3-Part Human Ear Model, 3X Enlarged, 29 Features Electricity & Magnetism_Electrostatics supporting semi-quantitative hydroperoxide and ether

supporting semi-quantitative hydroperoxide and ether peroxide monitoring in the lab

sized for finer-gauge resistance demonstrations and small-scale heating elements where the heavier gauges would over-deliver current

Twelve-slot natural wood buret rack organizes vertical buret storage and simultaneous titration setup in chemistry and analytical laboratory classrooms

sized to dust evenly over paper or around a magnet to make field lines visible during introductory magnetism work
