What is aseptic technique?
Aseptic technique refers to procedures that prevent contamination during laboratory work.
Why is handwashing important in the lab?
Handwashing minimizes the risk of contamination and maintains a sterile environment.
How do you use a serological pipette?
A serological pipette should be used with a pipette aid, ensuring the tip remains sterile.
What are the types of pipettes?
There are serological pipettes and micropipettors, each designed for specific volume ranges.
What should you do with used pipettes?
Dispose of plastic pipettes in a sharps container and immerse glass pipettes in bleach solution.
How can I improve my pipetting technique?
Practice is key; ensure you are familiar with the instruments and maintain a steady hand.
