Online Learning Session: Dispersion Staining

McCrone Research Institute is currently offering live online microscopy presentations on the Zoom video conferencing platform.

In this week’s session, attendees will learn the basic principles of dispersion staining. McCrone Research Institute microscopy instructor Meggan King will give a short lecture, review setting up the polarized light microscope for dispersion staining, and demonstrate how to make a central-stop dispersion staining objective, which is useful for the detection and identification of small particles. All skill levels are welcome to attend.
