for 115 V connection: 5301 036.002
When is it possible to open the lid of the Concentrator plus?
When the device is switched on, the lid can be opened as long as the control lamp Lid lights up.
How do I open the lid of the Concentrator plus in case of a power failure?
In the event of power failure, the ventilation valve will automatically open and the chamber will aerate to atmospheric pressure before the rotor stops spinning. Locate the pinhole on the right side of the housing, near the top rear corner. Insert a paper clip and the lid will open.
Is the solenoid valve for the control of an external pump with the basic device chemical resistant?
The solenoid valve for control of an external pump is resistant against water and alcohols.
Can the new coated lid be used with the existing Concentrator Plus?
Yes, the new lid is fully backward compatible.
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 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. Ypur local contact would be pleased to answer any further questions concerning tube dimensions.
What is the order number for the polypropylene lid of the rotor F-45-12-11?
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.
How did you manage to make the device so quiet?
The Centrifuge 5418 has an inner centrifuge lid which reduces the noise emission to a low level.
Which material is the inner centrifuge lid made of?
The inner lid of the Centrifuge 5418 is made of high-quality V2A stainless steel.
Can the Centrifuge 5418/ 5418 R be opened in case of a power failure?
Yes, the device has an emergency lid release. Before opening the centrifuge, pull the power plug and wait until the rotor stops spinning. The centrifuge 5418 has an emergency lid release via a cord that is located on the underside of the device in the base plate. Remove the white plastic cap and pull the cord downwards. The centrifuge 5418 R has an emergency lid release behind a plastic cover on the right side of the device. Rotate the plastic cover counterclockwise and remove it. Enter the centrifuge rotor key into the hexagonal opening at rear until some resistance can be felt. Slightly press and turn the rotor key counterclockwise.
How can the Centrifuge 5418/5418R be cleaned?
The Centrifuge 5418/5418 R can be cleaned with neutral detergents. For disinfection, we recommend alcohol or alcoholic disinfectants. Make sure that the relevant legal requirements and directives are observed when choosing the disinfection method. A detailed description can be found in the operating manual, which can be downloaded from our website.
What is the minimum selectable rotational speed of the Centrifuge 5418/5418 R?
The minimum selectable speed is 100 rpm. This is equivalent to an rcf of approx. 1 x g.
In which increments can the rotational speed/g-force be adjusted?
The rotational speed can be adjusted in increments of 100 rpm, the g-force (rcf) can be adjusted in increments of 100 x g.
In which increments can the time be adjusted?
In the centrifuge 5418, for a run time up to 10 min the increments are 0.5 min steps, after that it is set in increments of 1 min up to 9:59 h. The function for continuous run mode can be found above 9:59 h and below 0.5 min The symbol "oo" is displayed to indicate the continuous run. In the centrifuge 5418 R, for a run time up to 10 min the increments are 0.5 min steps, after that it is set in increments of 1 min up to 99 min. The function for continuous run mode can be found above 99 min and below 0.5 min. The symbol "oo" is displayed to indicate the continuous run.
My Centrifuge 5418 displays "EP". What does that mean?
"EP" is displayed when the automatic standby function is active. It is not an error code. 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 or knob or closing the centrifuge lid, the centrifuge is re-activated and ready to use. The letters "EP" were chosen because a lot of Eppendorf products already have this prefix in their name.
Can the fixed-angle rotor FA-45-18-11 be operated without a rotor lid?
The fixed-angle rotor FA-45-18-11 can be used with or without rotor lid. With rotor lid the centrifugation is aerosol-tight and the Centrifuge 5418/5418 R is even quieter. The aerosol-tight centrifugation can only be carried out with the rotor lid. Especially when working with pathogenic microorganisms, we recommend the usage of the aerosol-tight lid. When centrifuging filter devices like spin columns or other comparable tubes, the aerosol-tight rotor lid must be used in any case. This protects the centrifuge from damage – e. g. by torn-off tube lids.
Which material is the fixed-angle rotor for tubes made of?
The fixed-angle rotor is made of massive, anodized aluminum. This material is durable and has got a good chemical resistance. The rotor lid is made of the same material.
Can the sealing of the aerosol-tight rotor FA-45-18-11 be exchanged?
The sealing of the aerosol-tight rotor FA-45-18-11 can very easily be exchanged. A detailed description with illustrations can be found in the operating manual, which can be downloaded from our website.
