Heating of the HunterLab Sample Cup

FAQ: “Can the sample cup be filled with sample and heated?”

Our regular sample cup (HL# 04-7209-00) has a robust construction where the flat bottom window and cylinder that make up the cell are melted into one another at the seam. The sample cup with contents will withstand gradual heating without ill effects.

Use only a heating mechanism such as a water bath or forced air furnace to gradually heat the cell and contents to the target temperature.

Heating the cell and contents on a direct heat source such as a thermal hot plate or Bunsen burner is not recommended.

Water baths will take samples up to 100 degrees Celsius (212 degrees Fahrenheit) and this can be done repeatably without ill effects to the cell.

If this is just an occasional test, our regular cells can withstand higher temperatures up to 150 degrees Celsius (302 degrees Fahrenheit) if there are no sharp temperature gradients during the heating process.

Please note that continual heat cycling at levels above 100 degrees C will eventually cause the cell to crack at the seam where the flat bottom meets the side. We suggest keeping a spare cell available if continual heating is the standard practice.
