Use a Label Gun to Mark Warmed Fluids
Need an easy way to track when you need to remove solutions from the warmer cabinet? Go to an office supply store and purchase a price-marker label gun (you can find one for around $20). Store the gun (along with its instructions on how to set the date) by the warmer. As a staff member places bottles in the cabinet, he can take the gun, quickly set the expiration date, print and stick the easy-to-read and bright labels on each bottle. This cheap trick ensures that all bottles are clearly marked with the date when you need to remove them from the warmer.
