Heidolph Rotary Evaporator Hei-VAP Expert Control motor lift

Heidolph Rotary Evaporator Hei-VAP Expert Control motor lift

Adds numerous smart features to the Hei-VAP Expert, as well as an overview of all parameters and the current process

• 5'' touch display for controlling the entire system including the vacuum and the cooling temperature
• For precise monitoring, the pictogram on the display also symbolizes active functions
• Separate knobs for quick access: the right one for direct vacuum control, the left one for the rotation
• Setting of values either via the touch display or the separate quick access knobs
• Direct access to two favorites on the start screen
• Expandable solvent library. You can also transfer your own favorites to other devices using a USB stick
• Define and save own evaporation processes (ramps)
• Automatically evaporate with the Dynamic AUTOaccurate Program (DAA). Convenient and customizable: from foam avoidance to highly efficient evaporation
• With USB and Micro SD interface for easy installation of software updates and transfer of individual favorites from one device to another

The Hei-VAP Control principle
Hei-VAP Expert Control and Ultimate Control allow to centrally control all process parameters: vacuum, cooling temperature, rotation and heating bath temperature.

Evaporate with a tap:

• Customizable solvent library
• Automatically find boiling points with Dynamic AUTOaccurate
• Simply save processes as favorites

Automatic evaporation with Dynamic AUTOaccurate (DAA)
The DAA allows you to start a fully automated distillation process already during the heat-up phase of the heating bath.
The system vacuum is dynamically adjusted to the changing heating bath temperatures until the heating bath has reached its defined temperature.

• The boiling points of one or more fractions are identified through the steam temperature gradation of the mixture during continuous automatic pressure control
• You can freely set whether one or more fractions are to be distilled. The vacuum control is fully automated for each fraction
• You can control the evaporation speed by adjusting the ratio of steam temperature to cooling temperature
• Samples are distilled precisely
• Automation with sensors ensures noticeably higher precision
• To protect your sample, motor lift models automatically remove the evaporating flask from the heating bath at the end of the process

Leading Safety Standards

• All Hei-VAP rotary evaporators have a safety heating bath with overheating and dry running protection, ergonomic handles, double wall and an integrated spout
• Digital displays allow continuous monitoring of the current values and, thanks to protection class IP 42, protect the electronics reliably against dripping water and dust
• The locking function of the knobs prevents unintentional adjustment of the values
• The standby button stops all functions and lifts the evaporating flask from the heating bath
• Additional safety from a single source: From the transparent plastic coating of the glassware to guard shield and guard hood (implosion protection) to IQ-OQ documentation and certification
• Universal heating bath for all flask sizes up to 5 l (no retooling required). The sturdy metal connection to the device's base allows variable distances for the heating bath up to 200 mm without tilting
• Separate knobs with intuitive LED ring light system not only allow visual process control, but also direct intervention in the evaporation process at any time
• Residual heat indicator: When the function is deactivated and in standby mode, flashing and the display of the residual heat warn of the risk of burns (> 50 °C)
• In order to prevent short circuits and corrosion systematically, the cable connections of the operating panel and the heating bath comply with the high protection class IP 67

Superior Ease of Use

• Models are available with motor lift
• The versatile operating concept meets all requirements with digital display or touch display
• The detachable panel with optional extension cable and holding device allow quick and easy operation even outside closed fume hoods
• FDA-compliant materials for all active and passive media-contacting components permit a broader range of application and research at the highest level
• The optionally available automatic module Distimatic permits fully automatic distillation in unattended continuous operation
• The patented flask clamp Easy-Clip facilitates attaching and changing of the evaporating flask. The mechanism gently separates ground glass joints to prevent glass breakage
• Intuitive operation, as all settings are configured centrally on the operating panel. In combination with the Control-Box, the panel can even be used as the central control unit to regulate the vacuum and the Hei-CHILL recirculation chiller as well
• Easy ventilation thanks to the ground-free condenser design: The ventilation cap with PTFE inlay and threaded connection avoids stuck glass - without grease. Optionally, a venting valve with refill function is also available
• Convenient release for individual adjustment of the angle of inclination from 20° to 80° and height stop to limit the immersion depth up to 160 mm

Reduced Cost of Ownership

• No unnecessary additional costs: The patented clamping sleeve effectively prevents the vapor tube from getting stuck in the drive
• Ground-free condenser design with grease-free threaded connections
• The unique tightness of the vacuum system leads to shorter process times, reduced energy costs and purest results
• Even greater efficiency with up to 40% higher evaporation rates: The intelligent design of the XL condenser provides 57% more cooling surface at almost the same height as previous standard vertical condensers
• Media-contacting plastic parts such as the screw connection for mounting the condenser and the clamping sleeve on the vapor tube are made of highly resistant PPS to ensure a long lifespan
• With the patented Easy-Clip's integrated screw thread, stuck evaporating flasks can be released safely and easily
• The highly resistant and particularly durable PTFE vacuum seals achieve maximum tightness and reduce expenses for spare parts in the long run
• The universal heating bath is suitable for all flasks up to 5 l, without additional costs for retrofitting
• Quality that pays off. Corrosion-free die-cast housings with condensation-repellent varnish and maintenance-free motors guarantee unrestricted continuous operation and a long lifespan with significantly lower maintenance costs
• Many of the current series' spare and wear parts are forward and backward compatible with earlier models
