The SP210c from WPI can hold up to four syringes and can cycle continuously back and forth in a push-pull action. As two syringes are infusing, two other syringes are withdrawing at the same rate. At the end of the set volume the direction is automatically reversed and the next cycle begins. With the use of 2-way valves, the pump can empty and refill syringes for a continuous dispense. Holds four syringes, 10mL to 60mL each. With larger syringes the full volume may not be usable.
The easy-to-read digital display provides realtime readings using both parameters and values for clearer, mistkae-free readings. The SP200 series pumps offer TTL and RS232 interfaces and automatic shutoff under stall conditions.
