  • test tube holder

    are very common in the laboratory setting.
  • test tube holder
    These are finger-like lengths of glass or clear plastic tubing which is open in one end and rounded with a U-shaped bottom.
  • microscope glass slides
    A thin flat piece of glass used to hold objects for examination under the microscope.
  • microscope slides
    The specimen for observation is usually placed or "mounted "on the slide and then both are inserted together in the microscope for magnification.
  • inoculation loop
    A simple tool that is used to retrieve an inoculum from a culture of microorganism.
  • inoculation loop
    It is also known as a smear loop, an inoculating wand or microstreaker.
  • inoculation loop
    It is used in the cultivation of microbes on Petri dishes by transferring the inoculum for stealing.
  • inoculation loop
    is first sterilized in a flame until it turns to red-hot before and after each use in order to prevent cross-contamination. Right after flame the killing of the next cells upon which the inoculation loop touches.
  • pipette
    An instrument that is used to transport a measured volume of liquid.
  • pipette
    they come in different designs because of the different purposes they serve requiring different level of accuracy and precision.
  • TYPES OF PIPETTE
    1. Fillers
    2. Helpers
    3. Light-guided pipetting systems
    4. Pipette tips
  • bunsen burner
    Named after Robert Bunsen
  • bunsen burner
    is a laboratory equipment that produces a single open gas flame for heating, sterilization and combustion.
  • petri dish
    Named after Julius R. Petri
  • petri dish
    is a shallow cylindrical covered container or dish that is often made of glass or plastic.
  • petri dish
    It is used to culture cells or small moss plants.
  • medical autoclave
    The simplest forms of autoclave.
  • medical autoclave
    It is steam to sterilize equipment and other objects in order to inactivate microorganisms.
  • BASIC MICROBIOLOGY MEDIA
    It is essential that scientists are able to grow or culture them under controlled conditions. Culture medium is a liquid or gel designed to support the growth of microorganisms or cells or small plates.
  • Two Fundamental types of culture media
    cell culture and microbiological culture
  • Nutrient broths
    contains amino acids and nitrogen although its source may contain other compounds with unknown composition.
  • Types of culture media
    1. nutrient broth and Agar plates
  • Nutrient broths
    These contain all the elements that most bacteria need to grow.
  • Nutrient broths
    These are non-selective so it is used for general cultivation and maintenance of bacteria kept in laboratory culture collections
  • Agar plates
    a petri plate that contains a growth medium in order to culture or grow microorganisms or even small plants such as moss. In some instances, selective growth compounds can be added to the media such as antibiotics.
  • GENERAL TYPES OF MEDIA ACCORDING TO PURPOSE
    1. Minimal media
    2. Selective media
    3. Differential media
    4. Transport media
    5. Enriched media
  • Minimal media
    contain minimum nutrients possible for colony growth usually in the absence of amino acids
  • Selective media
    used for the culture of only select microorganisms.
  • Differential media
    also known as indicator media, used to differentiate one microorganism from another grown on the same media using the biochemical characteristics of microorganisms.
  • Transport media
    used as a temporary storage of specimens being transported to the laboratory for cultivation contains only buffers and salt
  • Enriched media
    contain nutrients required to support the growth of a variety of microorganisms, including fastidious species.
  • TYPE OF BLOOD AGAR PLATE
    1. Blood agar plate
    2. Chocolate agar
    3. Thayer-Martin agar
    4. Thiosulfate citrate bile salts sucrose-enriched agar
  • Blood agar plate
    contains mammalian blood used to isolate fastidious organisms and detect hemolytic activity such as Streptococcal species.
  • Chocolate agar
    a type of blood agar plate where the blood cells have been blessed by heating the cells to 56oC and is used to culture fastidious respiratory bacteria such as Haemophilus influenzae.
  • Thayer-Martin agar
    chocolate agar used to isolate Neisseria gonorrhoeae
  • Thiosulfate citrate bile salts sucrose-enriched agar
    a type of blood agar plate that enhances the growth of Vibrio Species including V. cholerae
