Petri Dish Glass 100mm<\/p>\n
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. <\/p>\n
Here are the primary uses for 100mm glass Petri dishes:<\/p>\n
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. <\/p>\n
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. <\/p>\n
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. <\/p>\n
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. <\/p>\n
