Heating Mantle (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.

LCD Digital Heating Magnetic Stirrer (MS‑H280‑F250)

LCD digital heating magnetic stirrer (MS‑H280‑F250) with interchangeable 250 mL round-bottom flask mantle (89.75 mm ID); adapts to 100/250/500/1000 mL F-series flasks and B-series beakers. Three modes: heating/stirring, detached 20 L magnetic stirrer on Ø135 mm ceramic-coated plate, or Two-in-One independent heating and stirring. LCD shows temperature, speed, and timer (1 min–99 h 59 min); brushless DC motor; PT1000 sensor (±0.2°C); auto temperature calibration. Safety: dual over-temperature circuits (420°C cutoff), HOT warning >50°C even unplugged, flask-position detection, fire-resistant metal housing, IP21; TÜV CE/cTUVus/FCC.
