Measure the temperature of the heating block
Measure the temperature of the heating block to make sure that the
temperature shown on the display is correct.
The temperature shown on the display is the temperature in a closed
sample cell that is filled with a liquid. While the temperature of the
heating block is increasing, the temperature of the heating block, near
the heater, may be greater than the temperature shown on the display.
Tools needed:
• Sample cell (2275800)
• Glycerol (anhydrous), 5 mL
• Thermometer, stem-type, calibrated for 95 to170 °C (203 to 338 °F)
To measure the temperature of the heating block:
1. Fill a clean, empty sample cell with glycerol that is at room
temperature.
2. Put the thermometer in the sample cell until the thermometer touches
the bottom of the sample cell.
3. Make sure that the level of the glycerol is 56 mm ± 0.5 mm (2.20 in. ±
0.02 in.) from the bottom of the sample cell when the thermometer is
in the sample cell.
4. Put the sample cell in the center opening of the second row of the
heating block.
5. Select a temperature program of 150 °C for 60 minutes using the
keys, then push OK.
6. When the heating block is at the selected temperature (two beeps
are heard), the thermometer temperature should be the same as the
temperature shown on the display.
