Both pipettes and burettes are laboratory applications utilized for exact liquid measurement. the key distinction is pipettes are used for smaller volumes of liquid, Whilst burettes are employed for greater volumes.
Improved Safety Measures:: compared to traditional measuring cylinders, pipettes jump out to be a safer option, especially when working with hazardous substances.
These would not have an adjustment knob for chaining the volumes. These pipettes transfer an equal quantity of samples each and every time.
