Final answer:
Thermo gel appliances should be cleaned promptly to prevent the gel from solidifying. Cleaning should not be delayed for more than a few hours.
Step-by-step explanation:
When dealing with thermo gel appliances, it is important to clean them promptly to prevent the gel from solidifying. The cleaning should not be delayed for more than a few hours. If left for too long, the gel can form solid aggregates that are difficult to remove.
An example of a thermo gel appliance is a gel electrophoresis apparatus used in molecular biology. After running a gel, if the gel is left for more than a few hours, it can become solid and not easily removable.
In order to avoid this, it is recommended to clean the appliance within two hours after completing the experiment.
