The magnifier i fitted with a precision lens of 150mm diameter and with an optical glass lens of 3x. It has maximum possible power for a lens of its size, consistent with gives fatigue- free, stereo view equipped with round fluorescence tube (22 Watt ) which has shadow -less illumination. It is fitted o a universal stand fully adjustable verically and horizontally, works on 220V A.C

To calculate dielectric constant of liquids and solids. The instrument consists of high frequency oscillator of tuneable with outer gang condenser optimum tunning is indicated on meter. The change after placing dielectric between parallel plates is again detected and difference noted for calculation.

To determine velocity of ultra sonic wave) Complete apparatus with R.F. Oscillator 3-8 Mhz, Crystal with tank, Specto meter of 9" bed, Sodium Lamp with Wooden Box and Transformer.

Spherical pattern, the volume of the bottle is accurately adjusted at 27° C to the value etched on the surface. The bottle and capillary stopper are numbered for identification made from borosilicate glass.
