Lactometers (In a Plastic Container) Manufacturer,Supplier and Exporter in India
Product Code : EL-SLE-4620
Jlab Export is a leading Lactometers (In a Plastic Container) Manufacturer,and suppliers in India
Lactometers (In a Plastic Container) (code EL-SLE-4620) are borosilicate glass lactometers, each with its own plastic container, used to check milk through its specific gravity — for example to reveal added water — in school science, college dairy-science and general laboratory practicals. The scale reads 15–40 against a 20 °C reference temperature. They are made by Jain Laboratory Instruments Pvt Ltd (JLab) at its works in Ambala, India.

How Does It Compare with Other JLab Lactometers?
| Model | Body | Scale | Temperature details | Listed with |
|---|---|---|---|---|
| This lactometer (EL-SLE-4620) | Borosilicate glass | 15–40, divisions of 1.0 | Thermometer range 0–40 °C; reference temperature 20 °C (15 °C on request) | Plastic container |
| Lactometer (Test Of Milk) | Glass | 0–40, divided into 1.0 degree | Calibrated at 84 °F | Glass cylinder |
Choose this model when you want each lactometer kept in a plastic container and read against a 20 °C reference, or 15 °C if you ask for it. The Test Of Milk model is listed with a glass cylinder for the sample and an 84 °F calibration temperature, so it suits buyers who want the jar supplied with the instrument.
What Is the Lactometer Used For?
A lactometer is a hydrometer made for milk. It floats upright in a milk sample and sinks to a depth that depends on the milk’s density, so the scale at the surface gives a reading linked to its specific gravity. Adding water lowers the specific gravity of milk and the lactometer sinks deeper, which is why it is used to check milk for watering and to judge its richness. In schools it illustrates flotation and Archimedes’ principle — the class 9 NCERT science textbook names the lactometer as an application of that principle — and it appears in food-adulteration activities, college dairy-science and food-technology practicals, and vocational dairy courses.
To take a reading, pour the milk into a tall jar, check with the thermometer scale that it is close to the 20 °C reference, and lower the clean lactometer gently so it floats freely without touching the sides. Milk is opaque, so read the scale where the milk surface meets the stem. A lactometer reading alone cannot prove that milk is pure: skimming off fat raises the specific gravity while watering lowers it, so a sample that has been both skimmed and watered can still read normally — pair it with a fat test. After use, rinse the lactometer with clean water, dry it, return it to its plastic container, and keep it out of liquids hotter than its 0–40 °C thermometer range.
What to Specify When Ordering
- Reference temperature — 20 °C as standard, or 15 °C on request.
- Quantity — the minimum order is 10 lactometers; glass instruments can break, so plan a few spares for class sets.
- Sample jar — the hydrometer jar is a separate item; add it to the same enquiry if your lab has no tall jars.
- Fat testing — if you also measure fat content, include the Gerber milk fat testing machine.
Frequently Asked Questions
What does this lactometer measure?
The specific gravity of milk. The reading shows how dense the sample is, which points to its water content and richness — added water gives a lower reading. Like any hydrometer, it works on the principle of flotation.
What is the scale range of the lactometer?
15 to 40, in divisions of 1.0, as listed (15-40/1,0). The instrument is also listed with a thermometer range of 0 to 40 °C in 1.0 °C divisions.
At what temperature should milk be tested?
At or near the 20 °C reference temperature. A 15 °C reference is available on request, so state which one you need in your enquiry. Milk becomes less dense as it warms, so readings taken well away from the reference temperature need correcting.
Is a jar or cylinder included?
No jar is listed. Each lactometer comes with its plastic container; the hydrometer jar linked below is a separate catalogue item that can go on the same order.
Can a lactometer alone show that milk is pure?
No. It detects changes in specific gravity, but skimming raises the reading while watering lowers it, so the two together can cancel out. Dairy and food-testing labs therefore combine the lactometer reading with a fat test.
How does it differ from the Lactometer (Test Of Milk)?
Both are glass lactometers for milk. This one is borosilicate glass with a plastic container, a 15–40 scale and a 20 °C reference temperature; the Test Of Milk model is listed with a glass cylinder, a 0–40 scale and an 84 °F calibration temperature.
What is the minimum order and dispatch lead time?
10 units, each sold individually. Dispatch is usually within 7–10 working days, after every lactometer has been visually inspected; export transit time depends on the destination and shipping mode.
What should an export enquiry include?
The quantity, the destination country and port or city, preferred delivery terms such as FOB or CIF, any packing or labelling needs, and the tender reference if one applies.
Who manufactures these lactometers?
Jain Laboratory Instruments Pvt Ltd (JLab) makes them at its works in Ambala, Haryana, and quotes for them directly as the manufacturer.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a manufacturer of laboratory glassware and science teaching equipment in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. These lactometers come from JLab’s own works rather than from a trader, so schools, colleges, dealers and importers buy them factory-direct; every piece is visually inspected before packing, and repeat orders are handled by the maker. The company is registered under CIN U29309HR2017PTC069123 and holds MSME Udyam registration UDYAM-HR-01-0003849 (manufacturing enterprise). JLab exports worldwide and can ship to buyers in every region, for example Panama in Central America and the Caribbean, Samoa in Oceania, Mauritius in East Africa, Germany in Western Europe and Senegal in West Africa. Tender buyers will find details on the JLab lab tenders page.
