Microcentrifuge Tube with Liquid Sample

This image presents a common laboratory item: an open microcentrifuge tube. The tube contains a liquid sample that clearly shows two distinct layers – a lighter, possibly pelleted, substance at the very bottom and a light blue liquid occupying the space above it. A subtle horizontal line is also visible within the blue liquid, potentially marking a volume or indicating further stratification within that layer. This setup is often seen in processes like centrifugation or various sample preparation steps in scientific research.
