B+S D7 polarimeter

For over 40 years, the D-type polarimeter equipped with a sodium lamp light source has met the high-precision measurement requirements of optically active materials and has become one of the preferred models for leading industries and academic institutions worldwide.

To adapt to the development of industry regulations, especially in the sugar and pharmaceutical industries, digital products are gradually being used. However, in certain special requirements, it is still necessary to use a high-quality optical polarimeter. Such as laboratories for low flux sample processing, as well as physics and chemistry laboratories in the field of education.

Bellingham+Stanley has updated the original D-type polarimeter design to meet the demands of 21st century applications. The instrument itself is more lightweight, thereby reducing transportation costs; Sodium lamps have been replaced by a lightweight, low-cost LED light source with interference filters and overall brightness control. Keeping the measurement specifications of the original D-type instrument, the new D7 type instrument provides users with high specification optical rotation measurement, and its cost is greatly reduced.

The electronic tube of the D7 polarimeter has an angle scale and an International Standard Sugar Scale (ISS) sugar scale, with a length of up to 220 millimeters. The micrometer drum can provide accurate readings and offers a 200 millimeter sample tube. Scale range: 0 to 360 ° A and -30 ° Z to+130 ° Z, with accuracy better than ± 0.05 ° A and ± 0.1 ° Z.
