Aliquoting and Multi-Dispensing: Electronic pipettes are employed for aliquoting reagents into numerous doses, facilitating exact and constant distribution of small liquid volumes, lowering handling time and glitches.
pH Measurements: utilized in pH measurements exactly where altering sample pH is critical, pipettes permit controlled addition of acidic or primary options for pH adjustments.
the very best quality pipettes are termed style A pipettes. Other people are named as kind B, C, D and E respectively. kind D & E are bad excellent pipettes.
The safety regulations incorporated the statement: "by no means pipette by mouth KCN, NH3, sturdy get more info acids, bases and mercury salts".
