Buoyancy Balance Apparatus Manufacturer,Supplier and Exporter in India

Buoyancy Balance Apparatus (Product Code: SLE/CE/101) is a weighing system that measures a specimen in air and then suspended in water, used to find the specific gravity, density and water absorption of aggregates, concrete and rock in civil engineering laboratories. Materials-testing labs and engineering colleges choose it for its 6000 g capacity with 0.1 g readability and a mechanical lift that raises the water tank to the specimen. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Buoyancy Balance Used For?

The apparatus applies Archimedes' principle: a specimen weighs less in water by exactly the weight of water it displaces, so weighing it in air and immersed gives its volume and hence its density. The specimen, or a wire basket of soaked aggregate, hangs from the suspension hook beneath the balance. After the reading in air, the lifting device raises the tank until the specimen is fully submerged, and the immersed reading is taken without disturbing the hook.

Raising the water rather than lowering the sample keeps the load steady and the readings repeatable, which matters with 0.1 g resolution. When density work is finished, the balance serves as an everyday weighing device, so one bench unit covers both jobs. This makes it versatile laboratory equipment for technical institutes running aggregate, concrete and rock tests.

What to Specify When Ordering

• Number of complete systems (balance, frame, water tank and suspension hook)
• Whether density baskets for aggregate samples are also required
• Confirmation that your mains supply matches 220–240 V AC, 50–60 Hz

OEM Manufacturer

Jain Scientific Equipments Private Limited, which trades as ScienceLab, is the OEM for the Buoyancy Balance Apparatus. The system is made and assembled at the company's own licensed factory at Saha, Ambala, Haryana, India, and supplied direct from there.

Engineering colleges, testing laboratories, dealers and importers receive quotations from the manufacturer itself and can raise questions on spares or additional systems with the same team. Read about the company on the ScienceLab company profile.

Frequently Asked Questions

What are the capacity and readability of the Buoyancy Balance Apparatus?
The Buoyancy Balance Apparatus uses a balance with a capacity of 6000 g and a readability of 0.1 g. That range suits aggregate samples in a density basket as well as small concrete or rock specimens weighed in air and in water.

What is supplied with the Buoyancy Balance Apparatus?
The Buoyancy Balance Apparatus is supplied with the balance, a rigid support frame, a water tank mounted on a platform and a suspension hook. A density basket for aggregate is a separate item and can be added to the same quotation.

How is the specimen immersed in the Buoyancy Balance Apparatus?
In the Buoyancy Balance Apparatus, a mechanical lifting device raises the water tank through the height of the frame until the specimen hanging below the balance is fully immersed. The specimen stays on the hook, so the reading is not disturbed.

Can the Buoyancy Balance Apparatus be used for ordinary weighing?
Yes. The balance supplied with the Buoyancy Balance Apparatus may also be used as a standard weighing device, making it a versatile weighing system for the laboratory when density tests are not being run.

What power supply does the Buoyancy Balance Apparatus need?
The Buoyancy Balance Apparatus operates on 220–240 V AC at 50–60 Hz, with a power rating of 80 W. Let us know in your enquiry if your laboratory uses a different mains supply.

Who manufactures the Buoyancy Balance Apparatus?
The Buoyancy Balance Apparatus is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab) as the OEM, at its own licensed factory in Saha, Ambala, Haryana, India. For calibration-certificate questions, please ask us through the contact page before ordering.
