Lactometer (Test of Milk) Manufacturer,Supplier and Exporter in India

Lactometer (Test of Milk) (Product Code: SCL248/040) is a glass floating instrument used to check the specific gravity of milk, and so reveal added water, in school, college and dairy-training laboratories. Home-science and food-adulteration lessons use its 0–40 scale, divided into 1.0 degree steps with an accuracy tolerance of ±0.5 and calibrated at 84°F. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer of biology lab equipment in India, at its own factory in Ambala.

Specifications

What Is the Lactometer Used For?

Mix the milk sample gently so that the cream is evenly spread, pour it into the cylinder without making froth, and lower the lactometer in slowly until it floats freely without touching the wall. Once it settles, read the scale at the level of the milk surface. Pure milk gives a reading within its normal band, while added water makes the lactometer sink deeper and show a lower figure. Students can compare fresh milk with samples diluted in known proportions to see the trend for themselves, which makes the instrument a practical biology teaching aid in India for lessons on food adulteration.

Because the scale is calibrated at 84°F, milk that is much colder or warmer will give readings that need correcting. Check the sample temperature with a thermometer first, then either bring the milk close to 84°F or apply the correction your syllabus or dairy method specifies. Rinse the lactometer and cylinder with water straight after use so that milk solids do not dry on the stem and blur the scale.

OEM Manufacturer

The Lactometer (Test of Milk) is made by Jain Scientific Equipments Private Limited, which trades as ScienceLab and is the OEM (original equipment manufacturer) of this instrument. Production takes place at the company's own licensed factory at Saha, Ambala, Haryana, India, so dairy-training centres, schools and dealers deal directly with the maker instead of a middleman. Questions about the scale, repeat orders and replacement pieces go to the same team; just ask us. Background on the company is on our company profile.

Items that help you run the milk test correctly:

• Thermometer Alcohol — checks that the milk is near the 84°F calibration temperature.
• Thermometer (Digital) — a quicker way to read sample temperature for a whole class.
• Beaker — for mixing samples and preparing diluted milk for comparison.
• Measuring Cylinder — measures water and milk accurately when making known dilutions.
• Brush — cleans the cylinder once the milk has been rinsed out.

Frequently Asked Questions

What does the Lactometer (Test of Milk) measure?
The Lactometer (Test of Milk) indicates the specific gravity of milk as a reading on its 0–40 scale. Because added water lowers the density of milk, a reading below the normal band for that type of milk suggests the sample has been diluted.

How accurate is the Lactometer (Test of Milk)?
The Lactometer (Test of Milk) has a 0–40 scale divided into 1.0 degree steps with an accuracy tolerance of ±0.5. That resolution suits classroom demonstrations and routine screening of milk samples, though formal dairy testing may call for further laboratory methods.

Why does the 84°F calibration matter?
The Lactometer (Test of Milk) is calibrated at 84°F, so its readings are directly valid only when the milk is at that temperature. Colder or warmer milk has a different density, and its reading needs the temperature correction given in your syllabus or dairy method.

Is a cylinder supplied with the Lactometer (Test of Milk)?
The Lactometer (Test of Milk) is described as a glass body made up of the lactometer and a cylinder. Please confirm the exact contents on your quotation through our contact page so that each bench receives the complete set it needs.

Can a lactometer alone prove that milk is adulterated?
No. The Lactometer (Test of Milk) is a quick screening test for dilution with water. Some adulterants can hide a low reading, so any formal finding of adulteration needs further analysis in a food testing laboratory.

Is a calibration certificate available for the Lactometer (Test of Milk)?
Calibration-certificate availability for the Lactometer (Test of Milk) should be discussed with us before you order. Tell us what documentation your institution or dairy needs, and we will confirm what can be provided with the batch supplied.

Who manufactures the Lactometer (Test of Milk)?
Jain Scientific Equipments Pvt Ltd (ScienceLab) is the OEM manufacturer of the Lactometer (Test of Milk), code SCL248/040. It is made at the company's own licensed factory at Saha, Ambala, Haryana, India, and sold factory-direct to schools, dairies and distributors in India and international markets.
