Electronic pipettes typically reduce human variance, improving accuracy and reproducibility.Īutomation pipettes: Automation pipettes are similar to electronic. The user only has to press a button to start aspiration, liquid dispensing or tip ejection. User is able to set volume and use a plunger to aspirate and dispense liquid.Įlectronic pipette: The basic operating principle of electronic pipettes is the same as with mechanical, but all actions are handled by an electronic system inside. These pipettes always use disposable pipette tips.

Manual pipettes aspirate and dispense liquid with piston system driving air cushions. Mechanical / manual pipettes: A workhorse of most laboratories and widely used in various applications. Volumetric pipettes rely on users for measurement of volume and require a separate device for aspiration and dispensing - such as the Midi Plus pipette controller. Their volumes generally range between 1mL - 100mL. Volumetric pipettes: Volumetric pipettes are typically made of plastic or glass and have graduation marks.
