Freezing Microtome, and Microwave

The upper chambers are removed along with a gasket from the plastic slide the slide can be covered with a 22 X 50 mm coversUp 

A new technique uses microwaves to speed the diffusion of reagents into tissues. Microwaves can be used for ultra-rapid processing of tissue and speeding incubation times. While the theories are still not well understood, they might go something like this Microwaves cause increased vibration of polarized molecules in the tissue and this speeds the diffusion. The microwave has a cooling bath so that the tissue samples stay at room temperature during the exposure. This method is useful for
