• The resonance tubes are made of borosilicate glass and have an outside diameter of 38 millimeters. The tube is 900 millimeters (35.43 inches) long. The white graduations are in metric and are fused to the tube. Use these resonance tubes in your physics classroom to study resonating waves or velocity of sound in air.
• Made from Borosilicate glass which is resistant to strain and breakage due to temperature changes.
• Size 38mm x 900mm.
