It consists of a copper vessel of 3"x2" with outer vessel as a superior quality teak wood box of size 9.5 x 9.5 x 11.5 cm fitted with bakelite lid with hole for thermometer and stirrer.

An instrument of great stability for quick, accurate handling. Life time stainless steel scales and verniers and fine achromatic optics make this a precision instrument of universal choice for normal experiments and for research. The instrument is designed for use in the vertical and horizontal plans.The vertical guide bar is made of gun metal and is of a special type. It rotates on ball centress having bearings and can be clamped in any position. The cast iron frame supporting the vertical guide bar is fitted with leveling screws. Range either 50cm or 100 cm.

For studying the construction and characteristic of a voltaic cell. It consists of copper plate, zinc plate and plastic jar without solution.

This cell is steady & reliable and may be used as open or close circuit works. It consists of a zinc rod immersed in a very dilute solution of sulphuric acid in an empty porous pot which in turn, is immersed in copper sulphate solution. This cell consists of copper sulphate solution. This cell consists of copper pot of approx. Size 5 ½ “x 3 ½ “. Chemicals are not included (only copper pot Daniel cell of size 5 ½” x 3 ½”, empty porous pot and zinc rod is provided).

Because of its higher e.m.f. (15 V) and lower internal resistance, this cell will deliver a stronger current for short period of time compared to the daniel cell. It consists of a plastic container 95 x 95 x 150 mm length x width x height. The rim is shaped to accommodate the cathode a zinc rod with terminal. A carbon anode with terminal is sealed in a filled porous pot containing the depolarizer. We provide filled porous pot for anode. Requires approx. 500 ml ammonium chloride electrolyte with zinc rod and filled porous pot. Supplied without electrolyte.

For demonstrating decomposition of water. This design is preferred for work of best precision. Platinum electrodes are used for electrolysis of water. The electrodes are mounted with rubber stoppers for insertion in the open ends of the voltmeter limbs. The glass unit has two connected limbs, integral with reservoir tube and funnel shaped bulb, with a stop clock at the top of each limb. Supplied with suitable metallic stand, helps to prevent accidental breakage. Glass parts are made from corning glass.
