B.Sc IInd year IVth Sem. Apparatus : Halfshade (or biquartz) polarimeter, light source (sodium lamp for the half shade polarimeter or white light source for the biquartz polarimeter), measuring cylinder, beaker, physical balance with weight box, sugar, reading lens and reading lamp.

AP-851-A

Polarimeter Half shade with 200mm tube with graduated scale with vernier Abron

For determining the specific rotation of optically active substances. A corning glass tube (size 200 mm) is enclosed in a circular aluminum tube with top door for access and exclusion of external light. The circular scale is attached near to analyzer and a range of measurement is 0 - 360° Vernier moveable on the scale enables reading of optical rotation to 60 seconds. Rough and fine adjustment, provided with HALF WAVE MICA PLATE giving three parts field for easy setting adjustable half shadow angles. The instrument can be used on monochromatic light. The light when passes through a polarized sheet and then through the solution. The emerging light is then observed through a rotatable polarized lens analyzer which is used as eye piece. The angle of light is rotated and read directly of the circular scale. Supplied on the the adjustable stand, packed in cardboard box.
