High-Quality 100x15mm Petri Dishes for Laboratory Research and Experiments

The Importance and Versatility of 100x15mm Petri Dishes in Laboratory Research

Petri dishes, also known as Petri plates or cell-culture dishes, are fundamental tools in microbiology, cell biology, and various other scientific disciplines. Among the many sizes and types available, the 100x15mm Petri dish stands out for its versatility and effectiveness in various laboratory applications. This article will delve into its significance, typical uses, and the benefits it offers to researchers.

What Are Petri Dishes?

Petri dishes are shallow, cylindrical, flat-bottomed vessels made from glass or clear plastic, designed to hold a range of substances, including cultures of microorganisms, cells, or tissues. Named after the German bacteriologist Julius Richard Petri, who invented them in the late 19th century, they have become indispensable in laboratory practices.

The 100x15mm size is a standard dimension widely used in laboratories. This size provides ample surface area for culturing various organisms while maintaining a manageable volume. The depth of 15mm allows for sufficient growth medium without compromising the ability to observe and manipulate the cultures effectively.

Typically, Petri dishes are supplied sterile, which is crucial for preventing contamination in experiments. Most are made from polystyrene or polycarbonate plastic, which offers excellent clarity for observation and is chemically resistant, making them suitable for various experimental conditions. Additionally, some Petri dishes come with vented lids, aiding in gas exchange for cultures sensitive to atmospheric conditions.

Common Applications

1. Microbial Cultivation One of the primary uses of 100x15mm Petri dishes is to culture microorganisms, including bacteria, fungi, and yeasts. The large surface area allows researchers to spread samples evenly and observe colony morphology over time, aiding in identification and characterization.

2. Cell Culture Beyond microbial studies, these dishes are also employed for mammalian cell culture. The flat surface provides an ideal platform for the growth of adherent cells, enabling researchers to study cellular behavior under various experimental conditions.

3. Antibiotic Sensitivity Testing The 100x15mm format is popular for conducting antibiotic susceptibility tests using the Kirby-Bauer method. Researchers can spread a bacterial lawn on the agar surface and place antibiotic disks to assess the effectiveness of different antibiotics based on the zones of inhibition formed.

4. Plate Counts In food microbiology, these dishes are essential for performing total viable counts. By plating a diluted sample of food onto the agar surface, scientists can estimate the number of viable organisms present, which is crucial for food safety assessments.

5. Biotechnology Research In biotechnology, Petri dishes play a pivotal role in experiments related to genetic engineering, genetic screening, and plant tissue culture, where controlled conditions are essential for successful outcomes.

Benefits of Using 100x15mm Petri Dishes

The 100x15mm Petri dish is preferred for several reasons

- Ease of Handling Their design allows for easy stacking and maneuverability, making them practical for use in busy laboratory settings. - Clear Observation The transparent nature of plastic allows for excellent visibility, enabling researchers to monitor growth and detect contamination quickly. - Cost-Effectiveness Generally, Petri dishes are affordable and available in bulk, making them an economical choice for laboratories conducting numerous experiments. - Standardization The widespread use of this size facilitates standard protocols across different laboratories, ensuring consistency in experimental procedures and results.

Conclusion

The 100x15mm Petri dish is a critical tool in laboratory research, valued for its versatility, ease of use, and effectiveness in a wide range of applications. From microbial cultivation to antibiotic testing and cell culture, it plays an irreplaceable role in advancing scientific knowledge. As research continues to evolve, the importance of such fundamental tools remains unwavering, underscoring their essential place in the scientific community.
