This convenient holder clips onto the edge of a beaker or other vessel and holds a thermometer vertically near the side of the container for safe, easy reading.  The thermometer is held in place by small "fingers" that will expand to hold thermometers ranging from 3.2mm (1/8") to 11mm (7/16") in diameter.  Made from polypropylene, it withstands temperatures up to 121°C (250°F).  3 per bag.
