Powerful and easy-to-use MiniSpin® and MiniSpin plus microcentrifuges are small enough so that each workstation can be equipped with a “personal” centrifuge for a wide range of molecular biology separations and quick spins. Two models are available to meet your performance requirements.
- 12 x 1.5/2.0 mL capacity rotor
- Speed up to 12,100 x g for MiniSpin and 14,100 x g (14,500 rpm) for MiniSpin plus, sufficient for molecular applications
- Extremely compact footprint ideal for training labs or individual work stations
- Remarkably quiet operation
- Extremely low profile for easiest rotor loading and unloading
- Soft-touch lid closure for ergonomic lid locking
- Lid opens automatically at the end of the run to prevent sample warming and to allow easy access to samples
- Optimized air flow minimizes sample warming—protects temperature-sensitive samples
- Fast acceleration and braking times save time
- Digital display for reproducible setting of time and speed
- ShortSpin button for fast quick spins
- Rotor, inner centrifuge lid and lid latch are made of metal for maximum operational safety and compliance to IEC 1010-2-020 safety regulations
- 2-year warranty

Can the MiniSpin/ MiniSpin plus be operated in a cooling room?The centrifuges can be operated in ambient conditions of 10 - 40 °C. The permitted relative humidity must not exceed 75 %. When transferring the centrifuge from a colder into a warmer environment, the centrifuge must either be allowed to run warm for a half an hour in the cooling room or it must be allowed to warm up in the warmer environment for at least 3 hours. During this time, it must not be connected to a power source. In order to avoid damage from condensation, centrifuges should generally not be submitted to frequent temperature changes.
Is the MiniSpin/ MiniSpin plus equipped with an imbalance switch-off function?No. These centrifuges have been extensively tested and do not need an imbalance switch-off function.
How high is the noise level of the MiniSpin/ MiniSpin plus?The measured noise level is less than 49 dB(A) / 52 dB(A) (MiniSpin / MiniSpin plus). Both centrifuges are therefore distinguished by an extremely quiet run.
Are motor brushes required for the drive unit of the MiniSpin/MiniSpin plus?No, both centrifuges are distinguished by a maintenance-free (inductive) drive unit.
"Err 8" appears on the display. What does this mean?The error code "Err 8" appears on the display of the centrifuge if the rotor is not screwed tight enough. Therefore check the position of the rotor.
What does "Err 5" mean and how can I restart the MiniSpin/ MiniSpin plus?The error code "Err 5" appears on the display of the centrifuge if the lid latch is defective. If this error occurs during centrifugation, the device must remain switched on without being operated for 8 minutes. After that, the centrifuge lid can be opened by pressing the "open" button.
What are the maximum values for relative centrifugal force (RCF, g-force) or for the rotational speed (rpm) that can be set for the MiniSpin/ MiniSpin plus?The maximum rotational speed that can be set for the MiniSpin is 13,400 rpm, equal to 12,100 x g. The maximum rotational speed for the MiniSpin plus is 14,500 rpm, equal to 14,100 x g.
What are the minimum values for the relative centrifugal force (RCF, g-force) or for the rotational speed (rpm) that can be set for the MiniSpin or the MiniSpin plus?The lowest rotational speed that can be set for both centrifuges is 800 rpm, equal to approx. 50 x g. In contrast to the MiniSpin, the MiniSpin plus can be switched back and forth between rcf and rpm by simultaneously pressing the "speed" arrow keys.
What is the max. radius for 1.5 and 2.0 mL micro test tubes in the standard rotor of the MiniSpin/ MiniSpin plus?The max. radius for 1.5 mL tubes in the rotor F-45-12-11 of the MiniSpin/ MiniSpin plus is 5.9 cm. For 2.0 mL tubes it is 6.1 cm.
What distinguishes the silver-colored aluminum rotor F-45-12-11 from the black-colored aluminum rotor F-45-12-11 of the MiniSpin/ MiniSpin plus?The silver rotor F-45-12-11 may only be used in the MiniSpin as it is only permitted for the lower maximum rotational speed of this centrifuge. However, this rotor can no longer be ordered. Instead, like the MiniSpin plus, the MiniSpin is now supplied with the black rotor F-45-12-11.
Can filter inserts that project approx. 1 cm out of the tubes be centrifuged in the MiniSpin/ MiniSpin plus?These so-called spin columns can be used when the rotor lid used is made of stainless steel. This application is not possible with the older polypropylene lid. Almost all spin columns from a variety of purification kits can be used with the stainless steel lid. The Application Hotline (firstname.lastname@example.org) would be pleased to answer any further questions concerning tube dimensions.
What is the order number is the polypropylene lid of the rotor F-45-12-11 available?The polypropylene lid for the rotor F-45-12-11 of the MiniSpin/ MiniSpin plus can no longer be ordered. In its place, a stainless steel lid distinguished by a high degree of chemical resistance and enabling the use of particularly long and previously unusable spin columns is now available under the order number 5452 702.000.
