乐畅奇KDS 270连续循环注射泵
KDS270 Syringe Pump
The KDS270 can hold up to four syringes and can cycle continuously back and forth in a push-pull action. As two syringes are infusing, two 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 3-way valves the pump can empty and refill syringes for a continuous dispense.
乐畅奇KDS270最多可放置4个注射器，并能连续来回循环推拉。两个注射器注入，两个注射器以同样的速率抽取。达到设定容量时自动改变方向，开始下一次循环。通过使用三通阀，泵可以排空和重新关注注射器，实现连续分配。
