FMB - Lab Lecture 1 Flashcards
Used for handling, isolating, transferring, and cultivating microbes.
Inoculating Loop
Used for stabbing bacteria vertically into deep tube of media to determine the shape of the hole digested by the bacteria.
Inoculating Needle
Used for spreading the bacteria in the plate.
L-shape glass rod
Can be used as spreader and can also be used during sampling instead of inoculating loops.
Cotton Swab
Allow the users to extract or deliver small amount of liquid of microbial dilutions.
- micro liter
- “exact quantity”
Mechanical pipettes
Used in heating substances and in incineration the specialized tool to avoid contaminants.
Alcohol Lamp
Used for the cultivation of microorganism on solid media.
Petri plates
Can be used for culturing, maintaining and storing cultures, specifically in broth.
Test Tubes
Important in microbial dilutions for microbial count.
Test Tubes
Hold the microbial cultures and store liquids.
Erlenmeyer Flask
Can also be used for the preparation of culture media.
Erlenmeyer Flask
Hold and work in mixing culture media and other liquids.
Beaker
Not recommended in culturing bacteria due to its open space or wide mouth.
Beaker
Latin word of Microscope
Microscopium
“to look at”
skopein
A laboratory instrument used to examine objects that are to small to be seen by the naked eye.
Microscope

- Ocular Lens
Maximum magnifying power of about ________.
1,000 x
Specimen remain in focus.
Parfocal
Remagnifies the image formed by the objective lens.
Ocular lens
Transmit the image from the objective lens to the ocular lens.
Body tube
Primary lenses that magnify the specimen.
Objective lenses
Holds the microscope slide in position.
Stage
Focuses light through the specimen.
Condenser
Controls the amount of light entering the condenser.
Diaphragm
Light source.
Illuminator
