The running time, the speed, the relative centrifugal force (RCF), the centrifuging radius, the run-up and run-down parameters as well as the temperature (for centrifuges with cooling only) can all be changed while the centrifuge is running.

Hettich centrifuges are designed to spin a variety of centrifuge tubes and accessories. Particular attention should be used when spinning glass tubes and containers to avoid breakage within the centrifuge's main chamber.

Some units can weigh as much as 350 lbs when fully loaded with the rotor, buckets, adapters and media. Over time this can cause an unsecured table or unsteady work surface to become weak and in turn become a safety hazard in your lab. To avoid any issues, please make sure your unit is installed on a bench or work surface that can support the weight of your centrifuge and any other equipment you have on the same surface. Typically most lab benches in hospitals and research facilities can support the product just fine.

Predictive Maintenance: Life Cycle Counts/Maximum Cycles

Like most mechanical devices, such as a car or truck, centrifuges follow a maintenace program and part replacement schedule base on maximum cycle counts. Although this can take many years, eventually the materials used in your rotor, buckets, and centrifuges will reach the end of their useful life. By performing mechanical stress tests, we have determined the maximum amount of cycles our products should undergo before being retired.

For centrifugation safety and maximum results, the rotors and buckets may only be loaded symmetrically with all containers distributed evenly on all rotor positions. For authorized combinations, see the section "Rotors and Accessories" and "Loading the Rotor" in the Product Manual supplied with the centrifuge.
