The 24 well plate features a raised, clear polystyrene cover and two finger hold positions for manual or robotic manipulation. The clarified polypropylene material is resistant to most organic solvents and is also compatible with popular salts, buffers, and polymers used for crystallization. Being resistant to a wide variety of organic solvents, the Polypropylene VDX Plate can be used for hanging drop vapor diffusion or sitting drop vapor diffusion for small molecule or biological macromolecule samples in the presence of organic solvents such as acetone, benzene, acetonitrile, and other organics which are not compatible with plates made from polystyrene.
Clarified polypropylene is less permeable to water vapor.
Therefore, during long crystallization experiments, the Clarified Polypropylene VDX Plate is less sensitive to evaporation than plates made from polystyrene. The Polypropylene VDX Plate is a stackable, clarified polypropylene 24 well plate with a raised polystyrene cover. Raised, wide rings around each reservoir minimize cross contamination and allow each reservoir to be sealed with a 22 mm diameter circle or square cover slide. Glass or plastic cover slides can be sealed over the reservoir using vacuum grease or immersion oil. The raised cover protects glass cover slides from being crushed or moved during plate stacking.
