Leading safety standards – Intelligent Distillation

• 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 enables convenient handling from outside 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 innovative ventilation and replenishment valves no longer have ground joints, which enables maximum tightness and grease-free operation
• 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
• All components in direct or indirect contact with the medium are equipped with FDA-compliant materials for an extended application range

Reduced cost of ownership

• Achieve significant higher evaporation rates due to unique tightness and industry-leading condensing surface of 2.200 cm2 with the XL condenser
• The high resistant and durable FKM vacuum seal achieves maximum tightness and reduces spare part budgets
• 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 (Polyphenylene sulfide), a robust industrial-designed resin with superior chemical resistance which provides more chemical resistance than stainless steel or welded aluminum. This reduces corrosion to a minimum which results in additional savings on maintenance and replacement components
• 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
• Maintenance-free and non-sparking motors reduce repairs and down times significantly to ensure years of continuous operating
• Spend your working hours more effectively on other challenges which require your attention and evaporate large quantities continuously with the automatic module Distimatic Bench-top
• Maximize your initial investment significantly: the automatic module Distimatic Bench-top is an affordable and more flexible alternative to large-scale rotary evaporators

The Hei-VAP series provides the mentioned advantages, a 3 year warranty and an average 10 year operational lifespan - this makes your purchase a worthwhile investment

The Hei-VAP devices with hand lift are optimally suited for all standard applications. Controlling parameters is done so with the simple turn of a knob

• 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

All glassware assemblies are also available with completely transparent synthetic coating (order number "coated"). The scope of delivery comprises one 1,000 ml evaporation and one 1,000 ml receiving flask each in standard cut NS 29/32. Other versions available on request.
