Freeze-Thaw Events: What to Document in Research

A documentation framework for recording repeated temperature transitions without assuming that one material’s stability profile applies to another.

Questions to document

  • How many freeze-thaw events occurred, and over what time period?
  • What container, solvent, concentration and temperature range were used?
  • Is there material-specific stability evidence for the storage and assay conditions?
