100mm x 15mm Petri Dish for Laboratory Culture and Experimentation Use

The Versatile 100mm x 15mm Petri Dish An Essential Tool in Laboratories

When it comes to laboratory work, the importance of effective and efficient tools cannot be overstated. Among them, the Petri dish stands out as a quintessential item in microbiology and several other scientific fields. The 100mm x 15mm Petri dish, in particular, is a staple in laboratories around the world, known for its versatility and practicality.

What is a Petri Dish?

A Petri dish, also known as a Petri plate, is a shallow, cylindrical, flat dish made of glass or plastic. Typically featuring a lid, the dish provides an ideal environment for growing microorganisms or for various other experimental procedures. The 100mm x 15mm size is especially popular because it offers an optimal surface area for the cultivation of bacteria, fungi, and other cells while being manageable in terms of handling and storage.

The Petri dishes are usually made from high-quality glass or polystyrene, ensuring transparency that allows easy observation of the contents. Glass dishes can be sterilized in an autoclave, making them reusable, while plastic Petri dishes are often disposable, which can enhance convenience in high-throughput environments. The 100mm x 15mm dimension provides ample space for multiple samples, making it a preferred choice for educators, researchers, and clinicians alike.

Applications in Microbiology

In microbiology, the 100mm x 15mm Petri dish is predominantly used for culturing microorganisms. The wide surface area allows for the application of a variety of media, ranging from agar plates for growing bacteria to selective media that target specific types of microorganisms. This capability is critical for researchers aiming to isolate and identify different species of bacteria or fungi.

In addition to cultivating microbes, these dishes are also employed in antibiotic susceptibility testing. The disk diffusion method, commonly known as the Kirby-Bauer test, uses these dishes to assess the effectiveness of antibiotics against particular pathogens. By placing antibiotic-impregnated disks on an agar plate inoculated with bacteria, researchers can quantify the zone of inhibition and determine whether a microorganism is susceptible or resistant to a specific antibiotic.

Use in Cell Culture

Beyond microbiology, Petri dishes are vital in the field of cell culture. The 100mm x 15mm size provides ample space for growing eukaryotic cells, including plant and animal cells, under controlled conditions. In laboratory settings, these dishes can be coated with various substances to facilitate cell attachment and growth. They are essential tools for studying cellular processes, drug interactions, and genetic modifications, contributing significantly to advancements in biotechnology and medicine.

Educational Relevance

In educational settings, the 100mm x 15mm Petri dish serves as an introductory tool for students learning about microbiology, cell biology, and experimental techniques. Students conduct projects that involve growing bacteria from environmental samples, investigating the effects of different variables on microbial growth, and performing hands-on experiments that bring theoretical concepts to life. The use of these dishes enables educators to foster a better understanding of scientific methodologies while promoting critical thinking and inquiry-based learning.

Conclusion

The 100mm x 15mm Petri dish is more than just a simple laboratory tool; it represents a convergence of design, functionality, and educational value. Whether used in microbiological experiments, cell culture, or classroom demonstrations, this versatile dish proves to be a fundamental asset in various scientific endeavors. The ability to cultivate and observe microorganisms or cells in a controlled environment has been paramount in many significant scientific breakthroughs. As research continues to evolve, the humble Petri dish remains at the forefront, facilitating exploration and discovery in the life sciences. For anyone engaged in biological research or education, the 100mm x 15mm Petri dish is an indispensable element that underpins countless investigations and innovations.
