Equipment and Software

MicroAquarium™: is a 75 X 50 X 4mm glass chamber designed for studying small aquatic organisms with a compound or dissecting microscope.  It is made with two 75 X 50 cm microscope slide glasses sandwiched together with a 2mm space between.  It is sealed on three sides (two short and one long side) with 100% Silicone Aquarium Sealant from All-Glass Aquarium Co., Franklin, WI– www.all-glass.com. The MicroAquarium™ is stored vertically (open end up) in a plastic stand with a clear plastic cap over the opening.
