ISCO

Manufacturer Teledyne ISCO
The 500HL pump handles a broad range of fluid delivery and dispensing applications in locations where equipment must be rated for Class 1, Div 2 (gas groups ABCD). Flow rate is settable from 1microliter/minute up to 122 ml/minute, with a 3750psi (258 bar) pressure limit. Refill takes only about 4 minutes. The programmable HL controller gives you instant access to menu screens - even when the pump is running – to enable on-the-fly changes in limits and other operating parameters. An optional ext...

The 500HL pump handles a broad range of fluid delivery and dispensing applications in locations where equipment must be rated for Class 1, Div 2 (gas groups ABCD).

Flow rate is settable from 1microliter/minute up to 122 ml/minute, with a 3750psi (258 bar) pressure limit. Refill takes only about 4 minutes. The programmable HL controller gives you instant access to menu screens - even when the pump is running – to enable on-the-fly changes in limits and other operating parameters. An optional extension cable for remote operation lets you locate the pump up to 50 feet from the controller.

Wetted materials are compatible with most aqueous and organic liquids, corrosive solutions, heated fluids, liquefied gases, viscous fluids, or slurries and pastes. If needed, optional materials such as Hastelloy C-276 are available on request.
