HF250

Heating mantle  (HF250) with a precision-machined 89.75 mm inner diameter for optimal thermal contact. It's for 250 mL round-bottom flask. Maximum temperature 450°C, typical power 150 W. Fiberglass heating chamber with nichrome heating wire and fiberglass mesh insulation for uniform heat distribution and a safe external housing temperature. Chemical- and thermal-resistant housing; hemispherical chamber maintains direct contact with the flask for efficient heat transfer, securely holds the flask, and keeps the top half visible. Ideal for distillation, reflux, solvent evaporation, chemical synthesis, extraction, and sample digestion.
