Goldenrod Paper— Demonstration Kit
The dye used in this special goldenrod paper acts as an acid–base indicator. When the paper comes in contact with a base,
it changes from goldenrod to a dark red. Write hidden messages, splash fake blood or amaze your students with this great introduction to acids and bases. Instructions describe what bases to use and how to perform this demonstration so the paper
is reusable. The best part is that carbon dioxide in the air will slowly change the red color back to goldenrod—just in time for your next class!

Flinn Magnetic Stirrer
The Flinn Hot Plate is a state-of-the-art device. The space-age ceramic top has excellent chemical resistance, high impact strength and an unsurpassed flat surface. The flatter the surface, the better the
heat transfer. An electrical input controller provides fine temperature control from ambient temperature to 540 oC. You can reach a rapid boil in just eight minutes— twice as fast as comparable hot plates! The square top is isolated from the die-cast aluminum base so your laboratory bench- tops are protected against heat damage. Heating elements are embedded in the ceramic top so it has no exposed or glow- ing heating elements; a power indicator light warns when the heating function is turned on.
With a very flat 7" x 7" stirring surface and cast aluminum base, the Flinn Magnetic Stirrer uses state-of-the-art ceramics to provide a remarkable top surface. The ceramic material offers high-impact strength, excellent chemical resistance and a bright white color to enhance solution visibility. Continuously variable stirring speeds from 300 to 2000 rpm using a main- tenance-free brushless DC motor. Supplied with a PTFE-coated stirring bar. Complete with three-wire grounded cord and plug. Replacement Ceramic Top is available sepa- rately. 120 volts, 30 watts.
