Free lab tools
Small tools for lab people.
Plain web pages that do one job well. They run in your browser, upload nothing, and need no account.
Nothing you type leaves your computer.
Freezer box map maker
Pick a 9x9, 10x10 or custom box, fill it with sample IDs, and print a one-page map or a blank template. Save your boxes to a file, or download a CSV.
Open the tool →Freezer failure plan and door map
List what is in each freezer, set a priority for every box, and print a large-print door map and a freezer-down sheet with contacts, the order to rescue boxes in, and a log. A planning aid, not safety advice.

These tools come from LimsRat, a sample tracker for small labs that keeps your data on your own device. The tools stand on their own: you do not need LimsRat to use them, and they never ask you to sign up for anything.
