A michroscope has a 20x ocular and two objectives of 10x and 43x respectively: calculate the apparent magnification for low and high power lenses.
Label three sets of eight microfuge tubes (1-8) and add the volumes of BSA stock solution (2
mg/ml) and water to each labeled tube as indicated in Table 3. Be sure to calculate, and enter,

- Using the scanning (4x) objective and the metric ruler, record the number of millimeters you see along with the letter “e.” Your value: 2 millimeters Convert the figure you attained to micrometers (1 millimeter = 1,000 micrometers). This is the diameter of the field of view for the low-power objective (LPD). The field of view is the circular field you see when you look through the oculars. The field of view changes at different magnifications.
