Butyro Refractometer

Butyro Refractometer

Product Code : JA-ELA-5501

The Butyro Refractometer (SKU JA-ELA-5501) is a refractometer made by JaincoLab for measuring fats, oils and similar products, giving its reading directly on the oil scale, also called the butyro scale. A micrometer eyepiece reads this scale to 0.1, and conversion tables supplied with the instrument turn the butyro reading into refractive index over 1.42 to 1.49 with an accuracy of 0.0002, relative to the mean sodium lines.

Specifications

The measuring range, reading accuracy and prism arrangement listed are shown below.

Applications of the butyro refractometer

  • Butyro-refractometer readings of ghee, butter and other fats in dairy laboratories
  • Refractive index of edible oils in food testing
  • Food science and dairy technology practicals

Scope of supply and ordering

The refractometer is supplied with its butyro-to-refractive-index conversion tables; water circulation arrangements, quantity and packing are confirmed on the quotation.

Frequently asked questions

What is the butyro scale?
The oil scale on which the instrument reads fats and oils directly; supplied tables convert it to refractive index.

Why is the prism box water jacketed?
So that water at a set temperature can be circulated, because refractive index changes with temperature.

Does it need a sodium lamp?
No. A compensator removes colour from the border line, so it can be used with white light.
