Our coverslip mini-rack is a miniature support designed to vertically hold eight standard round or square coverslips. The mini-rack fits easily into a standard 50 mL beaker and can accommodate a small stir bar beneath the rack. Use of the mini-rack eliminates the necessity for repeatedly moving coverslips between solutions with forceps. The mini-rack is handy for sequential wash steps where thorough dilution and removal of material from the coverslips is critical. The mini-rack is low-binding, withstands strong acids and bases, is not damaged by heat and may be sterilized by a variety of methods such as autoclaving, organic solvent treatment or ethylene oxide exposure. The mini-rack is easily disassembled for cleaning and storage.
