Hartle’s Optical Disc, Rotatable
For exploring the various concepts of optics involving reflection and refraction using ray tracing technique. Comprises a sheet metal disc, about 30cm in diameter, painted white at the top with clamping assembly at its underside for mounting it on a vertical support rod in either of horizontal or vertical plane and is rotatable about its axis. The
upper side of disc has a circular scale along its rim graduated 90º-0-90º- 0-90º × 1º and divides the disc in four equal quadrants with its center clearly marked. Shapes of various optical elements also clearly marked on the disc to facilitate their placement while performing experiments. The clamp at the underside has metal bar projecting
radially outside with adjustable lamp holder mounted at the other end with an adjustable collimating lens to get divergent, convergent or parallel beam as required. A rotatable disc attached in front of collimating lens provides option of single, double, triple or quadruple slits for range of experiments. Complete assembly mounted on stable
cast metal heavy base. Supplied complete with reflective components – one each of plane glass mirror, polished semi-circular cylindrical mirror; and set of 6 refractive components, acrylic blocks (prisms) – one each of semi-circular, bi-convex, bi-concave, right angled prism, equilateral prism and trapezoidal prism. All optical elements provided with powerful magnets at their bottom for placing them securely on the disc in either of horizontal or vertical disc position. The bottoms of all refractive components are frosted to minimize internal reflections and revealing the path of light as it passes through.

Hoffmann Voltameter
Hoffman Voltameter (PTFE) with electrodes, Used for demonstrating
the decomposition of water, determination of chemical composition by electrolysis and with
applications in the evaluation of the electrochemical equivalent of hydrogen. The apparatus
should be set up vertically using a clamp and stand to hold it safely. Connect the terminals to a DC power source. Matches will be required to test for gases.
Chemicals required:
Water, molar sodium, or potassium sulphate or sulphuric acid.
Supplied in neat, well-protected packing case.
The glass unit has two connected limbs, each of approximately 50ml capacity
(graduated 2 – 50ml), integral reservoir tube and funnel-shaped bulb, with a stopcock
at the top of each limb.
Supplied with electrodes, 2 carbon and 2 platinum. • Requires 12V power supply.
