Dickson's Glass Bead Bottles are a great way to stabilize your temperature readings when using a probe. These 5mL bottles hold tiny glass beads for easy stabilization.
A common use for the glass beads like Dickson's is to stabilize a temperature reading in a refrigerator that is opened and closed often. The air temperature in the refrigerator (or any space) may change faster than the temperature of the material you are monitoring and the glass bead bottles may better represent the true temperature of the monitored materials.
NOTE: Bottle shape may vary.
