Digital peristaltic pump -  BT300M

This product can be installed by YZ1515x,YZ2515x,, with flow rate from 0.007-1140mL/min. Flow speeds can be adjusted either by hand through switching knobs, instead of the traditional way of membrane keypad, which reduces obviously the failure rate, or by automatic control through the external controller interface, with three available modes: 0-5V, 0-10V and 4-20mA. Memory function is also available in the product in case of power off. Besides, switching knobs are designed clearly so that it is easy to operate for customers.

CR pump's silicon tube is the most commonly used material for peristaltic pump.
It provides the longest service life, and good chemical compatibility with aqueous and many organic solvents.
Its service life is about 150 hrs at 600 rpm and 825 hrs at 100 rpm.
It can usually be left running on experiments during weekends without much danger of rupture.
A fresh section of tubing should be pulled through the pump rollers before any running peristaltic pump is left unattended.
Silicone tubing can also be autoclaved a single time with a wet cycle without a significant reduction in its life.
High temperature and high pressure sterilization.

Function & characteristics:
1. Applicable pump heads: YZ1515x,YZ2515x.
