Observe the color and state of matter for 14 different substances. Test liquids for the presence of odor and observe the texture of solids. Test the acidity or alkalinity of liquids. Test the solubility of solids in alcohol and water. All materials included except: water, stirring rod, graduated cylinder, balance, hand lens (optional), safety glasses, test tubes or depression plate for solubility test. Designed for 24 students in groups of 4. Grades 8-11.
Easy one hand operation. Rotation of the thumbwheel draws or dispenses the liquid with precision and ease. By depressing the side lever the entire contents can be dispensed rapidly. Accepts glass and plastic pipettes. Color coded for sizes.
