BT301S Suitable Pump Heads and Tubings, Flow Parameters

Drive type Pump head Ch           Tubing size Flow rate per channel (mL/min) 
BT301S YZ15 1,2 13# 14# 19# 16# 25# 17# 18# 0.005~1495
YT25 1 114#116#15#24#35#36# 0.024~1750

Above flow parameters are obtained by using silicone tube to transfer pure water under normal temperature and pressure, in actually it is effected by specific factors such as pressure, medium, etc. Above for reference only.
