Value flammable material storage (FMS) refrigerators

These refrigerators are designed to be used for the storage of volatiles, compounds, and solvents where a spark-free internal cabinet environment is required. Household/commercial refrigerators and freezers are not suitable; they have components in their electrical and refrigeration systems that can trigger explosions of flammable air-vapor mixtures inside the unit. Thermo Scientific flammable storage laboratory refrigerators are available from under-counter models to full-height, freestanding options.
