About RING AND BALL

RING AND BALL

Inexpensive device to show thermal expansion of metals. A brass ring and a 2.5cm ball are mounted on separate wooden handles of length 25cm. Ball, when cold, easily passes through ring, but does not pass through same ring when heated.

Efficient Softening Point Testing

The apparatus performs precise softening point tests on bituminous products, such as bitumen and coal tar, using a standardized ring and ball method. It permits testing of two samples simultaneously and incorporates controlled heating to assure consistent, reliable results every cycle. The laboratory-grade construction guarantees durability and accuracy.

Sturdy and Safe Laboratory Equipment

With a robust metal frame, heat-resistant borosilicate beaker, and foam-padded packaging, this apparatus is engineered for stability and safety in laboratory environments. Its corrosion-resistant materials support long-term frequent use, making it an essential investment for quality assurance laboratories.

FAQs of RING AND BALL:

Q: How do you operate the Ring and Ball Melting Point Apparatus for testing softening points?

A: To use the apparatus, place the brass rings and steel balls with your samples into the borosilicate beaker. Fill the beaker with the appropriate liquid bath, insert the provided glass thermometer, and begin heating at a controlled rate of approximately 5C per minute. The softening point is noted when the ball passes through the sample as it softens.

Q: What materials can be tested using this melting point apparatus?

A: This equipment is primarily designed for testing the softening points of bitumen, coal tar, and other similar bituminous materials. Its precise measurement range from 30C to 150C accommodates various standard bituminous test procedures.

Q: When is it recommended to test samples using double positions in this apparatus?

A: Double positions are ideal when comparative results are needed for two samples under identical conditions or for repeated tests to increase efficiency. Each test is conducted separately to maintain precision, with both results easily accessible for evaluation.

Q: Where can the Ring and Ball Apparatus be installed and used?

A: The apparatus is suitable for laboratory settings, including petroleum, road construction quality control, and research institutions. Its compact dimensions and robust construction make it easy to set up in standard lab workspaces.

Q: What is the process for ensuring accurate temperature control during tests?

A: Temperature is regulated via either the electric coil-type heater or manual heating, depending on the model. The glass thermometer provides real-time monitoring, ensuring that heating progresses at the specified rate and the accuracy of 1C is maintained.

Q: What are the key benefits of using this laboratory-grade apparatus?

A: Benefits include reliable, repeatable measurements, corrosion-resistant and stable construction, efficient two-sample testing, and secure packaging for safe transport and storage. It assures quality in material assessment, vital for manufacturers and suppliers involved in bituminous product production and testing.
