Our collection of flexible gel drying systems accommodate multiple gel types and allow optimization of drying conditions to minimize gel cracking. Each unit is light and robust, and functions with slab, gradient, 2D, immunodiffusion, immunoelectrophoretic, and enzyme activity gels. Gels can be air-dried or through the application of heat for heavier gels. Color of stains for proteins, glycoproteins, nucleic acids, and colorized enzymatic products remains stable for years.
