Types Of Pipettes

Does not have graduations to the tip.it is a self-draining pipette, but the tip should not be allowed to touch while the pipette is draining.

has graduation marks to the tip and is generally a blowout pipette

is a pipette with a total holding volume of less than 1 mL; it may be designed as either a Mohr or a serologic pipette.

are used with biologic fluids having a viscosity greater than that of water. They are blowout pipettes, indicated by two etched continuous rings at the top.

is designed to dispense or transfer aqueous solutions and is always self-draining

The bulb- like enlargement in the pipette stem easily identifies the

This type of pipette usually has the greatest degree of accuracy and precision and should be used when diluting standards, calibrators, or quality control material. They should only be used once prior to cleaning.

are designed to dispense one volume without further subdivisions.

Pipette with a pipetting capability of less than 1 mL

pipette that dispenses greater than 1 mL

may or may not have calibration marks and are used to transfer solutions or biologic fluids without consideration of a specific volume.

These pipettes should not be used in any quantitative analytic techniques.

are able to attach multiple pipette tips to a single handle and can then be used to dispense a fixed volume of fluid to multiple wells, such as in delivery to a multiwell microtiter plate.
