What does the acronym TD stand for in the context of pipettes?

In the context of pipettes, the acronym TD stands for "Volume delivered by a specific pipette." This is an important designation in laboratory settings, particularly when precision in measurement is required for experiments and assays. The TD notation indicates that the pipette has been calibrated to deliver a specific volume of liquid accurately.

Understanding this is crucial for anyone working in a laboratory because it ensures that they are using the correct volume of liquids in their experiments, which can significantly affect the results. Knowing that a pipette is a TD type allows researchers to trust that the volume they set on the pipette corresponds to the volume that is actually delivered, which supports reproducibility and accuracy in scientific research.
