![]() ![]() ![]() ![]() Measurement accuracy varies greatly depending on the instrument. 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. 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. Various pipettes and related items: 1) Adjustable pipettes, from left: 20–200 μl, 2–20 μl, 100–1000 μl 2) Graded transfer pipette and electric pipette filler 3) 25 mL, 10 mL, 5 mL, and 2 mL transfer pipettes 4) Disposable tips for adjustable pipettes 5) 12-channel adjustable pipette for microplates 6) Low-retention 0.5–10 μl adjustable pipette 7) Squeezable transfer pipettes 8) Digital adjustable pipette 9) Light-guided pipetting systemĪ pipette (sometimes spelled as pipet) is a laboratory tool commonly used in chemistry, biology and medicine to transport a measured volume of liquid, often as a media dispenser. ![]()
