The MicroAquarium is a 2 x 3 inch, glass water cell supporting a column of water ca. 2mm thick while upright or laid flat.  Water and organisms are added via the opening across the top.  The base serves as a brace for hand lens use.  Removed from the base and placed upon a microscope stage, many microscopic details of living microcosms are easily viewed.

The MicroAquarium may be ordered from Carolina Biological Supply Company.
