The osmosis apparatus was designed for a visual demonstration of the process of osmotic pressure. The passage of water molecules through a semi-flowing membrane. It is ideal for study laboratories, schools and universities where chemistry, biology or physics are studied.The kit includes an osmometer with a glass bell, capillary tube, a semi-transmitter membrane and a borocrystalline glass backpack (600 ml). With its help, students can clearly monitor how water passes through the membrane and how osmotic pressure is created.
