Cooling positions of SpeedDigester K-439
The side position shown in the drawing below is only applicable for 300 ml and 250 ml sample tubes
and racks. Due to the larger diameter of 500 ml sample tubes the glassware does not fit between rack
and housing. Racks with 500 ml sample tubes must not be installed in this position (see illustration)!
300/250 ml rack in side position
(DO NOT USE THIS POSITION FOR 500 ml RACKS / TUBES)
Note
A color change takes place during the cooling. At this time, the sample is still too hot to proceed!
•
Digested samples which are left undistilled over a long period tend to solidify.
•
If this happens:
➥ Carefully add a small quantity of distilled water
➥ Alternatively: Slightly warm up the sample in the SpeedDigester again
