Hei-VAP Core Rotary Evaporator Manual Lift 1 L

The Hei-VAP Core rotary evaporator is a professional laboratory solution for evaporation, concentration and vacuum distillation processes. This configuration features a manual lift and diagonal condenser with a cooling surface of 1400 cm², combining practical operation with accurate control of the main process parameters.

A clear digital display allows the operator to monitor current values, while a separate button displays the set values. Two independent control knobs are provided for adjusting rotation speed and heating temperature. LED light rings around the controls provide an immediate visual indication of active functions.

The rotation speed can be adjusted from 10 to 280 rpm, while the heating bath operates from room temperature up to 210 °C. An activated lock function prevents accidental changes to the selected settings. For improved operational safety, the unit also features a residual heat indicator for temperatures above 50 °C.

The immersion depth can be easily adjusted up to 155 mm, while the inclination angle of the evaporating flask can be set between 20° and 80°. Ergonomically designed heating bath handles provide a secure grip during positioning and handling.

Innovative sealing technology enables grease-free operation, simplifying routine use and maintenance. The ventilation cap features a PTFE inlet and is designed without ground joints. A filling valve is available as an option. An optional cable extension also allows the operating panel to be removed and positioned outside a closed fume hood.

The standard supply includes an Easy-Clip flask clamp, vapor tube, ventilation cap, heating bath, 1 L receiving flask, 1 L evaporating flask and diagonal condenser. The electrical supply is 230 V and the maximum heating bath volume is 4.5 L.

FAQ – Hei-VAP Core Rotary Evaporator

• What is the Hei-VAP Core rotary evaporator used for?

The Hei-VAP Core rotary evaporator is designed for laboratory evaporation, concentration and distillation processes, typically in combination with a vacuum system. Rotation of the evaporating flask increases the liquid surface area available for evaporation, while the heating bath supplies the thermal energy required for the process. The generated vapor is directed towards the condenser, where it is cooled, condensed and collected in the receiving flask. Rotary evaporation is widely used in chemical, pharmaceutical, cosmetic, food, university and research laboratories where controlled solvent removal, sample concentration or distillation is required.

• What rotation speed and heating temperature does the Hei-VAP Core provide?

The rotation speed is adjustable from 10 to 280 rpm, allowing operating conditions to be adapted to the sample and application. The heating bath can operate from room temperature up to 210 °C. Rotation speed and heating temperature are controlled independently using two separate knobs with LED light rings that provide visual operating feedback. The digital display shows the current values, while a dedicated button allows the operator to view the selected set values. A locking function helps prevent unintended changes during operation.

• What is the purpose of the 1400 cm² diagonal condenser?

The diagonal condenser is designed to cool the vapor produced during evaporation so that it condenses and can be collected in the receiving flask. This Hei-VAP Core configuration provides a 1400 cm² cooling surface. The condenser therefore plays an essential role in the rotary evaporation process, working together with the rotating evaporating flask, heating bath and, when used, the vacuum system to support controlled evaporation and recovery of condensed vapor.

• How does the manual lift work on the Hei-VAP Core rotary evaporator?

This Hei-VAP Core configuration features a manual lift system that allows the operator to position the evaporating flask relative to the heating bath. The immersion depth can be adjusted up to 155 mm, while the flask inclination angle can be set between 20° and 80°. These adjustments make it possible to adapt the position of the evaporating flask to different operating requirements. The ergonomically designed heating bath handles also provide a secure grip during normal laboratory handling and adjustment operations.

• What is included with the Hei-VAP Core manual lift rotary evaporator?

The standard package includes the main components required for the rotary evaporator configuration: Easy-Clip flask clamp, vapor tube, ventilation cap, heating bath, 1 litre receiving flask, 1 litre evaporating flask and diagonal condenser. The ventilation cap features a PTFE inlet, while a filling valve is optionally available. An optional cable extension can also be used to remove the operating panel from the main unit and position it outside a closed fume hood, providing greater flexibility when the evaporator is installed inside a laboratory extraction enclosure.
