-86°C Chest ULT Freezer 105 L and 485 L, Ultra Low Temperature Lab Freezer, -40 to -86°C

The Master Science -86°C Chest ULT Freezer stores samples at -40 to -86°C in a top-opening chest cabinet. It comes in two sizes: 105 L, holding up to 34 two-inch boxes (3400 x 2 mL samples) with optional racks, and 485 L, holding up to 300 boxes (30000 x 2 mL samples).

An optimised single-stage auto-cascade refrigeration system cools quickly and saves energy, while a PT100 sensor and microprocessor control hold the set temperature. The chamber and inner door are 304 stainless steel, surrounded by 100 mm of insulation.
