Butyro Refractometer physilab Butyro Refrectometer :-Measurement
of fats in oil and other such products giving a reading directly in
terms of the oil scale also known as butyro scale, the micrometer
eye-piece allows an accuracy on this scale of 0.1 and the oil scale may
also be converted into a refractive index scale using conversion tables.
This allows measurements on materials with index of refraction in the
range of 1.42 to 1.49 with an accuracy of 0.0002 as tables are supplied
for converting oil scale reading into index of refraction, relative to
mean sodium lines.The prism box is water jacketed for temperature
control and a sample axiomatizing device enables the removal of all
colours from the border lines thus enabling the instrument to be used
with white light..
