Microbiology is Fun!

What is Microbiology? Micro - too small to be seen with the nacked eye Bio - life logy - study of (The science that studies micro organisms)

Organisms included in the study of Microbiology Bacteria Algae Fungi Viruses Microorganisms - Microbes - Germs

Microbiology equipment

Petri dish A petri dish is a flat dish made of plastic or glass with a cover that is used to grow microorgansim

Incubator Incubator is a warm cabinet that you can set it's temperature to a proper temperature for microbs growth. a good temperature for most bacteria is About 35ºc and agood temprature for most fungi is 25°c.

Hot air oven This kind of dry heat sterilization is recomended when it is undesirable that steam make contact with the material to be sterilized. This is true for glasswares – glasspetriplates, Pipettes as well as for substances like oil, powder, etc.

Autoclaves autoclave sterilizes items by heating them with steam to a very high temperature (121 degrees° C/15 p.si). The advantage of using an autoclave is that it can reach temperatures higher than boiling water alone , so it can kill not only bacteria but also bacterial spores, which tend to be resistant

Bunsen burner Bunsen burner is produces gas flame which used for heating, sterilization (inoculating loop)

glassware beaker tube flask

pipette

The Microscope

With a binocular microscope, adjust oculars for both eyes!

Don’t shut one eye while observing under the microscope!

Microscope Care Always carry with 2 hands Only use lens paper for cleaning Do not force knobs Always store covered

How to properly carry the microscope

Microscope Parts Eyepiece Body Tube Revolving Nosepiece Arm Objective Lens Stage Stage Clips Coarse Focus Diaphragm Fine Focus Light Base

Using the Microscope Place the Slide on the Microscope Use Stage Clips Click Nosepiece to the lowest (shortest) setting Look into the Eyepiece Use the Coarse Focus

Follow steps to focus using low power Click the nosepiece to the longest objective Do NOT use the Coarse Focusing Knob Use the Fine Focus Knob to bring the slide
