Density Gradient Centrifugation Diagram - Lab Technique Explained #239369 (License: Personal Use)

This schematic illustrates density gradient centrifugation, where a sample is layered over a pre-formed gradient (e.g., sucrose or cesium chloride) and spun at high speed. During centrifugation, particles migrate until they reach a zone matching their buoyant density, forming visible bands-here shown as red wavy layers separated by black horizontal lines representing discrete density interfaces. The open lid indicates sample loading prior to centrifugation.

Used in educational content, lab protocol guides, and molecular biology textbooks to explain separation techniques for nucleic acids, proteins, or organelles; matches user intent for learning or troubleshooting centrifugation workflows.
