Melting Point Apparatus
This apparatus makes it easy and simple to measure the melting point (250°C limit). The apparatus consists of an aluminum testing block with a slanted thermometer hole. Sprinkle material on the top of the block, insert the thermometer into the slanted 7mm hole, and heat the block from below using a Bunsen burner or other heat source to test. As soon as the material starts to melt, read the thermometer for the melting point. Support stand, support ring, Bunsen burner, and thermometer are required but not included. 50mm L x 63mm W

Ring and Ball Apparatus
This apparatus consists of 2 brass rods with insulated handles. One of the rods has a ring and the other has a ball of approximate diameter 1″ (25 mm), attached at the end. The brass ball passes through the ring when both are at room temperature, but when the ball is heated it expands and cannot pass through the ring, demonstrating the expansion and contraction of metals.

Item 3230-00
Compound Bar/Strip
Use this bar to demonstrate unequal expansion in different metals on heating. It consists of a laminated strip of 2 different metals fitted in a plastic handle. Due to differences in the coefficients of linear expansion of both metals, the laminated strip bends dramatically on heating.
• Comes with a Teacher’s Guide
• Strip is approx. 8″ (200 mm) L x 0.38″ (10 mm) W
