Lab bench level aseptic technique emphasizes the preparation of a clean workspace, labeling, sterile transfer of liquids, and transfer of a microorganism from solid to liquid culture media.  Earners of this credential have aseptic technique knowledge and awareness of creating a clean lab bench.

Earners of this credential have shown mastery of the following tasks:​

  • Prepare the lab bench surface for aseptic benchwork.

  • Handle instruments such as Bunsen burner (or equivalent), striker, inoculating loop, test tubes, serological pipet, pipet pump, and agar plates appropriately

  • Aseptically transfer a bacterial colony to a culture tube with broth media.

  • Aseptically transfer a volume of sterile broth to a new sterile tube.



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

  • Transfer a bacterial colony 

  • Arrange all materials in efficient locations while transferring

  • Make sure a Bunsen burner is lit appropriately and adjust if necessary



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.
