Refractometer is an excellent control instrument & has been adopted in many laboratories.

• Any liquid, Plastic or Solid,with a definite refractive idea that will permit the setting border line of total reflection under the cross line can be read to three decimal places & estimated to fourth. 
  
• The instrument is built on a heavy base that maintains stability at any inclination.
  
• Two sets of amicy prisms, rotated in opposite directions by a knurled head, achromatize divided line under observation & provide necessary date for determination of dispersion of sample. 
  
• A Scale is provided for determining the degree of rotation of prism. Scale readings are form 1.30 to 1.70 & are easily read by a magnifier & reflector system water jackets around the prism provided and means of temperature control.
  
• A thermometer is regularly supplied as well as a small of monobromonaphthalene in wooden case.
