Sustainability for Centrifuges

Besides pipettes, centrifuges are one of the mostly used instruments in the lab. Literally all protocols and workflows require one or more steps where samples need to be centrifuged or spinned.

How can I find a sustainable centrifuge?

Energy savings
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.

Longevity
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. 

Ergonomics
Intuitive handling, low noise levels, low loading heights, or light rotors are further ergonomic building blocks to generate a sustainable centrifuge.

Cooling liquids
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.
