Rasayan Glass Beads N.G. Without Holes

"Rasayan Glass Beads N.G. Without Holes" likely refers to a specific type of glass beads manufactured by Rasayan that do not have holes. Glass beads without holes are commonly used in laboratory experiments and industrial processes for various purposes such as mixing, stirring, heating, and insulation. They are often made of borosilicate glass, known for its high resistance to thermal shock and chemical corrosion. The "N.G." in the description may stand for "non-graduated," indicating that these beads do not have any markings or gradations on their surface for measurement purposes. These glass beads serve as versatile tools in laboratories and industries, finding applications in chemistry, biology, material science, and engineering. They can be used in conjunction with various equipment and techniques for specific experimental requirements.
