BDW-86L770 Ultra-Low Temperature Freezer — Maximum-Capacity 770L -86°C with 20 Racks/500 Boxes and 1800W for National Biobanks and High-Demand Clinical Research

The BDW-86L770's 770L nominal capacity and 780 × 760 × 1310 mm internal volume — the deepest in the BDW-86L Series at 760mm internal depth — accommodate 20 racks and 500 storage boxes for the largest single-unit biological material collections in the series. National biobanks housing multi-decade longitudinal cohort sample collections, pharmaceutical companies maintaining comprehensive biological reference standard libraries, and large clinical research units archiving complete trial biological sample sets use the BDW-86L770 for maximum-capacity single-unit -86°C storage.

The BDW-86L770's stainless steel interior provides the corrosion resistance and cleanability required across the maximum-capacity 780 × 760 × 1310 mm interior for sustained high-volume biobank and pharmaceutical cold storage operations — enabling thorough cleaning after biological material spills and periodic deep cleaning without surface degradation across the extended multi-year operational lifetime of a flagship -86°C freezer.

The BDW-86L770's advanced insulation system maintains -86°C against the ambient environment across the maximum-capacity cabinet — with insulation matched to the larger thermal mass and surface area of the 770L format to provide comparable energy efficiency and cold chain resilience to the smaller BDW-86L Series models during power interruptions and high-frequency access operations.

The BDW-86L770's touch screen and data recording capability provide operational management and continuous electronic temperature history for the maximum-capacity biological material collection — the most comprehensive documentation infrastructure requirement in the series where the largest collection value and the broadest regulatory documentation obligations coincide.

At 1800W — the highest in the BDW-86L Series — the BDW-86L770's refrigeration and heating systems provide the thermal capacity required to achieve and maintain -86°C across the maximum 770L cabinet volume and 490 kg total system weight. The higher power reflects the greater refrigeration demand of the larger thermal mass and the deep 760mm internal cavity that creates additional thermal challenges for the refrigeration system compared to the narrower standard models.
