Petri Dish Glass 100mm
A 100mm glass Petri dish is a foundational laboratory tool, typically manufactured from durable, heat-resistant borosilicate glass (3.3) or soda-lime glass. Due to its ability to be sterilised and reused, it is primarily used in microbiology and research to grow and observe microorganisms.
Here are the primary uses for 100mm glass Petri dishes:
1. Microbiological Culture (Bacteria/Fungi)
Agar Plates: The most common use is to pour nutrient agar into the dish to create a solid culture medium for growing bacteria, fungi, and yeasts.
Isolation and Identification: Researchers use these to isolate specific microbial colonies from a mixed sample, identifying them by growth patterns and color.
Sensitivity Testing: Used in antimicrobial susceptibility testing (disc diffusion method) to determine how well antibiotics kill bacteria.
2. Cell Culture and Biology
Cell Cultivation: Used for growing mammalian or plant cells in research settings.
Seed Germination: Frequently used to study the early stages of plant development and seed germination.
Tissue Culture: Ideal for cultivating small mosses, algae, or tissue samples.
3. Laboratory and Analytical Applications
Sample Observation: The 100mm size is ideal for viewing colonies with the naked eye or a low-power microscope.
Evaporation and Drying: Due to the wide surface area, they are used to evaporate liquids or dry out samples/precipitates in chemical labs.
Sample Storage: Used as a temporary, covered container to hold, store, or transport samples, such as insects, tissue samples, or seeds.
Microscopy: Because they are made of clear, flat glass, they can be placed directly under a microscope.
4. Other Uses
Educational Demonstrations: Extensively used in school and college labs for biology experiments.
Art and Hobby: Used by artists or hobbyists to store small items like beads, sequins, pins, or buttons.
Advantages of 100mm Glass Over Plastic
Autoclavable: Glass Petri dishes can be sterilized in an autoclave (wet) or oven (dry) for repeated use.
Durability: High resistance to heat and harsh chemicals.
Clarity: Excellent optical quality for detailed viewing.
Note: 100mm glass Petri dishes are generally paired with a loose-fitting lid, which allows for some gas exchange, making them suitable for aerobic cultures, though this should be sealed with paraffin film for long-term storage.
