Useful for experiments requiring heating by means of steam. Made of heavy gauge Aluminum sheet to provide sturdiness and durability for withstanding high boiling pressures, with riffled nozzle for steam outlet. Consists of boiler assembly, two rubber stoppers, one solid and one with a hole for thermometer, one sample cup with handle and tripod stand assembly.
* Steam Generator

Catalogue No: 1060390

Ideal for comparison of thermal conductivity of different metals quickly and conveniently. Features liquid crystal indicators mounted in robust holders. Four identical metal bars of same shape and size, each of different metal: copper, aluminumm, brass and steel held firmly in a rigid moulded plastic carrier with a hole for convenient suspension. Thermal conductivity value of each bar is clearly marked. The sensitive liquid crystal temperature indicators working in low temperature range are attached to each of the four metal bars and are marked at 1cm interval to facilitate charting the movement of temperature gradient. The rate of heat flow is indicated by timing the colour change across these markers. The demonstration requires only a container of hot water, thus doing away with open flames, hotplates, or messy melting wax method of comparison with result in a very short time. Timing the heat pulses enables estimation of the relative conductivities.

Catalogue No: 1060340/1

Comprising strips of four metals, one each of copper, iron, Aluminum and brass arranged symmetrically on a wooden frame with the strips meeting at the center. Outer ends of the strips has small recesses for holding paraffin wax.
* Metal Strips mounted on circular wooden frame

Pack of (Pcs): 1

Catalogue No: 1060300

Demonstrates how the bending due to differential expansion of two different metal strips can be used for operating the thermostat for temperature control. A vertically mounted bimetallic strip bends with the rise in temperature causing it to open the electrical contact and closing the same on cooling, thus controlling the switching ON/OFF of the circuit. Consists of binding posts for connection to low current circuits and adjustable contacts.
* Thermostat Model

Catalogue No: 1061060

Demonstrates the principle of ventitation convection currents in air. Comprises a sheet metal enclosure with open sliding glass front and two circular openings at the top for mounting glass chimneys. Air heated by a candle placed beneath one of the chimneys with glass door closed, causes the flow of convection currents, which can be observed by bringing a smoldering string near the top of other unheated chimney. Supplied without candles.
