Buoyancy Balance
Buoyancy Balance (Product Code: SLE/CE/24) is a weighing system used to determine the density of concrete by weighing a specimen in air and then in water, in civil engineering and materials testing laboratories. Its rigid support frame carries a platform-mounted water tank that a mechanical lifting device raises to immerse the specimen hanging below the balance. The system is developed and made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

What Is the Buoyancy Balance Used For?
The buoyancy method relies on Archimedes' principle: a specimen weighs less in water than in air by the weight of water it displaces. From the two weighings the laboratory calculates the specimen volume and then its density, without needing to measure an irregular shape with callipers.
Because the water tank is lifted up to the specimen rather than the specimen being lowered by hand, the sample stays steady and the reading settles quickly. Check that no air bubbles cling to the specimen and note the water temperature for each test. When the frame is not in use for density work, the balance serves as an everyday laboratory weighing device, a space-saving arrangement for labs sourcing test and measurement instruments in India.
OEM Manufacturer
ScienceLab, the trading name of Jain Scientific Equipments Private Limited, developed this buoyancy balance system and is its OEM. The frame, tank platform and lifting arrangement are built at the company's own licensed factory at Saha, Ambala, Haryana, India, and the complete system is supplied factory-direct to engineering colleges, testing laboratories, dealers and importers.

Frequently Asked Questions
What is the Buoyancy Balance used for?
The Buoyancy Balance is used to find the density of concrete. A specimen is weighed in air and then in water, and the difference between the two weights gives its volume, from which density is calculated without measuring the specimen shape.
How does the Buoyancy Balance immerse the specimen?
The Buoyancy Balance uses a mechanical lifting device to raise the platform-mounted water tank through the frame height. The specimen, suspended below the balance on its cradle, is immersed smoothly without being lowered or disturbed by hand.
Can the Buoyancy Balance be used for ordinary weighing?
Yes. The balance supplied with the Buoyancy Balance can also be used as a standard weighing device, giving the laboratory a versatile weighing system for routine work when density tests are not running.
What is the capacity of the Buoyancy Balance?
The balance capacity and readability for the Buoyancy Balance are not stated in this listing. Tell us your maximum specimen weight and required resolution through the contact page, and the manufacturer will confirm a suitable configuration in the quotation.
Who manufactures the Buoyancy Balance?
The Buoyancy Balance system is developed and manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab) as the OEM at its licensed factory at Saha, Ambala, Haryana, India, and supplied directly to institutions, dealers and importers.
What should a Buoyancy Balance quotation request include?
A Buoyancy Balance quotation request should state the product code SLE/CE/24, the specimen types and weights you test, the quantity and the delivery location. Use the contact page or the enquiry cart to send it.
