A Digital Metal Bath, also known as a Dry Block Heater or Laboratory Metal Bath, has become an essential piece of equipment in modern laboratories worldwide. Compared with traditional water heating methods, digital metal baths provide higher temperature accuracy, faster heating speed, improved safety, and a broader range of laboratory applications.
What Is a Digital Metal Bath (Dry Block Heater)?
A Digital Metal Bath is a laboratory heating device that uses solid aluminum heating blocks instead of water to heat samples. Test tubes, centrifuge tubes, vials, and microplates are placed directly into precision-machined holes, allowing uniform and efficient heat transfer.
Key Characteristics of a Laboratory Metal Bath
- Water-free heating system
- Digital temperature control
- High temperature stability
- Minimal maintenance requirements
Why Choose a Digital Metal Bath Instead of a Traditional Water Bath?
Faster Heating and Improved Efficiency
Aluminum’s high thermal conductivity allows a digital metal bath to heat samples much faster than water baths, improving laboratory workflow efficiency and reducing experiment waiting time.
Wider Temperature Range
While traditional water baths are limited to approximately 100°C, GLTlab Digital Metal Baths offer standard models up to 200°C and high-temperature models up to 300°C, enabling advanced laboratory applications.
