No-Roll Triangles For Thermometers, 25 Pack, Pack of 25

The No-Roll Triangles for Thermometers by United Scientific come 25 to a pack and clip onto glass thermometer stems so the thermometers stay put instead of rolling off the bench. They are designed for United Scientific's 12-inch red-liquid student thermometers. Science teachers and lab managers use them to restock classroom thermometer sets and cut down on breakage during student experiments.
