Do they melt at the same rate? Why or why not? Includes: Aluminum base and plastic foam base, both with ring to prevent spillage; instructions. See Enlarge Click to Enlarge Lenz' Law (Hoops) This great demonstration teaches Faraday?s Law of Induction as well as Lenz?s Law. Show how passing a magnet through a complete loop causes the device to move. No movement at all occurs when using the split loop. See Enlarge Click to Enlarge Induction Kit This comprehensive kit contains all of the necessary pieces for an understanding of electrical induction, magnetic fields, electromagnets, motors, AC/DC motors, basic transformers, series and parallel transformers, and many other applications. The kit features snap together frames for laminated or solid core transformer frames, motor mounts, field coils, and Thompson ring experiments. Includes fitted case and instructions. Requires power supply and meter. 45-075 Induction Kit includes: • Laminated "U" core in plastic frame • Laminated "I" beam in plastic frame • Empty frame for iron cores or motor mounting • (2) small frames for attachments • 600 turn primary coil • 300 turn secondary coil • (2) empty coils for winding experiments • Long solid iron core • (2) short solid iron cores • AC induction motor in laminated frame • Coil of magnet wire for winding • Levitating Thompson ring • Magnetic motor rotor • (2) mini compasses • (2) bar magnets • Alligator clips • Rubber bands • Winding coil contacts • Aluminum Lenz' Law disc on shaft • Connecting wires with banana plugs • Sturdy fitted case • Instructions See Enlarge Click to Enlarge Linear Expansion Apparatus Dial Form (1206) This Linear Expansion testing device makes studying the expansion of metals simple and instantly visible to the student. A metal rod is inserted into the steam chamber and steam is applied. Expansion of the rod is immediately registered by the dial indicator that is mounted on one end. The heat jacket has three inlet tubes for water intake, outlet and thermometer insertion. Unit includes four metal rods 6mm x 60cm of aluminum, steel, copper, and brass. A steam source is not provided. See Enlarge Click to Enlarge Steam Generator (1873) A useful accessory for many experiments involving thermal energy. Constructed of a heavy gauge aluminum. Consists of a boiler, sample cup, tripod and two rubber stoppers with and without hole. The boiler is 100mm diameter x 170mm height, the stand measures 240mm in height. See Enlarge Click to Enlarge Ball & Ring Apparatus, Economy, Brass, 2 Piece (198-A) This unit demonstrates the expansion of metal with heat and its contraction when cooled. When a ball or ring on a handle is heated, the ball will not pass through the ring, but when cooled the ball passes through the ring freely. See Enlarge Click to Enlarge Convection Apparatus for Liquid (303) Convection of Liquid Glass Frame Illustrate the properties of convection currents! The water and dye-filled glass frame is heated at the bottom corner. When observed, the movement shows the path of the convectional current. (8" x 8-1/2" x 1/2"; .02Ib). See Enlarge Click to Enlarge Convection Apparatus for Gases (303-1) The enamel coated metal box has a sliding glass front and two glass chimney stacks. Smoke is introduced in one chimney using either smoldering paper or a punk stick. The smoke can be observed traveling down into the box and back out through the other chimney that stands over a flaming candle. The principles of convection currents and wind is made very clear through this demonstration. See Enlarge Click to Enlarge Calorimeter - Double Wall (304-1) Consists of an inner vessel (100ml) and out vessel (300ml) with a molded cover, rubber stopper, stirrer, and fiber washer to support & insulate the inner vessel See Enlarge Click to Enlarge Calorimeter - Electric (304-2) The cover contains a mounted heating coil of about 1.5 ohms resistance with standard binding posts for electrical connections. When connected to a 6-volt battery, this coil will cause a temperature rise of about 5 degrees Centigrade in 10 minutes. The supporting posts and coil are coated to prevent electrolysis. Comes complete with insulated handle on stirrer and single - hole rubber stopper. See Enlarge Click to Enlarge Compound Bar (309) A dramatic demonstration of the thermostat principle! Consists of a bimetal strip mounted in a wooden handle. Because of the unequal expansion of the two different metals, the bar will bend when heated which illustrates the operation of a thermostat. (10" x 3/4" x 3/4"; .2Ib). See Enlarge Click to Enlarge Heat Conductometer, 5 rods (312) 5 different metal spokes, aluminum, brass, steel, nickel, copper, extend from a center hub on a wooden handle. The hub is heated and the students watch as wax falls from each spoke in the order of conductivity. Includes wax. See Enlarge Click to Enlarge Aneroid Calorimeter (LSE) Introducing a “dry” calorimeter design that's five times more sensitive than traditional versions. It is absolutely safe because it uses no water. The one-pound core keeps heat loss to a minimum, allowing precise measurement of changes in temperature. Includes: die-cut styrofoam insulation; substantial one-pound aluminum core inside durable plastic housing; machined hole for easy insertion of thermometer. Full instructions include graphical workup. Use with 15-060 Specific Heat Specimens. You need thermometer. Wt: 70 g. Box: 7 x 4 3/4 x 5". See Enlarge Click to Enlarge Specific Gravity Blocks (LSE) These rectangular blocks of brass, aluminum, steel and copper are 13 x 13 x 50 mm in size. See Enlarge Click to Enlarge Mini Cubes of Various Types (LSE) Here?s a handy, low-cost set of five 10mm cubes that can be used in many experiments. What makes it unusual? It offers an array of the materials we actually use today. Learn about density, mass, volume, buoynacy, specific gravity and flotation while experiment with real-world materials. Our set includes one cube each of the following materials: Aluminum, Steel, Brass, Copper, Zinc. See Enlarge 1 2 3 [4] 5 [«Back ||Next »] Go to Top
