The QX-102 Capsules are used for imaging various wet materials and biological samples such as food, cosmetics, oils, paints, particles in solutions, adherent and non-adherent cells, and microorganisms. Materials of various consistencies such as foams, gels, creams and emulsions can be easily viewed using the QX-102 Capsule. The samples can be visualized either directly or by following appropriate contrast enhancement staining or labeling procedures. The capsule serves as a cell culture dish, specifically designed for the SEM. No coating or embedding of the sample are required, enabling electron microscopy imaging with easy sample preparation comparable to light microscopy.
