Eco-Heat, Heating Mantle, 250 mL, 1 Each

The United Scientific® Eco-Heat, Heating Mantle by United Scientific heats round-bottom boiling flasks up to 250 mL from ambient temperature to 380 °C. A woven glass fiber mantle over an E-glass fiber core spreads heat evenly around the flask, and a continuous rotary knob sets the temperature. Organic chemistry teaching labs and small-scale preparation benches use it for reflux and distillation.
