Multi Tube / Pre-Heat Furnace – TMTH14 Series (Up to 1400 °C)

The TMTH14 Series Multi-Tube/Pre-Heat Furnace is a versatile, energy-efficient laboratory furnace designed for baking fluxes, crucibles, and samples before analytical testing. The controlled baking process removes moisture and surface contaminants absorbed during storage, reducing blank values and significantly improving measurement accuracy and precision.

With its multi-tube configuration, the TMTH14 allows up to four crucibles to be processed simultaneously, increasing productivity by up to four times compared to single-tube systems. Precise temperature control and uniform heating ensure consistent and reliable results across a wide range of analytical applications.

Improved Accuracy Through Pre-Heating

Pre-heating crucibles, samples, and fluxes stabilises analytical results by eliminating volatile impurities and moisture. The TMTH14 series delivers repeatable heating profiles, helping laboratories achieve greater consistency, reduced variability, and improved analytical confidence.
