Six shelves and 312 litres of net volume make the Gram BioBasic RF410 a full-height laboratory freezer for larger sample collections. The temperature can be set between −25 and −5 °C, and the cabinet operates at room temperatures of +10…+35 °C.

Gross volume 346 litres, energy use 2.06 kWh per 24 h, noise level 36.6 dBA, refrigerant R600a. The door is right-hinged and locks with two keys; the exterior is white lacquered steel.
