Standard Infuse/Withdraw Harvard Pump 11 Plus Advanced Single Syringe with Dual RS-232 Syringe Pumps

The Pump 11 Plus family of pumps are our more basic pumps, but provide the precision flow that Harvard Apparatus pumps are known for. Select from either 1 or 2 syringe models and from basic infusion only or the more advanced infuse/withdraw models. The infuse/withdraw models also have RS-232 communictions.

• NEW brighter display: easier to read and use
• NEW volume dispense feature
• Single or dual syringe models available
• Small, compact size

Harvard Apparatus’ Syringe Pump 11 Plus combines smoother flow and updated features to create a high performance syringe pump with a basic syringe pump price!

Bright Display and Easy-To-Use Interface
A new, two-line 16 character vacuum fluorescent display and six membrane keys make this a powerful, easy-to-use syringe pump. Only two entries are required to start pumping; Syringe ID and flow rate. The flow rate can be changed while the pump is running.

Two Modes of Operation,
Constant Flow Rate & Volume Dispense
The new Pump 11 Plus will operate continuously in RATE mode or accurately dispense a specific amount of fluid in VOLUME mode.

Select from two different models. The standard Pump 11 Plus model has the following features:
• Infusion Only
• End of Travel Limit Stop
• Anti-Siphon Bracket

The Pump 11 Plus Advanced model has the same features as the standard model, but also includes:
• Infusion/Withdrawal
• Dual RS-232 Communications

Both models are available with either a single syringe configuration or dual syringe configuration. Select the pump that best fits your application.

Non-Volatile Memory
New micro-stepping pump profiles deliver very smooth and consistent flow over the entire flow rate range. These pumps now feature non-volatile memory. The pump remembers its last syringe size, flow rate used and configuration settings. An advanced universal power supply means there is no need to change AC line switches, fuses or wires.

The new Pump 11 Plus will operate on any AC line voltage from 95 VAC to 240 VAC, either 50 or 60 Hz. The new Pump 11 Plus offers the same power failure mode as our PHD 22/2000 syringe pump series. In a power failure the pump can either Resume or Stop pumping when power is returned.

The Pump 11 Plus motor will not shut itself off in case of overload, rather it will remain in a stalled position with no damage. An adjustment collar on the guide rod prevents the syringe plunger from hitting bottom.

CE Mark Approved
The new Pump 11 Plus meets all relevant European EMC and Safety requirements for laboratory equipment..
