NEW Lippich Type Polarimeter (Schmidt & Heensch)
A precision instrument for measuring the rotation of the plane of polarization of all optically active substances. Big advantage is its glass circle instead of a metal cir cle. T h e scale on glass, instead of on metal, in con junction with a micrometer plate, permits direct read ing without vernier, resulting i n greater speed and pre cision of reading. Glass circle is rigidly connected with the analyzer and carries t w o scales, an angular scale in degrees arc, and a scale in international sugar degrees. Sodium vapor lamp is an integral part of the instrument and is always in alignment and ready for use. Model A with receiving trough for tubes up to a length of 220 mm. Model Β with receiving trough for tubes up to a length of 400 mm. Bulletin
