This evaluation compares a freezer model that utilizes inner door gaskets to seal the space between the doors to a freezer model that utilizes unsealed inner doors. The impact of door openings on cabinet temperature in the closed compartments was tested for each model to understand how inner door gaskets help safeguard stored samples. **Download the white paper for the data and results.** Have further questions about Ultra-Low freezers?
