====Variations====
None



====Safety Precautions====
  *Never pipette by mouth - always use a pipette bulb.  
  *Avoid drawing liquid into the bulb to prevent contamination.  
  *Handle glass pipettes carefully to prevent breakage and injury.  
  *Dispose of pipettes properly if they become contaminated with hazardous solutions. 




====Questions to Consider====
  *Why is it important not to blow out a TD pipette? (They are calibrated to deliver the correct volume without forcing out the last drop.)  
  *What is the difference between a TD and a TC pipette? (TD delivers a specified volume, while TC is calibrated to contain a volume that must be completely expelled.)  
  *Why should a pipette be conditioned with the reagent before use? (It prevents dilution or contamination from residual liquid inside the pipette.)  
  *How can incorrect pipetting technique affect experimental results? (It can lead to inaccurate measurements and errors in solution concentration.)
