Below are some FAQ’s for our New Premium Horizontal PRF Centrifuge package, which provides the latest cutting-edge technology for the PRF protocol. Instructions for the Horizontal PRF Centrifuge can be found here: Horizontal Centrifuge PRF Instructions
Q: What is the difference between your Premium Horizontal Centrifuge for PRF and the Classic Centrifuge for PRF?
A: There are several differences between our Premium Horizontal Centrifuge package and our Classic Centrifuge for PRF.
- Horizontal Centrifugation: The most important difference is that the Premium package uses a centrifuge that works on horizontal centrifugation. The Classic Centrifuge uses fixed-angle centrifugation. Recent research suggests that horizontal centrifugation for Platelet-rich fibrin (PRF) provides benefits over the classical fixed-angle centrifugation. (see the next question)
- Programmed & Custom Settings: Additionally, our Premium Centrifuge works via pre-programmed settings, as opposed to our Classic Centrifuge which is a manual machine (i.e. you need to turn the knob to get the proper setting). Our Premium Centrifuge comes pre-set with 2 PRF settings, and there are up to 8 other settings you can program on your own, based on your preferred PRF spin cycle.
- Improved Safety: Our Premium Centrifuge also comes equipped with LED monitoring and several additional safety measures, including a shatterproof lid which can only be opened when the centrifuge’s rotor is stopped, even if the unit loses power.
- Built in the USA: Finally, our Premium Centrifuge is designed, built, and supported in the USA. This allows us to provide better service, including a lifetime warranty on the centrifuge rotor.
A: Fixed angle centrifugation has been the standard protocol for PRF preparation for many years. However, recent research suggests that horizontal centrifugation may provide better results. It should be noted that outside of PRF, many large labs also now incorporate horizontal centrifugation for various applications, due to the horizontal rotors better separation ability. Horizontal centrifugation was the subject of 2 recent studies, by Miron et al. and Lourenço ES et al. 1,2
Miron et al. concluded that:
“Horizontal centrifugation produced a significant increase in both the number and concentration of platelets and leukocytes (up to 3.5× higher for either solid/liquid PRF), when compared to either fixed or angled centrifuge.” 2
As for the theory behind horizontal centrifugation, Miron et al., explains:
Two advantages are noted utilizing horizontal centrifugation. First, a completely horizontal tube produced from a swing-out bucket allows for the greatest differential between the minimum and maximum radius found within a centrifugation tube. This allows for a greater ability to separate cell layers based on disparities between the RCF-min and RCF-max produced within a tube. Secondly, a fixed-angle centrifuge results in more trauma to cells. Since centrifugation typically pushes cells outward and downward, cell layer separation is always observed in an angulated fashion using fixed-angle centrifuges…Furthermore, during the centrifugation process, cells are pushed toward the outer wall and are then typically migrate either up or down the centrifugation tube based on density. It is hypothesized that larger cells (such as red blood cells) entrap smaller cells such as platelets during the centrifugation process and drag them downward along the back centrifugation wall into the red blood cell layer as a result of cell accumulation against the back wall. In contrast, PRF produced via horizontal separation allows the direct flow through of cells. Therefore, horizontal centrifugation allows cells to migrate freely throughout the blood layers. This allows for better separation of cell types (along with the greater differentiation in RCF values between RCF-min and RCF-max) resulting in a higher final concentrations of desired cells (platelets and leukocytes) within the appropriate final blood layers. Furthermore, cells are less likely to suffer potential damage along the back wall of centrifugation tubes produced using high g-forces (~200–700g forces) following fixed-angle centrifugation. 2

A: Our Horizon 6 Flex Premium Horizontal Centrifuge comes preset with 2 PRF Protocol Settings based on the Horizontal protocols:
Solid PRF (the classic PRF Membranes and Plugs, which are referenced in the literature for the fixed-angle maches as A-PRF or L-PRF, depending on the centrifuge used) . The Solid PRF Setting is set at 2,300 RPM for 8 Minutes. This is approximately equivalent to 750 RCF (i.e. G-Force, see details below) on this machine. IMPORTANT: Please consult the instruction for the latest settings for Solid PRF based on the type of tube that is used.
Liquid PRF (otherwise known as iPRF, or injectable PRF). The Liquid PRF Setting is set at 1,200 RPM for 8 Minutes. This is approximately equivalent to 200 RCF (i.e. G-Force, see details below) on this machine.
Custom Settings The great thing about our Horizontal Centrifuge is that you can simulate any PRF protocol you want with our Horizontal Centrifuge, including new PRF protocols that maybe developed in the future, by simply adding your own custom setting. There are up to 8 additional custom settings you can use for your own PRF protocols. So for example, it is well known that due to inherent biological differences, and other factors, it is possible that for some patients 2,300 RPM for 8 minutes will not be sufficient for the PRF Membrane. If that is the case for a specific patient, you can always create a new custom setting on the machine to spin 2,300 RPM for additional 4 or 6 minutes. That way when the first spin is done, you can quickly spin it some more, if need be.
RCF and G-Force If you want to use another protocol, you should find out what particular centrifuge they are using for a particular protocol, and what RPM/time they have used, as well as the G-Force (defined as RCFmax) . With this Centrifuge, you can create PRF as described in any protocol by properly setting the RPM/time which would correspond to the proper RCF.
RCF (RCF max) describes the amount of accelerative force applied to a sample in a centrifuge. As RCF is a function of the RPM and radius of the centrifuge. PRF protocol results derived from using centrifuges with different radii are not comparable, and the RPM may need to be adjusted to achieve a similar RCF on a different centrifuge. However, different PRF protocols can be replicated assuming you get the correct information about the protocol and the machine used.
There is a simple online calculator to figure out the equation for RCF (we assume RCFmax is used, which is the international standard of measurement). The radius on the Horizontal Centrifuge is approximately 127mm.
A: The 3rd setting on the Horizontal PRF Centrifuge is simply a sample custom setting that you can use. It is preset to 2,300 RPM for 4 or 6 minutes (depending the machine). This setting is simply an additional spin time for Solid PRf. Due to inherent biological differences, and other factors, it is possible that for some patients 2,300 RPM for 8 minutes will not be sufficient for the PRF Membrane. If that is the case for a specific patient, you can always use the 3rd setting, or create your own custom setting on the machine to spin 2,300 RPM for additional 4 or 6 minutes. That way when the first spin is done, you can quickly start the centrifuge again.

A: Drucker Diagnostics recommends the centrifuge be calibrated every 2 years or 5,000 cycles. The unit can be calibrated by using a stop watch to confirm / calibrate the time, and a tachometer to check the speed. If you would like to send it to the manufacturer to be calibrated there is a $50 charge plus any shipping charges.
A: ONLY isopropyl alcohol, soap and water, or a 10% (5,500 PPM) bleach solution should be used for cleaning and disinfection of the centrifuge and accessories. All surfaces must be dried immediately after cleaning and disinfecting.
A: TBQ Germicidal products should not be used as they will cause damage to the centrifuge and void the warranty. The use of fully/partially halogenated hydrocarbons, ketones, esters, ethers, benzyls, ethyl benzenes, and all other chemicals not prescribed by Drucker Diagnostics should not be used as they may cause damage to the rotor chamber, rotor, tube holders, accessories, and centrifuge exterior. If this occurs the warranty will be voided.
