2. Pipette - Wikipedia

   en.wikipedia.org/wiki/Pipette

   Pipettes come in several designs for various purposes with differing levels of accuracy and precision, from single piece glass pipettes to more complex adjustable or electronic pipettes. Many pipette types work by creating a partial vacuum above the liquid-holding chamber and selectively releasing this vacuum to draw up and dispense liquid ...

3. Air displacement pipette - Wikipedia

   en.wikipedia.org/wiki/Air_displacement_pipette

   Whereas manual pipettes need a movement of the thumb (up to 3 cm), electronic pipettes have a main button. The programming of the pipette is generally done by a control wheel and some further buttons. All settings are displayed on a small display. Electronic pipettes can decrease the risk of RSI-type injuries. [9] [10]

4. Reverse pipetting - Wikipedia

   en.wikipedia.org/wiki/Reverse_pipetting

   Reverse pipetting is a technique to dispense a measured quantity of liquid by means of air displacement pipette.The technique is mainly recommended for solutions with a high viscosity or a tendency to foam: [1] as it reduces the risk of splashing, foam or bubble formation.

6. Positive displacement pipette - Wikipedia

   en.wikipedia.org/wiki/Positive_displacement_pipette

   Positive displacement pipettes are a type of pipette that operates via piston-driven displacement. [1] [2] Unlike an air displacement pipette, which dispenses liquid using an air cushion in the pipette tip, the piston in a positive displacement pipette makes direct contact with the sample, allowing the aspiration force to remain constant.

7. Graduated pipette - Wikipedia

   en.wikipedia.org/wiki/Graduated_pipette

   A small pipette allows for more precise measurement of fluids; a larger pipette can be used to measure volumes when the accuracy of the measurement is less critical. Accordingly, pipettes vary in volume, with most measuring between 0 and 25.0 millilitres (0.00 and 0.88 imp fl oz; 0.00 and 0.85 US fl oz). [2]
