Accurate transfer of small volumes is an essential skill in the laboratory.  This hands-on assessment evaluates mastery of liquid transfer from 1 microliter to 25 milliliters.  Earners of this credential are able to accurately select the appropriate transfer instrument (micropipette or serological pipette), consistently transfer the appropriate volume, and demonstrate volume awareness in selecting container size.

Throughout the testing process, the credential earner should wear appropriate Personal Protective Equipment (PPE) and work safely.  Volumes of liquid to be measured accurately will range from 1 microliter to 50 milliliters.

Required tasks to earn this credential

Credential earners will be asked to complete the following tasks while being observed by BCSI evaluators:

  1. Determine the appropriate device to use to deliver three different volumes (A, B, C) of liquid into new containers.  Multiple aliquots of each volume will be delivered into new tubes. (For example 4 aliquots of Volume A, 4 aliquots of Volume B, etc.)



When you are ready to schedule your credential assessment, ensure that you can complete the tasks listed below: 

  • Choose the correct instrument based in the volume of liquid

  • Ensure correct tip is chosen when necessary

  • Interact with given pipette instruments and equipment appropriately

  • Dispose of tip or pipette correctly



For your $20 credential fee, you will be assessed in-person on the tasks listed above and issued a digital credential through Badgr.  Our evaluators are available on a flexible schedule.
