Environmentally Friendly Release Agents in Centrifuge Production

During the production of cooling centrifuges, the refrigerator rotor bowl is isolated with special foam before being attached to the exterior of the centrifuge. In the process, a release agent is needed to keep the insulating foam from sticking to the foam mold. The release agents available on the market were unsatisfactory in terms of their functionality and their environmental properties.

Cooling centrifuges are an important part of our product portfolio. During production, the refrigerator rotor bowl is isolated with special foam before being attached to the exterior of the centrifuge. This is the only way to ensure that the centrifuge's temperature can be controlled precisely to guarantee reliable research results for our customers. In the process, a release agent is needed to keep the insulating foam from sticking to the foam mold.

The release agents available on the market were unsatisfactory in terms of their functionality and their environmental properties, so our employees at Eppendorf Zentrifugen GmbH in Leipzig contacted our foam supplier and cooperated with the company to develop a completely new release agent based on water instead of organic solvents. This agent is harmless to humans and 100% biodegradable. In addition, the use of the new agent allows the insulating foam to fill the available space even more precisely than before, which increases its insulating properties.

The greatest gains from this innovation go to our customers, who now need less energy to operate a cooling centrifuge from Eppendorf. But the environment wins, too, because our centrifuge production has become environmentally friendlier.
