Sturdy, reliable, and easy to use

Sturdy and reliable, extremely simple to set up and use - and surprisingly affordable. Liquid crystal displays (LCDs) prompt you through set­up: First, select syringe from table stored in the pump's memory and displayed on the LCD. Next, enter the volume to be dispensed. Finally, 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 realtime readings using both parameters and values for clearer, mistake-free readings.

Features

A second syringe mount has been added to the basic SP100i, with both syringes activated by a single pusher block for simultaneous infusion and withdrawl. This inexpensive two-syringe pump combines precision and simplicity with outstanding ease of use and durability. Its features include automatic volume control and shutoff, simple menu-driven setup: dispense volume, dispense flow rate, syringe diameter (selected from displayed table), Last settings stored in permanent memory, and continuous dispense volume display.
