Turning the steam distillation
apparatus on
Preparations
Acids and bases can cause burns and
other injuries!
In working with acids and bases, observe
the safety precautions prescribed for these
substances in the Material Safety Data
Sheets!
Fill the reagent containers with the appropriate chemi-
cals.
Verify by checking the tubing connections which rea-
gents are to be filled into which containers. Then fill the
containers accordingly:
Distilled or deionized water (e.g. from a behropur
®
water deionizer)
NaOH, 32%
H
3
BO
3
, 2 - 4%
If it has not yet been done, empty the waste-water
container, disposing of the contents in accordance to
regulations.
Provide the cooling water supply
Open the water tap.
Switching the S 5 on
Turn the power on by switching the MAIN SWITCH
(3.15) on the front of the S 5 to the position „I“.
The electrical power switch of the S 5 fulfills two func-
tions. It serves to turn the apparatus on and off and
also has an electrical circuit-breaker built in.
This circuit breaker operates on a similar principal to
those used in homes. If too much current is drawn, it
shuts off.
The operation of this circuit breaker requires that a
spring within it be cocked. For this reason, a some-
what greater pressure is required on the switch to
turn it on than is required in a similar switch without
circuit breaker.
Switch your titration unit and - if installed - your printer
on.
After turning the apparatus on, the display on the front
will briefly show an initialization notification. Immediately
thereafter, the pump begins filling the steam generator
and you see the following notification on the display:
steam generator filling
An hourglass symbolizes the ongoing process.
Next, the following notification appears:
steam generator heating
Again, the hour glass is seen on the display.
These two procedures can take a bit of time, especially
when the apparatus is switched on for the first time.
These procedures have been completed when the dis-
play switches to the „Start“ mode
The S 5 steam distillation apparatus is now ready for
operation.
