Petri Dish Plastic 4”
Product Code : SCL-BLE-11864
The StemAids 4-Inch (100mm) Plastic Petri Dish is a high-transparency laboratory vessel engineered for the cultivation of microorganisms, cell culture, and seed germination. Manufactured from medical-grade, virgin polystyrene, these dishes provide an optimal growth surface and superior optical clarity for microscopic observation. Unlike glass alternatives, these lightweight plastic dishes are break-resistant and designed for high-volume institutional use in Biology, Mycology, and Pharmacology laboratories.

Key Pedagogical Outcomes (Bloom’s Taxonomy Alignment)
- Microbiological Interface: Facilitates student understanding of aseptic techniques and the isolation of pure cultures from environmental samples.
- Cultivation Quantification: Enables the physical study of microbial growth rates; learners apply nutrient agar and calculate Colony Forming Units (CFUs) over a 48-hour period.
- Antimicrobial Analysis: Supports the analysis of the "Zone of Inhibition"; students evaluate the effectiveness of various antibiotics or disinfectants using the Kirby-Bauer disk diffusion method.
- Morphological Evaluation: Allows students to evaluate and identify colony characteristics such as margin, elevation, and pigmentation directly through the transparent lid.
International Logistics & Compliance
StemAids ensures comprehensive OEM readiness for global institutional procurement:
- Packaging: Export-grade bulk packaging. Dishes are vacuum-sealed in heavy-duty polyethylene sleeves (typically 10 or 20 units per sleeve) to maintain sterility until the moment of use.
- Documentation: Includes Manufacturer’s Authorization Form (MAF), Certificate of Sterility (CoS), and Material Safety Data Sheets (MSDS).
- Durability: Engineered to withstand refrigeration (4?C) and incubator temperatures (up to 60?C) without warping or losing optical clarity.
Direct OEM Sourcing Advantages
Procuring the StemAids 4” Plastic Petri Dish directly ensures vertical manufacturing control:
- Venting Precision: Our lids are designed with precision-molded "lugs" that provide consistent ventilation, preventing the "vacuum seal" effect that can inhibit anaerobic or aerobic respiration.
- Flatness Guarantee: Direct oversight of the injection molding process ensures a perfectly flat base, which is critical for even agar distribution and consistent focal depth during microscopy.
- Direct Factory Inventory: Guaranteed availability of high-volume bulk orders (cases of 500 or 1000 units) to meet the demands of large university cohorts.
- Material Purity: We ensure the polystyrene is free from cytotoxic additives or heavy metals, preventing interference with sensitive biological assays.
