Heating Mantle Applications Across Key Industries
Chemical Industry
Provides uniform, high-temperature heating (~400 °C) for distillation, refluxing, extraction, crystallisation, and sample digestion.
Applications:
Organic synthesis – temperature control in esterification, nitration, polymerisation.
Distillation & reflux – stable boiling and solvent separation.
Quality control/testing – digestion for titration or elemental analysis.
Pharmaceutical R&D
Ensures precise heating for API development and natural extract research, commonly used in R&D and QC labs.
Applications:
Small-scale synthesis/screenings – digital mantles with stirring, multi-flask setups (e.g., 4-position).
Plant extraction/Soxhlet – uniform heating avoids scorching bioactives.
Reflux & purification – supports recrystallisation and purification processes.
Food & Beverage
Used in controlled heating for quality and safety testing, with uniform heating that prevents hot spots and sample scorching.
Applications:
Flavour/essential oil extraction – precise distillation of volatile compounds.
Quality analysis – digestion for fat/protein content, volatile acidity measurement.
Fermentation studies – gentle heating for microbial/enzyme activity.
