The Hei-VAP Precision, with built-in vacuum controller, provides users with the maximum range of parameters, including but not limited to, reproducible applications and fully automated processes. Even solutions with different boiling points can be identified and distilled.
- HL models with hand lift, ML models with motor lift
- All connected devices are automatically recognised by the evaporator, eliminating the need to configure the unit manually
- Individualised pre-programmed parameter settings for 30 of the most common applications can be saved in a 'Favorites' section
- Each ramp offers 20 separate steps for demanding applications
- Automatic process timer turns off the evaporator at a pre-programmed time by raising the flask and releasing the vacuum (ML models only)
- USB interface and integrated software support for easy data management
- Large colour graphic display for all parameters and automated programs
Suitable for the most demanding applications, with excellent integrated vacuum control capabilities.
210 °C safety heating bath, with handles and pour spout, will power off if temperature overshoots by 5 °C or runs dry.
Three program opportunities for automated distillation:
SETpressure: For solvent separations
This program holds a pre-set vacuum constant. During evacuation users have the flexibility to choose another level of vacuum by the press of a button. Optionally, the process can be pre-defined via programmable ramps.
AUTOeasy: Supports automatic pressure control for solvent separations
The pressure level for the first boiling point is found automatically. This program can be used with all Heidolph glassware assemblies and does not require any accessories.
AUTOaccurate: Supports very precise automatic pressure control for solvent separations
This program works similar to AUTOeasy but in addition is able to identify multiple boiling points automatically by reducing vacuum accordingly. AUTOaccurate also delivers the finest and most precise vacuum control. To take advantage of this program, optional AUTOaccurate-sensor is required. This program cannot be used on Heidolph G1 and G5 glassware assemblies. Leading parameter of this program is the vapour temperature.
Glassware set G1
Diagonal condenser for all standard distillations; option with the most affordable price.
Glassware set G3
Vertical condenser for all standard destillations; option with the smallest space requirements, also available as XL version (condensing surface of 2200 cm² for up to 40% higher evaporation rates).
Glassware set G5
Dry ice condenser for low boiling solvents.
Glassware set G6
Vertical condenser; centrepiece with valve for reflux distillation.
Reduce process times significantly by using these three programs for automated distillation:
SETpressure: Program for solvent separations. This program holds a set vacuum constant. During the evacuation the user has the full flexibility to choose any other level of vacuum at the press of a button.
AUTOeasy: Supports the automatic pressure control for solvent separations. The necessary pressure for the first boiling point is found automatically. This program can be used with all Heidolph glassware assemblies and does not require any accessories.
AUTOaccurate: Supports very precise automatic pressure control for solvent separations. This program works similarly to AUTOeasy, but in addition, is able to identify multiple boiling points automatically by reducing the vacuum accordingly. Also, the AUTOaccurate program delivers the finest and most precise vacuum control. To take advantage of this program the optional AUTOaccurate sensor (531-0844 see accessories) is required. This program cannot be used with Heidolph G1 and G5 assemblies.
