Model D7 Polarimeter

Model D7 Polarimeter

The Model D Polarimeter and sodium lamp outfit has been the primary choice of leading industrial and academic institutions throughout the world, offering practical assessment of optically active materials combined with high accuracy measurement.

Changes in legislation, particularly within the sugar and pharmaceutical sectors, has demanded a shift towards digital instrumentation, however, the need for a high quality optical polarimeter is still paramount where circumstances dictate that an optical instrument should be used. Such applications include use in contract laboratories of low sample throughput and of course the continued use in both physics and chemistry departments within the education field.

Instrument body has been replaced with a new ‘low weight’ component that reduces shipping costs, significantly important where a number of instruments are supplied to one destination and the sodium

lamp has been replaced with a lightweight, low cost LED light source with an interference filter and integral intensity control. Retaining the measurement specification of the original Model D, the new D7 provides the user with one of the highest specification optical measurements of rotation at a fraction of the cost of its predecessor.
