Final answer:
To clean a knife edge (cuneo) strainer, one must rinse it with solvent and use a glass rod to swirl the solid in the solvent after opening the apparatus to the atmosphere and turning off the aspirator.
Explanation:
The action that must be taken during normal operation to clean a knife edge (cuneo) strainer is to rinse with solvent. This involves opening the apparatus to the atmosphere, followed by turning off the aspirator. Subsequently, you would add a few mL of cold solvent to the filter paper. With the use of a glass rod, the solid can be delicately swirled in the solvent, enhancing the cleaning process.
Overall, cleaning a strainer effectively in an experimental or industrial setting requires an understanding of safety protocols and proper technique to ensure that the strainer is adequately cleaned without causing damage or contamination to the device or the system it is a part of.
