These liquid-in-glass thermometers have physical and performance characteristics identical to ASTM thermometers for their referenced applications, but have not yet been reviewed and accepted by ASTM for these purposes. They use a safe blue indicating liquid that is biodegradable, nontoxic, and nonhazardous. Dark blue color is easily read against the white-backed stem.

To prevent fluid column separation, always store Non-Mercury Thermometers vertically, using a storage rack.
Thermometer Well provides protection and thermal stabilization for glass laboratory thermometers used in ovens or other exposed environments.
