PIPETTING MODULE

How to control the pipette ?

In our system, we need to pipette automatically different volumes to execute our biological process.

The solution we chose is to use an electronic pipette Biohit e10. The main advantage is that after removing the cap of the pipette, we can solder wires to the electronic card to control the different buttons of the pipette and it will work by itself!

- The button functions are:

- Select (mode)

- Enter

- Up (to select the volume for isntance)

- Down

- Tip Ejection

- Start (controls the piston movements)

To make the pipette work, we need a power supply of 5 Volts and 1.5 Ampers at least. Wires are connected from an Arduino card (microcontroller) to the buttons to control them later.
