Final answer:
To aliquot a blood sample, open the blood tube at an angle to prevent contamination. Pass the tube opening through a flame to discourage airborne contaminants. Practice proper pipetting techniques to ensure accurate and efficient transfer of the sample.
Step-by-step explanation:
When aliquoting a blood sample, it is important to open the blood tube in a way that minimizes the potential for contamination. One method is to hold the tube at an angle during the transfer process to reduce the risk of airborne contaminants entering the tube. Additionally, passing the opening of the tube through a flame before and after the transfer can help discourage airborne contaminants.
It is also important to practice proper pipetting techniques when transferring liquids. Familiarize yourself with the markings on the pipette and practice drawing up and releasing water. This will help develop the skills needed to aliquot a sterile liquid accurately and efficiently.
