Ring And Ball Apparatus (Electrical) Manufacturer,Supplier and Exporter in India

Ring And Ball Apparatus (Electrical) (Product Code: SLE/CE/89) is an electrically heated test set used to determine the softening point of bitumen and similar binders by the ring and ball method in highway and civil engineering laboratories. Each unit comes with a heat-resistant glass bath, tapered rings, a 9.5 mm steel ball, a ring holder and an electric hot plate with energy regulator. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM and a scientific lab equipment manufacturer in Ambala, India, at its own factory.

What Is the Ring and Ball Apparatus Used For?

Bitumen has no sharp melting point; it softens gradually as it warms. The ring and ball test puts a number on this behaviour: molten binder is cast into the tapered rings, a steel ball is placed on each disc, and the assembly in the ring holder is heated in the glass bath. The temperature at which the softened binder lets the ball sink through and reach the base is recorded as the softening point, which is used with penetration to grade paving bitumen.

The energy regulator lets the operator hold a steady, controlled rate of heating, which matters because a faster rise gives a misleading result. Stir the bath liquid gently for an even temperature, keep the balls centred on the discs, and read the temperature on a thermometer placed near the rings. The clear glass bath lets students watch the binder sag, which makes it a clear demonstration piece among engineering lab equipment in India for highway practicals.

What to Specify When Ordering

• Number of sets needed for your laboratory or student batches
• Whether a thermometer should be quoted, and the range your method requires
• Whether spare tapered rings or steel balls should be included — ask us
• Confirmation that your supply is 230 V, 50 Hz, single phase AC

OEM Manufacturer

This ring and ball apparatus is an original ScienceLab product: Jain Scientific Equipments Private Limited, which trades as ScienceLab, is its OEM and makes it at the company's own licensed factory at Saha, Ambala, Haryana, India. Laboratories deal directly with the maker instead of a trading intermediary.

Colleges, highway laboratories, dealers and importers are supplied factory-direct, and repeat orders or replacement rings, balls and glass baths can be requested from the manufacturer — just ask us. See the company profile for more about ScienceLab.

Frequently Asked Questions

What is the Ring And Ball Apparatus (Electrical) used for?
The Ring And Ball Apparatus (Electrical) (SLE/CE/89) is used to determine the softening point of bitumen and similar binders. Binder cast in tapered rings is loaded with a steel ball and heated in a glass bath until the ball sinks through.

What is included with the ring and ball apparatus?
Each Ring And Ball Apparatus (Electrical) is supplied with a heat-resistant glass bath, tapered rings, a steel ball of 9.5 mm diameter, a ring holder and an electric heater (hot plate) with energy regulator. A thermometer is not listed and can be quoted separately.

What power supply does the Ring And Ball Apparatus (Electrical) need?
The Ring And Ball Apparatus (Electrical) operates on a 230 V, 50 Hz, single-phase AC supply. Its heater has an energy regulator, so the operator can keep the rate of temperature rise steady throughout the test.

Why does the apparatus use a heat-resistant glass bath?
The heat-resistant glass bath of the Ring And Ball Apparatus (Electrical) withstands heating on the hot plate and lets the operator see the balls and binder clearly as they sink. Let the bath cool before washing it to avoid thermal shock.

Who manufactures the Ring And Ball Apparatus (Electrical)?
The Ring And Ball Apparatus (Electrical) is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own factory at Saha, Ambala, Haryana, India. Buyers in India and international markets receive quotations directly from the manufacturer.

What should an enquiry for the ring and ball apparatus include?
For the Ring And Ball Apparatus (Electrical), state the number of sets, whether a thermometer and spare rings or balls are needed, and your delivery location. Send the details through the contact page for a quotation.
