-86°C ULT Freezer - Self-Cascade Ultra Low Freezer - 58 to 838 L - Wide Voltage

The Master Science Self-Cascade ULT Freezer keeps samples between -40 and -86 °C using a self-cascade refrigeration system with HC refrigerant. It is available in seven sizes, from a compact 58 L unit to an 838 L upright cabinet, to fit both small labs and biobanks.

The freezer runs on supply voltages from 187 to 242 V, which suits sites with unstable power, and works in rooms from 10 to 32 °C.
