With the resistant refrigerator lab ULT-728 from CARLO ERBA Reagents GmbH nothing can go wrong in your laboratory! Many different samples, medicines as well as vaccines can be professionally stored there.

Safe temperature control

A temperature control you can rely on. The integrated electronic system supports you here. A bonus for safety: the key holder that is also provided protects the settings from tampering. Sensitive materials such as pharmaceuticals, medicines or biologicals can therefore be stored under optimum conditions thanks to this regular temperature distribution and the convection cooling.

The contents are also adequately protected from sub-zero temperatures. Everything in view, thanks to the digital display! And you can make any other temperature changes individually via the keypad. This appliance also has a minimum and maximum temperature memory.

Comfort and efficiency with no-frost technology

Need a refrigerator that takes some of the hassle out of defrosting? Our team of experts will be happy to advise you on one of our wide range of refrigeration systems, without obligation, to find the right offer for you.

Sufficient storage space for samples, drugs & medicines

Adjustable drawers for more space: Design the storage space according to your wishes! The stainless steel cladding completes the interior of the blood plasma freezer.

Efficient energy consumption

Some refrigerators of the series of the brand manufacturer CARLO ERBA Reagents GmbH come with a self-closing door with a practical intermediate lid, which can also be locked. This way, you can make sure that all contents are kept in the best possible place. Thanks to an energy-efficient insulation made of solid, valuable, pressure-foamed and sustainable material, the cooling system achieves a reduction in power consumption.

Sophisticated safety

In case of temperature deviations or other faults, you will be immediately informed by a visual as well as an acoustic warning signal. In the event of an unauthorised door opening, an alarm will also sound after one minute. The monitoring unit remains in operation for approx. 30 hours by means of a rechargeable battery – so you will also be alerted by the optical and acoustic warning signal in the event of a power failure.
