Digital liquid dispensing peristaltic dosing pump  -  BT300FJ

The simple design provides economical choice for you, that guarantees the quality and saves the cost at the same time.Two kinds of operating modes, transferring and dispensing, may achieve the transfer function as the basic type peristaltic pump, and also achieve the dispensing function as the dispensing type peristaltic pump. 
Needn’t purchase the time distributor in addition, reducing the accessories and saving the cost. 
Install external control module free to achieve start stop of external control, and coordinate with filling machine to work. 
Widely used in multichannel transfer fluid in batch.

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.
