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. The SP200 Series pumps offer TTL and RS-232C interfaces and automatic shutoff under stall conditions.

Up to four syringes of different sizes can be accommodated on this pump.
