Some pipets are calibrated TC. Why would one ever want a pipet calibrated TC rather than TD ... 

Pipets calibrated TC are used for viscous solutions that do not drain well. For these, a pipet contains the solution and then the contained volume is rinsed out into the receiving vessel.

Save the spreadsheet you have just created by clicking on File SaveAs. I like to save documents to the desktop first. Then they can be dragged to whatever file you wish, for example. My Documents. That way they don t get lost. So select Desktop at the top. Give the document a File Name at the bottom, for example, Pipet Calibration. Then click Save. If you wish to place the saved document on a disk, you can drag it from the desktop to the opened disk.

Control of Pipet Calibration Using Graduated Tips... 

Accuracy and precision can easily be calculated by the formulae in Subheadings 3.2.2.I. and 3.2.2.2. In contrast to commercial pipet calibration computer software, the conversion factor for calculating the density of water suspended in air at the test temperature and pressure are not considered. For calibration of multichannel pipets, examine each channel separately. 

Reagents and Equipment. Place and dry in an oven at about 125 °C for 30 min, an air condenser and a 9-in. Pasteur pipet calibrated to deliver 0.9 mL. After removal from the oven, place these items in a desiccator and allow them to cool to room temperature. 

The use of graduated (Mohr type) pipets or of pipets calibrated for blow out is not recommended. Neither is the use of small pipets (2 ml, or less) unless it is first demonstrated that their accuracy and reproducibility are adequate.
