Petri Dish
Product Code : SCL-CLE-11920
The StemAids Petri Dish is a foundational laboratory vessel engineered for the cultivation, isolation, and visual analysis of microorganisms and cells. Featuring a shallow, cylindrical design with a loosely fitting lid, it provides a stable environment for the growth of cultures on solid media (typically agar). Manufactured to ISO 13132 standards, these dishes are essential for Microbiology, Mycology, and Cell Biology laboratories, offering high optical clarity for unobstructed observation.

Key Pedagogical & Laboratory Outcomes
- Cultivation Interface: Facilitates the understanding of Microbial Growth. Learners identify the morphology of bacterial or fungal colonies (color, margin, elevation) as they proliferate on the agar surface.
- Isolation Application: Enables the "Streak Plate" technique; learners apply an inoculum to isolate pure colonies from a mixed population for further diagnostic testing.
- Antibiotic Analysis: Supports the analysis of "Inhibition Zones"; students evaluate the efficacy of antimicrobial agents by measuring the clear area around antibiotic discs (Kirby-Bauer method).
- Observation Evaluation: Provides a platform for evaluating seed germination or small insect behavior, where the transparent lid allows for monitoring without disturbing the internal environment.
International Logistics & Compliance
StemAids ensures comprehensive OEM readiness for global institutional procurement:
- Packaging: Export-grade, high-protection packaging. Glass dishes are interleaved with protective tissue and nested in shock-absorbent cartons; plastic variants are vacuum-sealed in sterile sleeves.
- Documentation: Includes Manufacturer’s Authorization Form (MAF), Certificate of Conformance (CoC), and Sterility Certificates for disposable models.
- Durability: Borosilicate 3.3 glass models are specifically annealed to withstand repeated high-pressure steam sterilization (121?C at 15 psi) without clouding or cracking.
Direct OEM Sourcing Advantages
Procuring StemAids Petri Dishes directly ensures vertical manufacturing control:
- Planar Accuracy: Direct oversight of the forming process ensures the base is perfectly flat, allowing for a uniform thickness of agar, which is critical for consistent nutrient distribution and zone-of-inhibition measurements.
- Distortion-Free Optics: We ensure that both the lid and base are free from "waves" or striations, facilitating high-resolution photography and microscopic inspection through the glass.
- Direct Factory Inventory: Guaranteed availability of specialized "Sectioned" dishes (e.g., Bi-plates or Tri-plates) for side-by-side comparison of different media.
- Quality Assurance: Every batch is inspected for rim uniformity to ensure the lid fits securely yet allows for the necessary level of gas exchange required for aerobic cultures.
