Introduction
Theory of Operation:
The new Pump 11 is designed as a low cost, highly precise, single syringe infusion pump
capable of low to moderate back pressures.
The pump comes in two versions; one to hold one syringe of any make from 0.5 µl to
60ml and a second to hold two syringes of any make from 0.5 µl to 10 ml. The diameter of the syringe(s) is entered via the keyboard and the internal microprocessor drives
a precision stepper motor to produce accurate fluid flow.
Non-volatile memory stores the last syringe diameter and flow rate along with other
configuration data.
The “Power Failure Mode” can be set to either turn the pump off in the event of power
failure or to resume pumping when power resumes.
Features:
Bright Display and Easy-To-Use Interface
A new, two-line 16 character vacuum fluorescent display along with six membrane keys
make this a most attractive but powerful, easy-to-use syringe pump. Only two entries
required to start pumping; syringe Inside Diameter (mm) and pumping flow rates. The
Flow rate can be changed while the Pump is running.
Two Modes of Operation, Constant Flow Rate and Volume Dispense
The new Pump 11 will operate continuously in RATE mode or accurately dispense a
specific amount of fluid in VOLUME mode.
Smooth Flow
New micro-stepping pump profiles deliver very smooth and consistent flow.
Nonvolatile Memory
The pump remembers its last syringe size, flow rate used and configuration settings.
Universal Power Supply
No need to change AC line switches, fuses or wires, the new Pump 11 will operate on
any AC line voltage from 90 VAC to 240VAC, either 50 or 60 Hz.
Power Fail Mode
In a power failure the Pump can either RESUME or STOP pumping when power is
returned.
CE Mark Approved
The new Pump 11 meets all relevant European EMC and Safety requirements for laboratory equipment.
