Syringe Pumps

Microprocessor-controlled syringe pumps for applications requiring high metering precision at low, pulse-free rates

Sturdy and reliable, extremely simple to set up and use — and surprisingly affordable. Liquid crystal displays (LCDs) prompt you through setup:
1. Select syringe from table stored in the pump’s memory and displayed on the LCD.
2. Enter the volume to be dispensed.
3. Enter the flow rate, press “start.”

It’s fast and simple. Your settings are permanently stored in memory — there’s no need to re-enter them each day. SP pumps feature preset rate and volume control. Just set the volume you want dispensed. 
Volume is tracked continuously on the LCD display. Then, when the preset volume has been dispensed, the pump shuts off automatically. The easy-to- read digital display provides real-time readings using both parameters and values for clearer, mistake-free readings. The SP200 Series pumps offer TTL and RS-232C interfaces and automatic shutoff under stall conditions.

Single-syringe infusion pump

SP100i
This inexpensive single-syringe infusion pump combines precision and simplicity with outstanding ease of use and durability.
● Holds any size syringe, 10 μL to 50 mL
● Automatic volume control and shutoff
● Simple menu-driven setup: dispense volume,  dispense flow rate, syringe diameter (selected fromdisplayed table)
● Last settings stored in permanent memory
● Continuous dispense volume display

Twosyringe infusion pump

SP101i
Developed especially for use in microdialysis experiments, these pumps produce very fine syringe movement. The modified SP100i gearing features a sixfold gearreduction compared tostandard
models, allowingpumping at muchsmaller flowrates. The SP101i is a dual barrel infusion onlypump.
● Holds two syringes, 10 μL to 10 mL

Two Syringe Infusion Pump

SP200i

This feature-laden two-syringe infusion pump combines a broad speed range and holds a wide range of syringe sizes to meet the requirements  of virtually any laboratory application.
● Holds two syringes, 10 to 140 mL
● Backlit LCD display
● Knob locks/unlocks drive block for effortless, drag- free adjustment
● Simple menu-driven setup: Syringe diameter (selected from displayed table), Dispense volume, Dispense flow rate
● Continuous dispense volume display
● Preset volume control and automatic shutoff
● Settings can be reviewed or changed during operation
● Optical encoder stall detection
● Choice of unit selection
● Last settings stored in permanent memory
● Built-in RS-232C interface for computer linking or
