STUDENT POLARIMETER

  STUDENT POLARIMETER MODEL PLM-8 (CAT NO. G-8901)
G-8901
(Click on the image to enlarge)
Most suitable instrument for measuring degree of rotation of plane-polarised light by solutions of optically active substances like sugar solutions etc. The instrument is mostly used in colleges and laboratories.
  • C.I. casted heavy base with adjustable height stand.
  • Workable tube – length 200mm.
  • Graduated circular scale 0 - 360° (In single degree division) every tenth line numbered.
  • Vernier has least count 0.1° and rotatable with analyzer for measuring the degree of rotation.
  • Fine motion for rotation of vernier is provided by knurled head screw.
  • Analyzer and polariser are made of Polaroid.
  • Bi-quartz is used for shade system (half shade system is also available). It is workable on natural as well as sodium light.
  • Ramsden eye-piece 8x is focusable by hand adjustment.
  • The instrument is supplied with 200mm length polarimeter tube.
  • The instrument is packed in strong cardboard box.
Optional : 100mm length polarimeter tube & sodium light source are available at extra cost. Polarimeter has black stoving painted and chrome plated parts.
