How do I get them out, now?
Power failures, caused by the power plant, the main power line, or your local fuses in the lab, result in shut-down instruments and locked centrifuges. Especially when spinning temperature-critical samples of high value, the centrifuge lid needs to be opened as quickly as possible to avoid sample damage. Most centrifuges have emergency opening functions. When hidden at the back you need at least two strong colleagues to turn the centrifuge by 90° to gain access to the mechanism.
The emergency opening function should be easy to reach: at the front area or the front side area of the centrifuge. Pull a cord or use the rotor key to open the lid and save your samples.
