Hotblock® Temperature Information - Environmental Express SimpleDist C6000 Operation & Instruction Manual

SimpleDist: Operation and Instruction Manual
HotBlock® Temperature Information:
The pre-set factory "set point" temperature of your HotBlock® is 106°C. Factory tests have shown that this temperature is "sea
level safe." Liquids in uncovered polypropylene tubes should not boil at this setting. Please note that the set point of the block
is not the same as the temperature of the liquids being digested. The block temperature should be optimized for the specific
digestion. The temperature of liquid contents of the digestion cup will vary according to:
• The material being digested
• The number of samples being digested
• The air movement of the digestion area
• The addition of a watch glass or reflux cap
If watch glasses are being used, the control point temperature should be lowered approximately 10°C to avoid boiling.
Note: The maximum sample temperature tolerance for our polypropylene digestion vessels (SC475) is 130°C.
Remember that the temperature display (current block temperature) is not the temperature of the sample. Sample temperature
will usually be 5-15° less than the display temperature.
Adjusting the Temperature of Your HotBlock®:
1. Plug the HotBlock® into an approved receptacle. Turn the HotBlock® on by pressing the button on the back of the unit.
Wait until the display shows the current block temperature (in red) and the set point temperature (in green).
Press and hold or tap the  or  key. The display will show the set point temperature on the right in blue. The
2.
adjustment is from ambient to 150°C in increments of 0.1°C. There is no need to press the green (advance) or ∞ button.
Safe-Sample™ Temperature Protection:
Your HotBlock® is protected from runaway temperatures by a fail-safe alarm system. In the unlikely event that the heating
system fails to respond to the controller, the Safe-Sample™ system will automatically shut the system off and sound an audible
alarm.
This alarm sequence occurs if the actual temperature of the block reaches a temperature that is fifteen degrees higher than
the set point temperature. If this should occur, the HotBlock® will stop heating, preventing the loss of samples. The HotBlock®
must be turned off, then turned back on to reset the alarm.
If the alarm sounds, see the HotBlock® troubleshooting guide of your manual on pages 20-22.
