Deluxe Osmometer
Ideal for rapid and sequential demonstrations of osmotic pressure. A complete bag of thin, selectively permeable animal membrane is secured to a Y-shaped, 5-mm glass tube mounted on a 2 - 12" plastic board along side an accurate millimeter scale. Includes a metal support stand, hardware for hanging the osmometer, a squeeze-type bottle for filling the membrane bag, a Plexiglas reservoir, and instruction booklet.
