Butyro Refractometer Manufacturer,Supplier and Exporter in India
Product Code : EL-ELA-5501
Jlab Export is a leading Butyro Refractometer Manufacturer,and suppliers in India
Butyro Refractometer (code EL-ELA-5501) is a refractometer for fats, oils and similar products that reads directly on the oil (butyro) scale. A micrometer eyepiece reads that scale to 0.1, supplied tables convert readings to refractive index from 1.42 to 1.49 with an accuracy of 0.0002, and the prism box is water-jacketed for temperature control. It is made by Jain Laboratory Instruments Pvt Ltd (JLab) at its works in Ambala, India.

How Does It Compare with Other JLab Refractometers?
| Model | Scale and range (as listed) | Other listed details |
|---|---|---|
| This butyro refractometer (EL-ELA-5501) | Butyro (oil) scale read to 0.1; refractive index 1.42 to 1.49 to 0.0002 via tables | Water-jacketed prism box; achromatising device for white light |
| ABBE Refractometer | Refractive index nD 1.300 to 1.700 in steps of 0.001; sugar scale 0 to 95% | Liquids, solids and powders; mean dispersion; thermometer on the double prism |
| Refractometer | Digital, 0 to 85% Brix | Automatic temperature compensation; food-testing and teaching use |
Choose the butyro refractometer when your work is on butter, ghee, edible oils and other fats and you want readings on the oil scale used in those tests. The Abbe refractometer covers a much wider refractive index range for general work, and the digital refractometer is aimed at sugar (Brix) measurements.
What Is the Butyro Refractometer Used For?
A refractometer measures how strongly a sample bends light where it meets a glass prism; in the eyepiece this appears as a sharp border between a light and a dark field, and its position gives the reading. Each fat and oil has a characteristic refractive index, so the butyro-refractometer reading is a standard quality test for ghee, butter and edible oils and helps food-testing laboratories check purity and spot adulteration. Because refractive index changes with temperature, the water-jacketed prism box lets the prisms be held at a steady temperature during the test.
The instrument is used in dairy technology, food science and oils-and-fats chemistry departments of colleges and universities, in public-analyst and food-testing laboratories, and in quality-control labs at dairies and oil mills.
What to Specify When Ordering
- Quantity — the minimum order is 10 units.
- Temperature control — a thermostatic water bath is a separate item and can be quoted on the same enquiry.
- Other dairy-testing items — such as a milk-fat testing centrifuge, added to the same enquiry.
Frequently Asked Questions
What is a butyro refractometer used for?
For measuring fats in oils and similar products, with the reading given directly on the oil scale, also called the butyro scale. Food and dairy laboratories use the reading to check ghee, butter and edible oils.
What range and accuracy does it give?
The micrometer eyepiece gives an accuracy of 0.1 on the butyro scale. Using the conversion tables supplied, readings convert to refractive index from 1.42 to 1.49 with an accuracy of 0.0002, relative to the mean sodium lines.
Can it be used with ordinary white light?
Yes. A compensating (achromatising) device removes the colours from the borderline, so the instrument can be used with white light.
Why is the prism box water-jacketed?
For temperature control: the refractive index of fats and oils changes with temperature, so the prisms are kept at a steady temperature while readings are taken.
How does it differ from the ABBE Refractometer?
The Abbe instrument is listed for refractive index from nD 1.300 to 1.700 and a sugar scale, for liquids, solids and powders. The butyro refractometer reads the oil scale directly and covers the narrower 1.42 to 1.49 band in which fats and oils fall.
What should an export enquiry include?
The quantity, destination country and port or city, delivery terms such as FOB or CIF, packing or labelling needs and the tender reference if there is one.
Who manufactures this butyro refractometer?
Jain Laboratory Instruments Pvt Ltd (JLab) makes it at its works in Ambala, Haryana, India.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a manufacturer of optical, physics and laboratory instruments in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The refractometer is produced at JLab’s own works rather than bought from a trader, so colleges, laboratories, dealers and importers buy it factory-direct, every instrument is visually inspected before dispatch, and repeat orders are handled by the manufacturer. JLab exports worldwide and ships to buyers in every region — for example the Czech Republic in Eastern Europe, Brazil in South America, Afghanistan in South Asia, DR Congo in Central Africa and South Korea in East Asia. Tender information is on the JLab lab tenders page.
