Friction Rod – Glass (30 cm × 12 mm)

This Glass Friction Rod is a high‑quality, durable rod designed for electrostatic experiments in school physics laboratories. Measuring approximately 30 cm in length and 12 mm in diameter, it is ideal for demonstrating charge generation by friction, electrostatic attraction and repulsion, and the behaviour of insulating materials when rubbed with suitable cloths (e.g., silk or wool).

Made from smooth, high‑clarity glass, the rod produces a strong positive electrostatic charge when rubbed, making it essential for teaching fundamental concepts in electricity and static phenomena.
