What is TD and TC pipette?
TC or TD abbreviated for “to contain” and “to deliver” respectively. In a 'TC' marked pipette, the contained quantity of the liquid corresponds to the capacity printed on the pipette, While in 'TD' marked pipette, the delivered quantity of liquid corresponds to the capacity printed on the pipette.Feb 13, 2019
What are the types of pipettes and when are they used?
The five grades of pipettes include disposable/transfer, graduated/serological, single-channel, multichannel, and repeat pipette. From the most basic transfer pipette dropper to the advanced repeat dispensing pipettor, the manner in which the equipment is handled will impact the accuracy of the test results.
What are the types of pipettes used in the chemistry laboratory?

What does TD mean on a pipette?
TD = to deliver; the pipette is calibrated to deliver a defined amount of. liquid; residual liquid is included; only aqueous solutions.
What is the difference between TD and TC glassware?
Glassware designed to contain, like graduated cylindersgraduated cylindersThe volume of these objects can be found by water displacement. A volume of water sufficient to cover the object is placed in a graduated cylinder and the volume read. The object is added to the cylinder and the volume read again. The difference between the two volumes is the volume of the object.http://dept.harpercollege.edu › chm › thedisk › labtech › solvolMeasuring Volume of Solids - Harper College and volumetric flasks, are usually marked with a TC. ... Glassware designed to deliver, like pipets and burets, are marked with a TD. These pieces of glassware account for the small amount of liquid that remains behind.
Is volumetric pipette TD or TC?
Calibrated pipets, burets, syringes and droppers are T.D. glassware; volumetric flasks and cylindrical or conical graduates are T.C. glassware although in practice, graduates are used as T.D. vessels for volumes of 1 ml or more.
How do you use TD pipette?
- Fill the pipette with a pipetting aid to approx. 5 mm above the selected graduation mark.
- Remove any liquid remaining on the outside of the tip of the pipette with a tissue.
- Set the meniscus.
- Wipe off any drop of liquid adhering to the tip.
What is the difference between the function of graduated and volumetric pipette?

What is the difference between pipettes?
Pipette and pipet describe completely different liquid handling devices—for example, pipette is used for the device that you use pipette tips with, whereas a pipet describes the glass (or plastic) tubes used for serology (serological pipet) and chemistry (volumetric pipet).
