The new “µl” Pump Module is a low cost, highly precise, single syringe infuse/withdraw pump capable of low to moderate back pressures. It is available in one version only and will hold one syringe of any make from 0.5 µl to 1 ml. The inside diameter of the syringe and desired flow rate are entered via the RS-232 serial port, and the internal microprocessor drives a precision stepper motor to produce accurate fluid flow. This unit is designed to operate inside an enclosure, cabinet, or on top of a bench. The board may be removed for “remote” operation.

Two Modes of Operation - Constant Flow Rate and Volume Dispense
The “µl” Pump Module will operate continuously in RATE mode or accurately dispense a specific amount of fluid in VOLUME mode. When starting the pump, RATE mode will be the default mode. To operate in Volume mode, set a target volume and the pump will change modes to suit desired operation. This is the safest way to use the “µl” Pump Module. The pump will automatically stop when target volume is dispensed.

Smooth Flow
New micro-stepping pump profiles deliver very smooth and consistent flow.

Nonvolatile Memory
The pump remembers it?s last syringe size, flow rate used and configuration settings in its non-volatile memory.

Location Requirements for the Syringe Pump
• A sturdy, level, clean and dry surface
• Minimum of one inch (2.5 cm) clearance around
the pump
• Adequate power supply
• Operating temperature 0° to 35°C (32° to 95°F)
• Relative humidity 20% to 80%

Protecting Small, Fragile Syringes
The “µl” Pump Module will hold microliter size syringes down to 0.5µl size. These small syringes have fine wire plungers that may be damaged if allowed to bottom out. The “µl” Pump Module is equipped with adjustable limit switches on the bottom side of the mounting plate. Make sure to adjust the limit switches to prevent damage to small syringes.
