DRIERITE Desiccants for Laboratory, Packaging and Industrial Drying
DRIERITE desiccants are anhydrous calcium sulfate-based drying agents used to remove moisture from air, gases, organic liquids, solids, storage spaces and sealed packages. J&K Scientific offers DRIERITE® products in multiple forms and mesh sizes to support laboratory drying, sample protection, gas purification, packaging protection and moisture-sensitive material handling.
As a versatile desiccant, DRIERITE® is commonly selected when users need fast moisture removal, low residual humidity and stable performance in controlled drying environments. Depending on the application, customers may choose regular DRIERITE®, Du-Cal DRIERITE®, commercial grades, indicating products or packaged desiccant formats.
What Is DRIERITE®?
DRIERITE is a calcium sulfate desiccant designed for efficient moisture absorption. Regular DRIERITE® is based on anhydrous calcium sulfate and is widely used where chemical inertness, low dusting, dimensional stability and reliable drying performance are important. It is suitable for many laboratory and industrial applications involving moisture-sensitive materials.
Typical Applications
- Drying air and common laboratory gases
- Maintaining low humidity in desiccators, storage cabinets and sealed enclosures
- Protecting hygroscopic chemicals, reagents and moisture-sensitive materials
- Drying selected organic liquids and solids in laboratory workflows
- Moisture control in commercial packaging, instruments and electronic components
- Use in drying tubes, gas drying towers, vent driers and packaging systems
How to Choose the Right DRIERITE® Product
| Product Type |

Selection Notes |
| Regular DRIERITE® |
General laboratory drying, gases, storage and desiccators |
A good choice when chemical inertness and consistent drying performance are required. |
| Du-Cal DRIERITE® |
Air and common gas drying where higher capacity is needed |
Designed for applications where moisture capacity is more important than maximum chemical inertness. |
| Commercial DRIERITE® |
Industrial drying, organic liquid drying and polymer-related applications |
Useful for larger-scale or process-oriented drying requirements. |
| Indicating DRIERITE® |
Visual monitoring of desiccant activity |
Provides a visible color change to help indicate when replacement or regeneration may be needed. |
| DRIERITE® Desiccant Bags |
Packaging, shipping and sealed container protection |
Convenient for protecting instruments, materials, electronics and packaged goods from humidity. |
Mesh Size Selection Guide
Mesh size affects flow resistance, contact area and handling characteristics. Finer grades are often selected when close contact with liquids or small spaces is needed, while larger granules are commonly used in drying tubes, towers, desiccators and airflow systems.
| Mesh / Form |
Typical Use |
Practical Consideration |
| Powder / fine mesh |
Drying liquids or applications requiring high surface contact |
May require filtration or careful handling after use. |
| 20–40 mesh |
General laboratory drying and packed drying systems |
Balances surface area and manageable flow characteristics. |
| 8 mesh / 6 mesh / 4 mesh |
Drying tubes, gas drying towers, desiccators and larger drying beds |
Larger granules reduce pressure drop and are easier to handle. |

Frequently Asked Questions
What is DRIERITE® used for?
DRIERITE® is used as a desiccant for drying air, gases, organic liquids, solids and sealed environments. It is commonly used in laboratories, desiccators, drying tubes, packaging protection and moisture-sensitive storage applications.
What is DRIERITE® made of?
Regular DRIERITE® is based on anhydrous calcium sulfate, a solid drying agent that absorbs moisture and helps maintain a dry environment.
What is the difference between Regular DRIERITE® and Du-Cal DRIERITE®?
Regular DRIERITE® is generally selected for broad drying applications where chemical inertness is important. Du-Cal DRIERITE® is designed for air and common gas drying where higher moisture capacity is required.
Which mesh size should I choose?
Fine mesh products are useful when high contact area is needed, while larger granules such as 4 mesh, 6 mesh or 8 mesh are commonly used in drying tubes, towers, desiccators and airflow applications.
Can DRIERITE® be regenerated?
Many DRIERITE® products can be regenerated for reuse, depending on the product type, use conditions and safety considerations. Always follow the applicable SDS and product handling instructions.
