DLAB HF250

The Heating Mantle for 250mL Round‑bottom Flask (HF250) is a dedicated, form‑fitting electric heating mantle engineered for safe, uniform, and efficient heating of 250 mL round‑bottom flasks in pharmaceutical research, chemical synthesis, analytical chemistry, and educational laboratories. With a precision‑machined inner diameter of 89.75 mm for optimal thermal contact, this heating mantle provides a maximum temperature of 450 °C and a typical power consumption of 150 W, making it ideal for distillation, reflux, solvent evaporation, and general laboratory heating applications.

 Heating Mantle for 250mL Round‑bottom Flask (HF250) features a robust fiberglass heating chamber embedded with nichrome heating wire, providing excellent heat exchange and uniform temperature distribution across the flask surface. The fiberglass mesh insulation minimises heat build‑up on the outside surface, keeping the external housing at a safe temperature and protecting the user from burns while also enhancing thermal efficiency for energy conservation. The precisely contoured 89.75 mm inner diameter perfectly matches 250 mL flask dimensions, delivering optimal thermal contact and reliable performance for various laboratory heating applications requiring flask‑based setups.

Key user‑focused features include uniform heat distribution across the flask wall which prevents localized overheating and ensures reproducible results; fiberglass insulation that keeps the external housing at a safe temperature; chemical and thermal resistant housing that withstands laboratory spills; and a precisely contoured design that securely holds the flask in place while providing clear visibility of the top half of the flask during operation. The hemispherical heating chamber maintains direct contact with the glassware for efficient heat transfer.

For the research scientist, pharmaceutical chemist, and laboratory technician, the Heating Mantle for 250mL Round‑bottom Flask (HF250) delivers the safe, uniform, and efficient heating required for chemical synthesis, distillation, reflux, extraction, and sample digestion. For the patient, reliable and reproducible heating ensures that pharmaceutical research, clinical testing, and educational training are conducted with consistent and accurate thermal conditions, directly supporting effective drug development, reliable diagnostic protocols, and the training of future medical laboratory professionals.
