The CL-F86 protects irreplaceable samples at −86 °C behind five inches of vacuum-panel insulation and a cascade refrigeration system tuned for steady state, not spec-sheet sprints. Door openings recover quickly, and the inner doors hold each shelf’s climate while you work in another.
Temperature logs continuously to internal memory with alarm history; contacts for building monitoring come standard. In a power failure the cabinet holds safe temperature for hours — and says exactly how long it held when power returns.
Every freezer is temperature-mapped before dispatch, with the report included.
