Generally, a pipette has optimal accuracy from 35-100% of its nominal volume, and should not be used below 10% of that volume. [5] For example, using a 1,000 μl pipette for 50 μl of liquid is not ideal, and using a 100 μl pipette will give better results. [6] Other factors like tip angle and immersion depth may also impact accuracy ...
A pipette (sometimes spelled as pipet) is a type of laboratory tool commonly used in chemistry and biology to transport a measured volume of liquid, often as a media dispenser. 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 ...
A media dispenser or a culture media dispenser is a device for repeatedly delivering small fixed volumes (typically between 1 ml and 50 ml) of liquid such as a laboratory growth medium like molten agar or caustic or volatile solvents like toluene into a series of receptacles (Petri dishes, test tubes, Fernbach flasks, etc.).
A Mohr pipette, also known as a graduated pipette, is a type of pipette used to measure the volume of the liquid dispensed, although not as accurately as a volumetric pipette. [1] These use a series of marked lines (as on a graduated cylinder) to indicate the different volumes. [ 2 ]
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.
Typical volumes are 1, 2, 5, 10, 20, 25, 50 and 100 mL. Volumetric pipettes are commonly used in analytical chemistry to make laboratory solutions from a base stock as well as to prepare solutions for titration. ASTM standard E969 defines the standard tolerance for volumetric transfer pipettes. The tolerance depends on the size: a 0.5-mL ...
