Can the new rotor generation be used with older Centrifuges without retrofitting?
Can the new rotor generation be used with older Centrifuges without retrofitting?
Yes, you can use the new rotors from software version 8.4 onwards. From versionb 7.0 on a software update to version 8.4 can easily be performed by trained service technician. In case of older software versions, the complete PCB control/frequency converter must be replaced. You can see the current software version of your centrifuge briefly on the display after switching it on.
How does the Centrifuge recognize that a different rotor is in use?
How does the Centrifuge recognize that a different rotor is in use?
A new rotor automatically will be recognized as soon as it starts moving. Moving and recognition of the rotor can be performed manually by making it spin counterclockwise (roughly 200 rpm necessary), or by turning the Centrifuge on. As soon as the rotor starts spinning it will be recognized. When indicated, the Centrifuge shuts down under specification of max. speed in case the indicated max. speed of the previous rotor was higher. In this case the Centrifuge must be restarted.

Sometimes my Centrifuge 5427 R displays "EP". What does that mean?"
EP" is displayed when the automatic standby function is active. If the centrifuge remains unused for more than 15 min., the standby function is activated, indicated by "EP" on the display. By using any key, the centrifuge is re-activated and ready to use.
Can the Centrifuge 5427 R automatically recognize an installed rotor?
Can the Centrifuge 5427 R automatically recognize an installed rotor?
The Centrifuge 5427 R has an automatic rotor recognition system. A newly installed rotor is recognized at the beginning of the run. The maximum speed of each rotor is automatically limited, if necessary, to prevent over-speeding of the rotors.
What benefits do I gain from the centrifugation of my samples with the swing bucket rotor? …
What benefits do I gain from the centrifugation of my samples with the swing bucket rotor?
One advantage of centrifugation with the swing bucket rotor is the possibility of sedimenting molecules that cannot be pelletized with a fixed-angle rotor (Microgradient, e.g. blood / Ficoll).
What is the benefit of a so-called Kit rotor?
What is the benefit of a so-called Kit rotor?
When working with nucleic acid purification kits with spin columns by certain manufacturers, sometimes tube lids cannot be closed any more. This means you have to centrifuge with open tube lids. These tube lids might rip off during the stress of centrifugation and might damage the centrifuge. In order to prevent this, the kit rotor with the raised rotor rim was designed. Open tube lids, supported against the rim, will not rip off during centrifugation. Another feature of this rotor is the enlarged distance between the rotor bores. The enlarged distance between the bores offers a very convenient handling when loading / unloading the rotor. Especially when working with long spin columns (e. g. from Princeton Separations) you will need a larger distance between the bores to load the rotor fully and make use of the complete rotor capacity.
What tubes can be centrifuged with the Centrifuge 5427 R?
What tubes can be centrifuged with the Centrifuge 5427 R?
Due to the different rotors and adapters, a wide variety of tubes can be centrifuged with the

In which rotors can I centrifuge 0.5 mL micro test tubes?
In which rotors can I centrifuge 0.5 mL micro test tubes?
0.5 mL micro test tubes can be centrifuged in all rotors for 1.5/ 2.0 mL micro test tubes using an adapter.
In which rotors can I centrifuge 5 mL micro test tubes?
In which rotors can I centrifuge 5 mL micro test tubes?
Up to 16x 5 mL micro test tubes can be centrifuged in the aerosol-tight rotor FA-45-12-17.
In which rotor can I centrifuge spin columns?
In which rotor can I centrifuge spin columns?
Spin columns or small filtration columns, for example for centrifugation of DNA or RNA, can be used in all rotors for 1.5/2.0 mL micro test tubes.
In particular, however, the kit rotor F-45-24-11-Kit is specially suitable for such spin columns, as open tube lids are supported by the raised edge of this rotor type and are no longer torn off (e.g. during elution of the sample from the column into a micro test tube)
What is "Fast Temp"?
What is "Fast Temp"?
The "Fast Temp" function is a temperature control run of the Centrifuge 5427 R without samples and with a rotor and temperature-specific rotational speed in order to quickly bring the rotor chamber, incl. the rotor, buckets and adapters, to the set nominal temperature. In order that the samples can be centrifuged from the beginning on at the desired temperature, one starts this temperature control run during sample preparation by pressing the "Fast Temp" key. The display shows the current temperature and the g-force (rcf) / rotational speed (rpm) as well as "FT" as symbol for a "Fast Temp" temperature run. You can find a more detailed description in the operating instructions of the Centrifuge 5427 R.
When does the continuous cooling of the rotor chamber start?
When does the continuous cooling of the rotor chamber start?
The continuous cooling starts with each rotor standstill of the Centrifuge 5427 R in order to maintain the preselected nominal temperature of the rotor chamber not only during centrifugation. To this purpose the following prerequisites must be met:
- The centrifuge is switched on.
- The centrifuge lid is closed.
- The nominal temperature is lower than the ambient temperature.
- The centrifuge is not in standby mode.
Continuous cooling is ended by opening the centrifuge lid or by pressing any key.

Does the Centrifuge 5427 R has an energy saving function?
Does the Centrifuge 5427 R has an energy saving function?
Continuous cooling is switched off if the centrifuge is not used for longer than the preset time. The centrifuge switches to standby mode.
- Default settings: Continuous cooling ends after 8 h.
- Continuous cooling can be limited to 1h, 2h or 4 h
What is the SOFT function?
What is the SOFT function?
The SOFT function of the Centrifuge 5427 R allows slower and gentler acceleration and braking compared to the normal acceleration and braking times. As a result, delicate samples are not stressed unnecessarily. In addition, the risk of the pellets being shaken up again during braking is minimized.
