Review on Liquid Thermometer Non Roll Fitting B61401 5300 by Andrew Dickens

For glass laboratory thermometers that do not have a ring at the top. This will prevent it from rolling away and the loop can be used for holding. There are 25 pieces in a pack. They are purple in color (obviously the only color available) and are made of soft vinyl rubber that holds up well. HB also makes a triangular style, which is a simple ring with no loop at the top. Here at Amazon I've seen the price fluctuate from a high of over $20 (half crazy) to a low of $5.27 (good). If it saves at least one thermometer from rolling off the table and breaking, then it's worth it.
