Main Features

Ultimate Sample Protection

The Dual Cooling System offers protection by using two independent refrigeration systems. If one of the compressors partially fails, the other can continue to maintain the temperature of the freezer in the -70°C range. Learn more about the unparalleled Dual Cooling System.

Efficient Sample Storage

Designed intuitively to maximize storage space, the cabinet design creates more capacity for samples allowing more room for productivity and utilization. In addition, with an enhanced insulation performance, the cabinet keeps heat out and maintains a cooler environment at reliable uniform temperatures.

Ease of Use

With just a touch, the LCD touch panel is a smart interface that will help to put more focus on productivity through its various built-in functions. In addition, to improve the accessibility of constantly maneuvering samples in and out, the door handle is crafted with form and function in mind, providing ease when accessing samples on our upright models.
