MICR 290 Lab (Microbiology Laboratory)
Week 1 Lab Report (Lab Safety and Use
of The Microscope)
70% - ANS-Common dilution of ethanol or isopropyl alcohol in laboratory use.
70% Alcohol - ANS-Most generally used disinfectant in a laboratory.
Budding Cells Yeast - ANS-What kind of microorganism is a Saccharomyces cerevisiae?
Common PPE - ANS-Include:
o Lab Coat
o Gloves
o Safety Goggles
o Face Mask
o Chemical Apron
Compound Binocular Light Microscope - ANS-Common laboratory microscope.
Ethanol or Isopropyl Alcohol - ANS-Type(s) of alcohol used to smooth the surfaces in a
laboratory.
High Power - ANS-40X x 10X = 400X
Initial Measurement x Total Lens Magnification - ANS-Formula to discover the dimension of a
specimen underneath the microscope.
Ex: A bacterium that is 2 micrometers long is what number of millimeters below the 40X goal
lens?
2 µm x 400 = 800 µm → 0.8mm
Laboratory Safety Habits - ANS-o Do no longer contact face or mouth.
O Disinfect the workspace.
O Wash palms regularly even after sporting gloves.
Low Power - ANS-10X x 10X = 100X
Objective Lens x Ocular Lens - ANS-Total magnification method.
