Basic safety instructions Basic safety instructions The rotary evaporator is constructed according to the current state of the art and accepted safety regulations. However, risks still exist during the installation, operation and maintenance of the product. Observe safety instructions and warnings. The basic safety instructions in this chapter are supplemented in the following chapters of the operating instructions by concrete warnings.
Basic safety instructions Basic safety instructions Responsibilities of the operating personnel Verify that the distillation material can be evaporated safely and that the distillation residue is not explosive. Verify that work using an open flame is not conducted in the surroundings of the rotary evaporator (explosion risk). Verify that the flow rate of < 1 m/s is guaranteed when suctioning liquids that contain combustible materials (electrostatic charge; ignition risk).
Basic safety instructions Basic safety instructions Signs on the equipment Sign WARNING Danger of slipping! Risk of injury. Designation The floor near the machine may be dirty after the operation or during malfunctions in the machine. Water from the bath may spill or condensation from coolant may drip on to the floor near equipment. Watch for contaminated areas and clean the floor, if necessary. Hot surface Risk of entanglement WARNING Hot surfaces! Scalding and burns.

Operation Operation Operation of the Hei-VAP Precision The basic steps of operating the rotary evaporator Hei-VAP Precision will be explained in this chapter. The parameters for the distillation are set and monitored via the control panel. The set parameters are stored. The last used parameters will appear after a restart. The actual value display is always the start screen. All current actual values are displayed as large numbers and the target values as small numbers.
Operation Operation Setting the rotation speed (actual value displays of all modes) The unit is switched on. The rotation is switched off (pushbutton Rotation start/stop). Actual value display The range can be set from 10 - 280 [rpm] in 1 [rpm] increments. 100 [rpm] are set as default when shipping from the factory. 1. Select the entry “rotation” by turning the Hei-GUIDE (6) and call up the selected entry to be changed by pressing the Hei-GUIDE (6) again. 2.
Operation WARNING Operation Imploding glass devices!! Selecting the entry by turning the Hei-GUIDE (6) Serious injuries from shattering glass. 1. Call up the selected entry to be changed by pressing the Hei-GUIDE (6) (entry will be highlighted in orange). 2. Set the value by using the rotary pushbutton controller Hei-GUIDE (6). 3. Pressing it again confirms the change. Softkey “Esc“ (1) terminates the change of the currently processed entry. 4. The new settings are accepted by the “accept” entry.
Operation Operation Actual value display Autoeasy mode The required vacuum is automatically calculated based on a pressure measurement in the “AUTOeasy” mode. The boiling pressure is detected and maintained automatically. The “AUTOeasy” mode is configured for easy handling and for common heating bath and cooling media temperature. In case the amount of steam produced is insufficient and the evaporation does not start, increase the heating bath temperature.
Operation Operation Menu display The following values can be changed in the menu view: Heating bath Setting of the bath temperature. Setting range is between 20 °C and maximum heating bath temperature (MAX TEMP is adjustable in Setup) with a highest range of 210 °C. Rotation Setting of rotation speed of the distillation flask. Setting range is between 10 and 280 rpm. Distillation rate (dT) Setting of the distillation rate. Setting range is between 1 and 10.
Operation Operation Timing functions Storing the data record The vacuum control is not activated. Parameters are set. You are in the menu view of a mode (SETpressure, AUTOeasy, AUTOaccurate, gradient) Press softkey “Store Favorite“. The timer function stops the distillation after a set period. The setting range is adjustable from 1 - 1440 [min] in 1 minute. increments in the “timer” menu entry. Setting “off” is comparable to 0. The entry is set to lowercase letters with element “abc”.
Operation Operation Rename the data record The following values can be changed in the menu view: The name can be entered similar to the “save” function. The system checks for duplicates when naming. Heating bath Setting of the bath temperature. Setting range is between 20 °C and maximum heating bath temperature (MAX TEMP is adjustable in Setup) with a highest range of 210 °C. Copy data record Rotation Setting of rotation speed of the distillation flask. Setting range is between 10 and 280 rpm.
Operation Operation 1. Select the pressure/time step to be changed by turning the rotary pushbutton controller Hei-GUIDE (6). 2. Confirm the selection by pressing the Hei-GUIDE (6). 3. The value can be changed by turning the Hei-GUIDE (6) to the left or right. 4. The current setting is accepted by pressing the Hei-GUIDE (6). The data record can be saved by using softkey “Store Favorite“ (1). Softkey “Esc“ (1) discards the changes and returns to the actual value display.
