Rotary Evaporators Hei-VAP Series

Leading safety standards

• Two independent safety circuits avoid an overheat situation of your heating bath: If bath temperature overshoots by 5°C and if your water bath runs dry heating will be switched off automatically
• To avoid an over temperature situation and potential thermal damage to your sample, you can pre-program on the Precision model a max. SET temperature individually at which the bath shuts off
• In case of a power-cut, all motor lift models will remove the flask from the heating bath preventing safety hazards and potential thermal damage to your sample
• To protect you from splashes and scalding, the Hei-Vap heating bath features a pour spout to remove bath fluid safely
• Heating bath is constructed with a double wall for your protection against burns and scalding
• The guard hood covers the entire bath completely even if the heating bath is adjusted horizontally to is most extreme limit
• To prevent short-circuits and systematic corrosion from your heating bath, the electrical cable couping complies with the high protection class IP 67
• For your protection the operating panel is located near the base and keeps your hands out of the dangerous zone of rotating flasks, steam and spashing bath fluids
• All heating baths feature non-slip handles with safety grip to protect you from scalding bath liquids and allow for easy installation / removal of the bath
• A separate on/off switch for heating prevents an unintentional heat up. If heating is switched on the on/off button is illuminated for visual control
• In case of an overshoot of any parameter setting, all models woll show a warning on the operating panel
• Glassware assemblies are optionally available with transparent plastic safety coating ensuring ultimate protection while allowing visual control at all times

Superior ease of use

• The detachable operating panel can be attached via velcro or with a special suspension at eye level for your convenience outside of closed fume hoods
• The integrated screwed ring allows you to remove sticking evaporating flasks from the vapor tube just in seconds in a safe manner
• The universal heating bath can be adjusted horizontally up to 200 mm and offers efficient space to accommodate even 5 liter flasks
• For your convenience the height of 160 mm and the angle of the evaporating flask can be adjusted easily from 20° to 80°
• The patented Easy-Clip provides an easy removal of sticking flasks and cannot get lost due to the direct connection to the vapor tube coupling ring

Reduced cost of ownership

• Reduce your process times up to 30%
• The chemically resistant PTFE vacuum seal reduces your spare parts budget up to 75% with prolonged operational lifespan
• The patented clamping sleeve ensures a long life performance of the vapor tube
• Increase your range of applications by using 5 liter flasks in the universal bath at no added costs
• The flange on the condenser side of the drive is made of PPS (Poly Phenylene Sulfide), a robust industrial designer resin with superior chemical resistance, and thus provides more chemical resistance than stainless steel or melded aluminium. That reduces corrosion to a minimum which results in additional savings on maintenance and replacement components associated with corrosion effects of moisture condensation from condenser coupled with common corrosive reagents used in daily laboratory activities
• Only Hei-Vap heating baths reach a temperature of 210°C which is 30°C higher than other evaporators on the market and allow for a broader range of applications which previously could not be performed on any rotary evaporator (for example bitumen distillation). Thus increasing the range of applications eliminates the need for investments in other equitment
• Continuous unattended evaporation without limits – the automatic module Hei-VAP Distimatic with automatic release of condensate is an affordable and more flexible alternative to large-scale rotary evaporators

• Use the USB connection to document reproducible results
• Now you can manage even the most demanding applications easily and prevent foaming, excessive bubbling or bumping
• Save time with your individualized pre-programmed parameter settings for your 30 most common applications on a daily basis by saving them in a "Favorites" section
• Each ramp offers 20 separate steps for demanding applications
• Apply an individual name to those ramps to avoid a mix-up
• Benefit from the timer function to terminate your application automatically
• Control your process individually by freely programming pressure gradients in gradient mode
• You do not need to invest in a vacuum controller as one is already integrated in your Precision model

Programs facilitate process control
Reduce your 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 you have the full flexibility to choose any other level of vacuum by the press of a button

AUTOeasy supports the 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. Also the AUTOaccurate program delivers the finest and most precise vacuum control. To take advantage of this program the optional AUTOaccurate-sensor is required.
Also this program can not be used on Heidolph G1 and G5 glassware assemblies. Leading parameter of this program is the vapor temperature
