Compact disk (CD) Microfluidic platforms are being studied for medical applications such as blood tests. However, its size is bulky and electricity is needed to realize centrifuge force. In this paper, bearing-based hand spinner is designed using three-dimensional printer. This spinner does not need electricity and keeps rotating direction unlike paperfuge while it is spinning. The properties of spinner vary depending on bearing type which is positioned at the center. The type of weighting area also affects change in RPM over time. When a separation experiment is implemented, separating mixture into red ink and oil and whole blood into red blood cell and plasma are achieved properly with ceramic ball bearing.
光盘（CD）微流控平台正用于血液检测等医学应用的研究。然而，其尺寸较大，且需要电力来实现离心力。在本文中，利用三维打印机设计了基于轴承的手动旋转器。这种旋转器不需要电力，并且在旋转时与纸离心机不同，它能保持旋转方向。旋转器的特性取决于位于中心的轴承类型。配重区域的类型也会影响每分钟转速（RPM）随时间的变化。当进行分离实验时，使用陶瓷滚珠轴承能将混合物成功分离为红墨水和油，以及将全血分离为红细胞和血浆。
