Heating and Cooling in a Compact Laboratory Unit
The MDB series is available in two operating configurations.
MDB heating model: Designed for applications requiring controlled heating without active cooling.
MDB-C heating and cooling model: Uses semiconductor refrigeration without a gaseous working medium, providing both heating and cooling functions in one compact laboratory instrument.
This makes the MDB-C particularly useful when laboratory workflows require temperature adjustment in both directions.
Replaceable Aluminium Heating Blocks
The dry bath uses a replaceable aluminium thermal block, allowing the instrument to be configured for different tube sizes and capacities.
Available MDB/MDB-C blocks include:
| Module | Tube Format | Capacity |

What Makes the MDB-C Different?
The MDB-C heating and cooling dry bath incubator provides a wider temperature-control capability than the heating-only MDB model. It combines controlled heating with semiconductor refrigeration and can operate from room temperature −15°C to 100°C.
Choose MDB-C when your application requires both heating and active cooling. Choose MDB when controlled heating is sufficient.
