These stills effectively remove inorganic solids, organics, bacteria, and pyrogens, resulting in high-quality solutions for use in laboratory and general manufacturing applications. All models are constructed from inert materials that prevent any leaching of contaminants into the water. Certain models are designed specifically for inexpensive and convenient demonstrations of organic chemistry in action, conducting organic synthesis in microscale for observational purposes. All stills are ergonomically designed desktop units for use in laboratories of any size.
