Final answer:
To transfer a blood sample from a syringe to a vacutainer tube, use a pre-sterilized glass or plastic graduated pipette and hold the tube at an angle to minimize contamination. Pass the opening of the tube through a flame before and after the transfer to further prevent contamination.
Step-by-step explanation:
To transfer a blood sample from a syringe to a vacutainer tube, you would use a pre-sterilized glass or plastic graduated pipette. These pipettes are used to transfer specific volumes of sterile liquids accurately. When transferring the blood sample, tubes or bottles should be held at an angle to minimize the potential for airborne contaminants. It is also recommended to pass the opening of the tube or bottle briefly through a flame before and after the transfer to discourage airborne contaminants from getting into the sterile liquid.
