5.4 Concentration
The prerequisite for all applications described here is the previously described preparation
(see Preparation for concentration on p. 27).
5.4.1 Concentration with time setting
Perform the following steps in the sequence described.
1. time arrow keys: set run time.
2. brake: switch brake on or off.
3. temp: select temperature (observe temperature resistance of the samples).
4. mode/vent: select V-AQ, V-AL or V-HV mode.
5. start/stop: start concentration.
• The device lid is locked, and the green lid indicator lamp goes out.
• The rotor starts up.
• At 1,000 rpm, the vacuum pump switches on, and the vac indicator lamp lights up.
• The vent valve is closed.
• The rotor accelerates to the end point of 1,400 rpm.
• On the display, the colon of the time display flashes while the rotor is turning.
• The remaining run time is displayed in hours and minutes.
WARNING!
Risk of injury from improperly attached rotors.
 Only operate the device if the rotor has been mounted completely.
 If there are any unusual noises when the device is started up, immediately press the start/
stop key to stop concentrating.
CAUTION!
Risk from incorrectly loaded rotors and damaged/overloaded tubes!
 Before commencing concentration, follow the safety instructions relating to risks from
unsymmetrically loaded and/or overloaded rotors and from overloaded and/or damaged tubes
(see Warnings for intended use on p. 15).
NOTICE!
Overflowing of the emission condenser.
The maximum filling volume of the emission condenser is 280 mL.
1. Check before each run whether the volume of the emission condenser is sufficient for your
application.
2. Empty the emission condenser, if required (see Emptying the emission condenser on p. 32).
Hint!
Unusual noises may occur when braking heavy rotors. These noises are due to the design and
do not indicate problems.
