FAQ

It is not allowed to centrifuge explosive and inflammable materials in MPW MED. INSTRUMENTS centrifuges. Toxic or infectious materials can be centrifuging only in closed, sealed bucket. Detailed recommendations contained in the User Manual (section: Safety notes).

Sterilization of MPW MED. INSTRUMENTS can be carried out by means of the measures listed in the User Manual for the centrifuge (chapter: Maintenance/Sterilization). The use of other resources from the specified may cause reduction of durability or change the color of the product. For any information on the impact of the measure on the elements of MPW made of steel, aluminum and plastic (including elements covered with galvanic or lacquered coatings), and of the effectiveness of the sterilization one should inquire the supplier means X.

The centrifuge detected an incorrectly balanced rotor. Make sure that the rotor is at rest, open the cover and check that the test-tubes used are of the same type and are evenly filled (they have the same weight). The centrifuged elements should be placed symmetrically. Detailed rules of placing the tubes in the rotor can be found in the centrifuge operating manual. Restart centrifuging after making sure that the rotor, containers and inserts are properly fixed and the cover is closed. If the problem persists, contact the service.

In the case of a message about motor overheating, switch off the power supply to the centrifuge and contact the service.

Glass particles will damage the external coating of the rotors and containers, which will lead to corrosion of these elements and prevent their proper operation. The presence of glass particles in the holes of the inserts, containers and rotors may cause the subsequent tubes to crack, and contamination of the rotor pins may cause the containers to swing out incorrectly, and as a consequence, a message is displayed to inform about the unbalance detection.

Make sure that the rotor is at rest, and then open the cover with the COVER button. Carefully remove all glass fragments of the tubes from the centrifuge chamber with a tool such as a vacuum cleaner. To remove the finest particles and glass dust, cover 1/3 of the centrifuging chamber surface with grease, e.g. technical petroleum jelly. Close the cover and start centrifuging at 2,000 rpm for a few minutes. Use a cloth to remove the grease and the glass dust accumulated in it. If necessary, perform this operation again.

If there is a spillage of biologically or chemically aggressive substances in the chamber, neutralize them with care and in a way that does not endanger health or life. If you suspect that the centrifuged substances or agents planned to neutralize them may be aggressive to the centrifuge components, please contact the service.

Use the configurator available at https://mpw.pl/en/configurator, which allows you to define your needs such as: type and number of tubes in one centrifuge, required RCF or RPM, centrifuge angle, temperature control and find the centrifuge and the equipment that fits your requirements. We also invite you to contact the Sales Department directly (contact details can be found at https://mpw.pl/en/contact/contact-details).

In the angular rotor the tubes are centrifuged at a constant angle, e.g. 45 degrees. In the horizontal rotor, however, during centrifugation, under the influence of centrifugal force, the containers and test-tubes swing to a horizontal position. In the angular rotor, the individual fractions are arranged at an angle, e.g. 45 degrees, and in the horizontal rotor parallel to the bottom of the vessel.

We have a wide range of rotors to suit different applications. You can find a detailed offer at https://mpw.pl/en/offer. We also provide support in case of requests for tailor-made solutions. In such a case please contact the Sales Department (contact details can be found at https://mpw.pl/en/contact/contact-details).

The test-tubes used should be of the same type and evenly filled (have the same weight). The centrifuged elements should be placed symmetrically. Detailed rules of placing the tubes in the rotor can be found in the centrifuge operating manual.

RCF ( Relative Centrifugal Force) - the relative centrifugal force being a multiple of the acceleration of the earth's G, which acts on the centrifuged sample.

RPM (revolutions per minute), number of full rotor revolutions.

In order to choose the right RPM or RCF value for your needs, we encourage you to use the RPM/RCF calculator available at https://mpw.pl/en/calculator. With it you can easily determine the required RPM or RCF values depending on the centrifugation radius.

Centrifugation efficiency depends on two parameters – centrifugation radius R and centrifugation speed RPM. Using the RCF value, which includes both of these values, you do not need to make any calculations and select the centrifugation speed according to the radius available in your rotor. When selecting centrifuging parameters, it is recommended to use the RCF parameter.

This is the distance from the axis of the rotor to the point where the farthest part of the centrifuged sample is located. The centrifugation radius together with the centrifugation speed are used to determine the RCF value.

Centrifuge validation is a procedure carried out by authorized service of the manufacturer, which is to confirm correct operation of the device and meeting the safety requirements.

Validation consists in evaluating the centrifuge without dismantling it. In contrast, the centrifuge is disassembled as part of the inspection in order to assess the condition of the components most exposed to wear and to replace them if necessary. After the inspection the validation is carried out.
