The MS5 Coverslip Microscope Stage Chamber (Submerged) has been designed for use on microscope stages to view glass cover slips containing cultured cells. Cover slips smaller than 25mm with cell cultures are placed directly on top of a fixed glass cover slip glass at the base of the MS5. The chamber can be used with inverted microscope stages but the glass cover slip at the base of MS5 will add 200µm to the existing cultured cover slip thickness.
