Polarimeter Laurent's Half Shade Student

Product Cat # PH0924

QTY


Ideal for basic lab applications and  determining the specific rotation of optically active substances. This rugged unit is mounted on a heavy casted streamlined body. It works on the principle of partial shade and can accommodate glass  tubes up to 200 mm length. The reading is done via the eyepiece with  verniers. Despite the classic design with polarizer and analyzer,. The light source must be monochromatic light only i.e Sodium Vapour Lamp. (Not Included in Supply) The circular scale is attached near the analyzer and the range of measurement is 0-360°. A movable vernier on the scale enables reading of optical rotation to 60 seconds. The well known variable half waveplate effect is used to obtain a balance between the two halves of a circle when viewed through an eyepiece. The reading is then taken from the scale.8

    It is  used for measuring concentrations and optical rotations in the food, sugar, flavours, fragrance, pharmaceutical and chemical industries. This polarimeter model is also extensively used in schools and colleges as an educational tool. When light passes through a polarized sheet and then through the solution, the emerging light is observed through rotatable polarized lens, analyzer which is used as eyepiece. The angle of light is rotated and read directly on the circular scale. Supplied on the adjustment stand, Packed in cardboard box with working manual.
