The marking TD on a pipet - ANSWER A to deliver pipet is marked with the letters TD near the top of the
pipet. This means that the pipet is calibrated to deliver the volume marked on the pipet in a specified
time and at a specified temperature when the pipet is emptied by gravity drainage. When used correctly,
the TD pipet delivers the specified volume of fluid, leaving a small drop of fluid in the pipet tip. A TD
pipet with a frosted band etched around the top of the pipet is called a blowout pipet.
What is the difference in serological and volumetric? - ANSWER Serological- have a total capacity
marking near the suction end and are usually labeled TD. Are graduated to the tip, with markings
indicating uniform increments. These pipets can be used to transfer total capacity or partial volume.
These pipets usually marked TD and have frosted band. Volumetric- have a wide opening on the
suctioning end, an oval bulb in the center, and a tapered tip on the dispensing end. Are usually labeled
TD and are used when critical measurements are required, such as when preparing standards. Each
volumetric pipet is marked and calibrated to deliver only one volume. Volumetric pipets are used by
attaching a suctioning aid or pipet filer to the top of the pipet.
