Our Glass Petri Dish is a staple labware made of high-quality glass, featuring high temperature and chemical corrosion resistance. Designed for microbial and cell culture, it also suits sample inoculation, observation and short-term storage. With a smooth flat bottom and well-sealed lid, it ensures sterile culture environment and prevents contamination. Reusable after high-temperature sterilization, this glass petri dish is widely applied in microbiology, biochemistry, medical research and routine lab experiments, meeting standard lab operation requirements.
Our borosilicate glass petri dish is crafted from 3.3 borosilicate glass, the premium lab material that makes our high temperature glass petri dish withstand -20°C to 500°C temperature shifts. It resists cracking during autoclaving and chemical corrosion, with a 50% longer service life than soda-lime glass, ideal for repeated lab sterilization cycles and harsh experimental conditions.
The 90mm glass petri dish is our flagship product with CNC-machined precision, boasting a flatness tolerance of ≤0.02mm for uniform microbial and cell culture. This standard **petri dish** size fits all lab incubators and laminar flow hoods, with customizable rim designs for enhanced sealing. Each batch is calibrated for dimensional accuracy, ensuring consistent experimental results every time.
Every glass petri dish undergoes 121°C high-pressure steam sterilization, validated by third-party labs to achieve 99.99% sterility with zero endotoxin residues. Our petri dish comes with a traceable sterilization certificate per order, eliminating pre-use preparation time and reducing contamination risks for sensitive microbiology and cell culture experiments.
Our borosilicate glass petri dish is fully autoclavable and reusable, capable of withstanding over 50 high-temperature sterilization cycles without deforming or fading. Unlike disposable plastic alternatives, this high temperature glass petri dish cuts long-term lab procurement costs by 60% and is eco-friendly, aligning with sustainable lab operation standards worldwide.
It is the primary tool for cultivating bacteria, fungi, actinomycetes and other microorganisms. Placed in a sterile incubator, it provides a stable environment for microbial growth, allowing lab technicians to observe colony morphology, count colony units and conduct strain identification for microbiology research and clinical pathogen detection.
Widely used in food safety and environmental monitoring labs. It cultivates microbial samples from food, drinking water, soil and air, to detect the number of harmful bacteria and judge whether the samples meet safety standards.
Suitable for static culture of adherent animal and plant cells in basic biological research. Its smooth borosilicate glass surface is non-toxic to cells and easy for cell attachment, ideal for short-term cell culture and morphological observation in college labs and basic biochemistry research projects.
A must-have labware for biology, medicine and food science courses in universities and vocational colleges. It is used for teaching basic experimental operations such as microbial inoculation, streaking and culture, helping students master core lab skills and understand microbial growth characteristics through intuitive observation.
1. Perform all steps in a sterile lab environment (laminar flow hood) to avoid contamination.
2. Open the sterile dish gently, pour 15-20ml liquid culture medium into the bottom, and let it solidify at room temp.
3. Inoculate the medium surface with your sample via streaking/spreading, then cover the lid tightly.
4. Incubate the dish upside down at the required temperature (e.g., 37°C for microbial culture) for the specified time.
5. After use, sterilize the dish again before cleaning or disposal.
