Hei-VAP Precision HL Rotary Evaporator with Manual Lift and G3 Glassware Set

The Hei-VAP Precision HL is the top-tier model in Heidolph's Hei-VAP series. Ultra-smooth manual lift, G3 glassware set included, and three automated distillation programmes for solvent removal with vapour temperature and pressure control. Declared time saving of over 30% compared with conventional rotary evaporators.

System Features

• Lift: Ultra-smooth manual (HL model) with selector for flask immersion depth
• Motor: Silent; electronic speed regulation from 20 to 280 r.p.m.
• Vacuum seal: PTFE with graphite filling — grease-free, long service life, resistant to corrosive vapours
• Vapour tube: 26 mm Ø hollow shaft for increased vapour flow; special-fit cone prevents jamming
• Flask ejector: Included as standard for cases of evaporation flask seizure
• USB connection: For data logging and control

Heating Bath

• Volume: 4.5 litres (Ø 25.5 cm)
• Temperature range: 20 to 210 °C
• Accuracy: ±1 °C
• Safety thermostat: Overtemperature protection
• Vessel: Stainless steel 1.4404 / AISI 316L — corrosion-resistant; no internal spiral heating elements for ease of cleaning
• Construction: Insulated wall and non-slip handles for safe handling

Control Panel and Distillation Programmes

Integrated 4.3'' LCD display with real-time readout of rotation speed, bath temperature, vapour temperature and vacuum. Detachable panel for remote operation up to 1.3 m.

Three automated distillation programmes:

• SET_pressure: Maintains constant vacuum pressure. Pressure can be adjusted during evacuation with a single keypress.
• AUTO_easy: Automatic pressure control with automatic detection of the solvent's first boiling point.
• AUTO_accurate: Automatically identifies multiple boiling points and adjusts vacuum accordingly. Requires G3 or G6 glassware set and the AUTO_accurate probe as accessories. Vapour temperature is the primary control parameter.
