Hettich Upright freezer HS 2486-A

You require safe, secure storage for youvaluable samples. Tissue specimens, DNA, RNA, protein preparations and similar substances need to be stored in such a way as to ensure they are well preserved. With a constant temperature of -86°C, Hettich freezers offer the optimal environment for your sensitive samples.

Inside doors and sectional covers enable selective access, so that other stored substances remain protected. Thanks to movable shelves, the interior of the upright freezers can be orga nised flexibly and according to your specific requirements. Removable trays are easy to pull out, as their special design prevents freezing. Your samples will be stored conveniently and trouble-free in suitable racks and boxes, designed to accommodate the most varied types of tubes.

We know how important it is that your freezer operates perfectly over the long term. That`s why we manufacture our freezers using only the best materials of European origin and equip them with the most extensive range of security and control functions. Hettich freezers will guarantee optimal conditions for your samples for many years to come.

Ice can easily be wiped off the stainless steel interior surfaces.The insulation of the interior doors prevents the formation of ice.

The compressor is smaller and consumes less energy, whilst delivering the same performance. The lower heat generation and excellent insulation reduce energy costs. The cooling system heats the plastic surround of the outer door and thus elimi- nates the need for electrical door heating. The door seal remains free of ice. The two inner doors have optimal insulation to minimise any rise in tempera- ture when the outer door is opened.

Modern communication technology is used for the web-based control system. Every Hettich freezer can be assigned its own IP address on the Internet. Communication with the freezer is possible in one of 3 ways:
