Once oil is used on a slide you should never return to

• the oil immersion lens

• Scanning power lens

• Medium power lens

• High dry 40X lens

How should the microscope objectives be positioned when placing the small drop of oil over the specimen?

• in between the 40x high dry objective and 100x oil immersion objective.

• in between the 100x oil immersion and the scanning objective.

• the oil immersion objective should be rotated and clicked into place.

• it does not matter as long as you can get the oil under the objective.

When a student finishes using the oil immersion technique they should do which of the following to clean up the microscope.

• Unplug the microscope and put the dust cover on.

• clean the immersion oil off he high dry 40x lens

• clean the immersion oil off the 100x lens, unplug the microscope and put the dust cover on.

• don't worry about it the teacher will get it
