Final answer:
When removing a differential flow instrument with a liquid seal from service, it is important to hold the tubes or bottles at an angle to minimize airborne contaminants and pass the opening through a flame for sterility. Additionally, if the instrument has a liquid seal, follow the manufacturer's instructions for proper removal.
Step-by-step explanation:
When removing a differential flow instrument with a liquid seal from service, there are a few steps to follow:
- Make sure to hold the tubes or bottles at an angle during the transfer process. This helps minimize the potential for airborne contaminants to enter the opening.
- Pass the opening of the tube or bottle briefly through a flame both before and after the transfer process. This discourages airborne contaminants from getting into the sterile liquid.
- If the instrument has a liquid seal, it is important to follow the specific manufacturer's instructions for removal, as it may involve additional steps such as sealing the liquid and weighing the flask to determine the sample's mass.
