Before Use: Preparing the gel and samples

Use the plastic shutters to create buffer zones before you pour the gel.

Prepare the gel in a beaker. Once it is not too hot to hold for 30 seconds, add the safe stain and pour into the gel box. Add the comb. Allow the gel to cool. In the meantime, prepare your samples. Once the gel has solidified, remove the comb. Remove the shutters. Pipette the samples into the well and add the buffer.

 To start Gel Electrophoresis, set the voltage and click on the timer button. Note that since Bento Lab’s gel box is a mini-gel, 50V will be sufficient for most applications.

 The power supply will start, once the timer has been confirmed.
