...plus instrument burnout protection...
how do the beads convey burnout protection?
how is it different from sand (re: burnout protection)?
Say someone left your water bath on overnight...the water would evaporate and your heating element would burnout- costing you several hundred dollars (sometimes thousands) to replace. On the other hand, same situation but instead of water you have the thermo-metallic Bath Beads by LabArmor beads which act as a heat sink to absorb and dissipate the heat...whereby lowering the temp of the heating element...preventing it from a burnout.
wouldn't sand offer the same protection?

Im sure sand would offer a degree of protection. However, I would consider sand an inferior heat sink. If you have ever taken a engineering course over thermal conductivity you will learn everything acts as a heat sink and an insulator. But all dense materials are not equal effective. A good heat sink material is something that absorbs heat and releases it quickly. Sand has a much lower thermal conductivity compared to the higher thermal conductivity of the metallic properties of the LabArmor Bath Bead, whereby making it the superior heat sink.

You could always buy a bath with an over-temperature cutout, ours work pretty well.

You could, but buying LabArmor bath beads would be considerably less expensive than buying all new baths with temp cutouts. Saving money is good.

Our baths are 15 years old and still working fine with temperature cutouts.

That is great, but being a heat sink is just a side show the main attraction of Lab Armor bath beads. The main point is that the beads are more efficient, less messy, and eliminate contamination risk of samples when compared to a traditional water bath.
