Main Petri Dish products
Standard Petri Dishes
The first choice for laboratories. the dishes has good properties of being high-transparent, sterile, and can withstand a temperatures range of 0°C 80°C.
Square Petri Dishes
Widely used in laboratory testing to facilitate microbial observation and improve experimental efficiency.
Divided Petri Dishes
It is sterile, transparent and space‑saving, which brings great convenience to the microbial culture and experimental process.
Petri Dish With Grid
Grid is specially used for bacterial colony counting and microbial detection. the clear grid can locate quickly and reduce counting errors
Application
Medical Field: they are mainly used for clinical specimen culture, bacterial and fungal detection, pathogen isolation and identification, drug sensitivity testing, and laboratory diagnostic analysis. They play an important role in hospital laboratories, clinical testing centers, and disease prevention institutions, helping to detect infections, assist disease diagnosis, and monitor medical hygiene environments safely and efficiently.
Chemical Industry: they are used for sample preparation, small‑scale reaction observation, crystal growth, catalyst testing, powder and particle storage, physical and chemical property analysis. They provide a clean and contamination‑free container for handling chemical samples, ensuring safe and accurate experimental operation.
Classroom Teaching: used for observing microorganism growth, conducting biology experiments, seed germination tests, plant cultivation, scientific demonstration and hands-on practical activities. They help students observe experimental results intuitively, understand scientific principles clearly, and make science teaching safer and more vivid.
Experiment equipment: Petri dishes are widely used as basic experimental containers for microbial cultivation, bacterial colony counting, cell culture, and sample observation. They are commonly matched with microscopes, constant temperature incubators, clean benches and other laboratory instruments to form a complete set of experimental systems, providing a stable and sterile environment for scientific research, medical testing and biological analysis.
Beauty Industry: used for cosmetic sample testing, skin care ingredient analysis, microbial contamination detection, beauty tool hygiene testing, and small-scale formula development experiments. They ensure safe, hygienic and accurate testing of beauty and personal care products.
scientific research: Petri dishes serve as essential tools for microbial culture, cell incubation, strain isolation, drug sensitivity testing, and biological sample observation. They are widely used in life science research, microbiology studies, pharmaceutical development, and environmental science experiments to support data collection, experimental analysis, and scientific exploration.
What is Disposable Plastic Petri Dish？
petri dish
Petri dish is also known as petri plate and cell culture dish.
The surface of this kind of dish is transparent and smooth, not easy to deform, and it is sterile, non-toxic and chemically stable.
Operating temperature range 0–80°C.
It is mainly used for microbial culture, bacterial counting and laboratory detection to provide a clean and contamination-free environment.
Its function is to ensure safe and accurate observation of strains and cell growth.
The uses and characteristics of Petri Dish
1. Material
There are many types of plastic culture dish materials. Generally speaking, materials with high transparency, good chemical stability and non-toxicity are suitable for making culture vessels. The most widely used and cost-effective material is medical-grade polystyrene (PS)
2. petri dish base material and requirements
The base materials that can be used to produce petri dish are mainly two types of polymer materials, namely polystyrene (PS), polypropylene(PP)
Quality requirements include:
① high transparency, which allows clear and unobstructed observation.
② good toughness to avoid problems such as petri dish crack or break during operation, transportation and storage.
③ uniform thickness.
④ high smoothness to reduces adhesion of colonies and cells.
⑤ light weight and stackable, reducing the labor intensity and saving space in laboratories.
⑥ good chemical stable, avoiding the dish from reacting with culture media, reagents or experimental samples.
FAQ
Q: What material is plastic petri dish generally made of?
A: petri dish is usually made of PS plastic or PP plastic.
Q: Is petri dish safe to use? Will it have any adverse effects on experimental accuracy?
A: Sunny’s petri dish is made of medical-grade materials, non-toxic and odorless, ensuring product quality.
Q: Can petri dish be reused?
A: It is generally not recommended to reuse petri dish. After using once, the petri dish may ramin with residual bacturia, culture media, chemical reagents etc., which will affect the experimental results and cross-contamination of the next use.
Q: Can plastic petri dish be used in the autoclave?
A: No, High temperature and pressure will cause deformation, melting and material damage, which will affect the experiment and lead to contamination.
Q: What is petri dish used for?
A: petri dish-also known as culture dish or cell culture dish, as it is often called petri plate in the laboratories-is a transparent plastic container that is used for microbial culture and cell experiments.
Q: What is the difference between glass petri dish and plastic petri dish?
A: glass petri dish is made of heat-resistant glass, which can be autoclaved repeatedly, making them ideal for long-term use, plastic petri dish is sterilized and disposable, so if you are difficult to clean, choose the plastic petri dish to prevents cross-contamination and ensures convenient and safe use.
