An established, high quality, low cost instrument capable of measuring the rotation of optically active samples. It matches the performance of many of the digital instruments on the market.

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.

The instrument accepts sample tubes of lengths up to 220mm and is used for measuring concentrations and optical rotations in the food, sugar, flavours, fragrance, pharmaceutical and chemical industries as well as used extensively in schools and colleges.

For dark samples which absorb light the instrument has provision for adjustment, allowing more light to pass through the sample.

For calibration purposes verification of the Polarimeter can be made against fixed value quartz control plates.
