Overview
ISO 13130:2011 - Laboratory glassware - Desiccators defines the international requirements and test methods for desiccators and vacuum desiccators intended for general laboratory use, especially for the drying of substances or materials. Created by the International Organization for Standardization (ISO), this standard ensures that desiccators meet fundamental quality, performance, and safety expectations for laboratories worldwide. ISO 13130:2011 addresses two main types of desiccators: vacuum and non-vacuum, and provides clear guidance concerning materials, construction, design, dimensions, marking, and thermal shock endurance.
Key Topics
-
Scope and Purpose
ISO 13130:2011 applies to laboratory desiccators designed for drying applications, setting specifications for both vacuum and non-vacuum types.
-
Desiccator Types and Classification
- Type 1: Vacuum desiccators
- Type 2: Non-vacuum desiccators
The standard covers multiple sizes and series (Series A and Series B) with detailed dimension tables.
-
Material Requirements
- Desiccators must be manufactured from borosilicate glass 3.3, as specified in ISO 3585.
- The glass must be free from defects and residual strain, and may be brown-tinted to protect sensitive substances.
-
Design and Performance Criteria
- Symmetry, smooth finishes, and robust construction
- Concave bases and stepped sides for stability
- Interchangeable vacuum-tight flanges
- Rigorous vacuum integrity with strict leakage thresholds
- Pressure strength testing defined (withstand external pressure of 2 bar for 60 seconds, or 3 bar for 10 seconds)
- Thermal shock resistance to 80°C
-
Marking and Packing
- Permanent marks indicating manufacturer, size, type, and optionally standard reference
- Individual packaging to ensure transit protection
-
Inspection and Safe Use
- Visual checks of used desiccators for chipping, cracks, and other damage before each use
Applications
Desiccators compliant with ISO 13130:2011 are essential in diverse laboratory environments, including:
-
Chemical and Analytical Laboratories
For the drying, storage, or protection of moisture-sensitive samples and reagents.
-
Biology and Life Science Labs
Safeguarding biological materials that require a dry atmosphere during experiments or storage.
-
Pharmaceutical and Quality Control
During sample preparation, storage, and analysis where humidity must be controlled.
-
Material Science Research
Used in testing the moisture content or stability of solids and powders.
ISO 13130:2011 assures laboratories and institutions that their equipment is consistent, reliable, and safe, supporting reproducible scientific procedures.
