There are two significant power consuming steps during centrifugation: the acceleration of the rotor as well as chamber temperature management. Cooling, performed by a compressor system, is mandatory for many high-value samples. A weak cooling system does save energy but you may risk your samples due to insufficient temperature control, ending up in a potential repetition of the experiment.
A reliable centrifuge should last for many years. The longevity of equipment is an essential aspect in the sustainability calculation for lab instruments. High quality parts and robust design enable years of trouble free usage in the lab.
Intuitive handling, low noise levels, low loading heights, or light rotors are further ergonomic building blocks to generate a sustainable centrifuge.
Refrigerated or cooled centrifuges are based on a compressor and cooling liquids to keep the required temperature within the rotor and your samples. Based on an European Union regulation (EU_517/2014), classic cooling liquids like R134a need to be replaced in a midterm perspective to counteract global warming. This is (status quo) limited to new equipment. Existing centrifuges can be continuously used without any limitations.
Still, all major centrifuge suppliers spend R&D capacities on green, future-proof cooling liquids. Due to the high kinetic energy of centrifuges and related strict safety regulations for these instruments, the usage of burnable cooling agents like propane or ethane (which are common standard for ULT freezers) requires a substantial increase in research efforts.
Eppendorf now offers Centrifuge 5427 R with hydrocarbon cooling – the first centrifuge in our portfolio with a natural refrigerant – to protect your samples, and the planet.
However, this versatile microcentrifuge does not only support you on your way to a greener lab. It is the perfect device for labs with a multiplicity of different molecular biology applications or in need of high-throughput solutions for 1.5 – 2 mL tubes – all combined in a microcentrifuge with the highest sample/footprint-ratio within the Eppendorf microcentrifuge range.
