                     Best Centrifuge for 
PRP Preparation
Platelet rich plasma PRP therapy is a type of regenerative medicine that 
employs a patient’s own platelets to address medical and aesthetic concerns. 
By administering injections of their own platelet concentrate, the body’s 
natural healing mechanisms are activated. Proper preparation of PRP is crucial 
for maintaining the viability of platelets and this is typically achieved through 
the use of a PRP centrifuge.
This blog will cover the essential 
guidelines for centrifugation in PRP 
treatment. The ideal centrifugation 
method to achieve optimal platelet 
concentration depends on the type of 
PRP therapy required for the patient. To 
ensure a successful administration of the 
treatment, it is important to use the 
appropriate PRP kit for platelet activation 
and recovery. Factors such as time and 
speed of centrifugation force are also 
taken into account to attain a favorable 
platelet yield.
In this blog, we shall touch base the best practices for centrifugation 
during PRP treatment. The method used to get optimal platelet 
concentration will depend on the kind of PRP therapy the patient 
needs. Using the right PRP kit for platelet activation and platelet 
recovery is essential for the successful administration of the treatment, 
as well as factors like time and speed of centrifugation force are 
considered in getting favourable platelet yield.
Understanding the Centrifugation Process for Platelet-Rich 
Plasma
Centrifugation is a process used to separate the blood cells 
from the liquid plasma in PRP therapy. It is the initial step in 
collecting autologous platelets for the treatment injection. 
To begin, a clinician will carefully draw a blood sample from 
the patient’s arm using a syringe. An anticoagulant, such as 
sodium citrate, is added to prevent clotting of the blood 
sample after extraction.
Following blood extraction, the sample is stored in a test 
tube and subjected to rapid spinning using a centrifugation 
device. The centrifugation process causes the red and white 
blood cells to settle at the bottom of the tube, leaving the 
plasma at the top. Utilizing a PRP centrifugation machine 
streamlines this process, providing a plasma sample with a 
high concentration of platelets.
Factors that can affect the Centrifugation process
1. Selection of centrifuge model
The Neuation’s swing out rotor 
Centrifuge is a frequently used model 
for preparing platelet-rich plasma 
(PRP) because it is considered the 
best option for achieving optimal 
separation of plasma components 
based on their density. This is due to 
its swing-out (horizontal) design, 
which is superior to angled 
centrifuges in minimizing cell trauma 
and damage, resulting in higher 
quality PRP.
2. Method of spinning
There are two prevalent techniques used in 
the spinning process for PRP: single spin and 
double spin. The gel system utilizes the 
single spin technique, whereby osmosis 
generates a barrier that separates the blood 
cells and the plasma.
Conversely, the double spin technique involves 
two stages. Initially, the blood is subjected to a 
hard spin to disintegrate the RBCs, WBCs, and 
plasma. Subsequently, a second, gentler spin 
further separates the blood components, 
resulting in an elevated concentration of 
platelets.
3. Centrifuge time
Typically, centrifugation devices rotate blood 
samples for approximately 10 minutes. However, a 
recent study has demonstrated a correlation 
between the duration of centrifugation and the final 
composition of the resulting PRP sample. The study 
examined blood samples that were spun at a low 
setting for either 6 or 10 minutes. 
Samples that were centrifuged for 10 minutes 
showed higher concentrations and better platelet 
recovery compared to those processed for only 6 
minutes. These findings suggest that controlling the 
duration of centrifugation is a crucial factor that can 
affect the concentrations and platelet recovery of 
the PRP sample.
4. Speed
The centrifuge’s speed and force have a 
significant impact on the blood 
separation process. A higher centrifugal 
force applied by the device leads to 
increased rotation, resulting in improved 
separation of the platelets and blood 
cells. The speed of centrifugation is 
usually measured in revolutions per 
minute (rpm), and when it comes to 
blood samples, the standard 
centrifugation speed is 3400 rpm, unless 
otherwise indicated.
5. Temperature   
High-speed blood spinning can generate 
friction, which raises the temperature of the 
sample. This temperature increase can 
cause the concentrated platelets to enter 
the activation phase prematurely, leading to 
reduced viability and platelet aggregation. 
Recent studies suggest that reducing the 
temperature to a range of 12°C to 16°C 
during centrifugation may improve platelet 
recovery and increase their viability.
Conclusions
Despite the numerous methods available for preparing platelet-rich plasma 
(PRP), the most effective approach may not always be clear when aiming to 
facilitate tissue repair and bone growth through therapeutic use. This blog 
offers recommendations to assist in optimizing the preparation of PRP in 
clinics and labs, with the goal of enhancing the quality of treatment 
provided to patients.
