Determine the water bath temperature
The temperature of the sample vials depends on several factors, including the
ambient temperature of the air around the tray and the temperature of the water
bath.
Caution If the sample temperature is critical for accuracy, experiments should be
performed to validate water bath settings. Actual heat transfer varies with vial
material, humidity, condensation on the vial, and flow rates.
Use the chart in Figure 13 to determine the water bath temperature.
