This glass petri dish is manufactured from Type 3.3 borosilicate glass, conforming to ASTM E438 Class A standards for laboratory glassware. It is designed for microbial cultivation, cell culture, sample inoculation, and short-term specimen storage in laboratory and industrial applications. The flat bottom and matching lid support consistent culture conditions and reduce contamination risk during incubation. Units withstand repeated autoclave cycles, supporting cost efficiency for high-volume commercial procurement and sustainable laboratory operations.
Type 3.3 borosilicate glass exhibits a low coefficient of thermal expansion (3.3 × 10⁻⁶/K), enabling the dish to tolerate temperature shifts from -20°C to 500°C without structural failure. This property supports direct transfer from refrigerated storage to autoclave environments. The material also demonstrates resistance to common laboratory chemicals including weak acids, alkalis, and organic solvents used in microbiology workflows.
Standard 90mm diameter dishes feature a flatness tolerance of ≤0.02mm across the growth surface, measured via CNC machining inspection. This uniformity supports consistent colony distribution and microscopic observation. The rim design forms a stable seal with the lid, reducing airflow and moisture loss during extended incubation periods. Custom rim configurations are available for bulk orders with specified volume requirements.

Dishes withstand steam sterilization at 121°C and 0.1MPa per ISO 11134 standards. Ethylene oxide (EO) sterilization is available as a pre-treatment option for orders requiring ready-to-use units. Multi-compartment models (2-room, 3-room, 4-room) maintain structural integrity through equivalent sterilization cycles.
The dishes support cultivation of bacteria, fungi, and actinomycetes for colony morphology observation, colony-forming unit counting, and strain identification. These applications are standard in clinical pathogen detection laboratories and industrial quality control facilities.
Food safety and environmental testing laboratories use these dishes for microbial enumeration from food matrices, drinking water, soil, and air samples. Results support compliance verification against regulatory safety thresholds for commercial production and public health monitoring.
For basic biological research, the glass surface supports static culture of adherent plant and animal cells. The material is non-cytotoxic under standard culture conditions, suitable for short-term cultivation and morphological observation in academic and industrial R&D settings.
Educational institutions incorporate these dishes into biology, medicine, and food science curricula for instruction in inoculation, streaking, and culture observation techniques. Reusability supports repeated use in teaching environments with controlled sterilization protocols.
Perform all handling within a laminar flow hood or equivalent sterile environment. Pour 15-20ml of molten culture medium into the base and allow solidification at ambient temperature before inoculation.
Inoculate the medium surface via streaking or spread plate technique, then secure the lid. Incubate in inverted position at the temperature specified for the target organism (commonly 37°C for mesophilic bacteria).
After experimentation, collect all biological material and sterilize the dish via autoclave before cleaning. Visual inspection for scratches or etching is recommended between cycles, as surface damage may affect sterilization efficacy and cell attachment.
