Overview
EN ISO 13132:2023 / ISO 13132:2023 specifies requirements and test methods for glass Petri dishes intended for general laboratory use and microbiological work. Adopted by CEN as EN ISO 13132:2023, this second edition updates the 2011 version and aligns dimensional, material and performance requirements for Petri dishes used in routine culture work, quality control and laboratory supply.
Key Topics
- Scope and purpose: Requirements and tests for glass Petri dishes for laboratory and microbiological applications.
- Types: Two types are defined - Type 1 (thick‑walled) and Type 2 (thin‑walled).
- Nominal sizes: Standard nominal diameters include 40, 50, 60, 80, 90, 100, 120, 150, 180 and 200 mm.
- Series and material classes:
- Series A and Series B: for hydrolytic resistance HGB 1 or HGB 2 glass (per ISO 719).
- Series C: new in 2023, for HGB 3 glass.
- Dimensions and tolerances: Precise dimensional tables (Series A, B, C) specify internal/external diameters, heights and wall thicknesses for bottom and top dishes.
- Designation format: Standardized naming (e.g., Petri dish ISO 13132 - 120 × 20 - 1A) to unambiguously identify size, type and series.
- Construction and performance:
- Requirements for base, side, edge and bottom flatness.
- Thermal shock resistance test methods added in this edition (referencing ISO 718).
- Glass quality: transparent, low residual strain, free from defects and pronounced tint.
- Marking and identification: Mandatory marking practices for traceability.
- Normative references: ISO 718 (thermal shock tests) and ISO 719 (hydrolytic resistance classification).
Applications
EN ISO 13132:2023 is used by:
- Manufacturers of laboratory glassware to design, produce and certify compliant Petri dishes.
- Laboratory procurement and quality managers who specify equipment for microbiology, culture work and routine testing.
- Testing and inspection laboratories that perform dimensional, hydrolytic and thermal-shock tests.
- Regulatory bodies and accreditation entities comparing products against recognized international requirements.
Practical uses include standardizing product ranges, ensuring compatibility of lids and bases (Series B pairing tolerances), and selecting appropriate hydrolytic class for specific microbiological assays.
Related Standards

- ISO 719 - Glass: hydrolytic resistance of glass grains at 98 °C - method and classification.
- CEN adoption: EN ISO 13132:2023 (identical text endorsed for European national standards).
