Beaker is a common laboratory glassware used for holding and mixing liquids, but it's not electrically powered.
Perhaps you're thinking of an electric stirrer or a heating plate? These are common pieces of equipment used in microbiology labs:
* Electric stirrers are used to mix liquids and solutions. They can be used to dissolve substances, create homogenous mixtures, or suspend particles in a liquid.
* Heating plates are used to heat solutions and cultures. They are often used in conjunction with a stirrer to create a heated and agitated environment for growth.
In addition to these, other common equipment used in microbiology that might have an electrical component include:
* Autoclave: A pressure cooker used to sterilize equipment and media.
* Incubator: A device used to maintain a specific temperature for microbial growth.
* Microscope: Often has an electric light source for illumination.
