🔄 The Impact of Rotation Speed on Layer Formation

In this part, the focus is on how rotation speed affects the layering and separation of different particles in a test tube. It describes the process of rotating the test tube multiple times at different speeds, with each phase bringing different particles to settle. The paragraph stresses that increasing the rotation speed reveals specific layers and structures, making it a crucial factor in determining particle behavior during certification.

⚙️ Adjusting Speed and Visualizing Particle Layers

This paragraph discusses the procedural aspect of increasing the speed during various phases of test tube rotation. The emphasis is placed on visualizing the effects of rotation, noting that each speed increment causes different particles to settle at distinct layers. This method helps in better understanding how particles behave under varying conditions of rotation, which is essential for accurate certification results.

🌪️ Difficulties in Using Differential Certification Processes

Here, the focus is on the challenges and complexities involved in using differential certification techniques. It contrasts these processes with simpler methods, highlighting the difficulties in adjusting rotation speeds and visualizing the layers formed during testing. The paragraph also notes the importance of accurately assessing the sedimentation of particles at different speeds, which requires precise control and observation.
