Digital lab scale peristaltic pump

Drive Model : BT100M


0.0015-36 ml/min per channel

Related Application

CR Peristasltic pump BT100M/DG series with flowrate of 0.0015-36 ml/min. Multiple pump heads can be cascaded. Suitable for high precision and micro flow application .
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 3 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.

Advantage of CR peristsaltic pump.
CR Peristaltic pump are easy to maintenance
replaceable tubes allow you to switch from one liquid to another in the shortest amount of time.
No need to rinse and disassemble after the flushable product, you only need to replace the peristaltic pump tubing
CR Peristaltic pump with high precisio
The calibration function can ensure the filling accuracy for each dose .The suckback function prevents liquid (reverse): in the dispense mode, after the end of the direct cycle, the return stroke is initiated to prevent the liquid from flowing out of the pump tube during the stop.
CR peristaltic pump are non-pollution: the fluid only contacts the pump tube and does not touch the pump body;
CR Peristaltic pump is Versatility
CR peristaltic pump can be used with a variety of products and can be used in a variety of industries.
CR peristasltic pump are easy to work
After the power is turned off and on, the control system maintains the current settings (pump head  tubing model and other parameter ).
CR peristaltic pump with good sealing: It has good self-priming ability and can be idling to prevent backflow.
CR peristaltic pump with Low shear: ideal for conveying shear sensitive, aggressive fluids



The micro flow peristaltic pump model BT100M can be work with DG series pump head .

The DG series micro-flow multi-channel peristaltic pump head is a separate card installation and special hose; the pressure tube gap can be fine-tuned to adapt to different wall thickness hoses. Designed for small flow, multi-channel fluid delivery.

Channel number means How many tubes you want to run in the same time .

Noted : There will be some error between each channel. If you can not accept error between each channel pls order carefully.

Roller number : More roller means less pulse and flow

For the channel number the options as above
