Rack will hold up to 12 microscope slides with dimensions such as 75 mm x 25 mm, (3" x 1") and even 76 mm x 26 mm and with a thickness of 1.0 mm to 1.2 mm. The slides fit into individual slots for free passage and rapid drainage of staining fluids. Since they are placed vertically in the rack and not horizontally, their writing area will not be stained by the fluid, allowing their removal without the use of forceps. The lid completely covers the EasyDip™ Slide Staining Jar to minimize spill and evaporation. A handle is permanently attached to the rack for easy insertion and removal of slides without the user's fingers touching the solution.
