U Shaped Glass Tube for Laboratory Use

This high-quality U-Shaped Glass Tube is an essential piece of equipment for any physics or chemistry laboratory, classroom, or research setting. Perfect for illustrating the fundamental principles of fluid statics and pressure measurement, this U-shaped tube provides a clear, visual, and accurate method for determining pressure differences and densities of liquids.

Key Product Features and Benefits of the U-Shaped Glass Tube:

• Versatile U-Shape Design: The classic U-tube configuration (as seen in the photos) is the standard for manometers. It allows for the easy containment of a measuring fluid (like water, mercury, or colored liquid as shown) and facilitates the comparison of pressure between two points.
• Premium Borosilicate Glass Construction: Crafted from durable, heat-resistant, and chemically inert glass, ensuring longevity and safety in the lab. The clear glass provides excellent visibility for observing fluid levels and menisci (as visible in the images).
• Integrated Scale for Precision (As per the photo with the ruler): One version of the product features a permanently marked, calibrated scale (typically in millimeters or centimeters). This allows for highly accurate readings of the height difference ($h$) between the two liquid columns, which is critical for calculating pressure differentials ($\Delta P=\rho gh$).
• Multiple Applications: Ideal for various experiments, including:
  • Measuring gauge pressure (pressure relative to atmospheric pressure).
  • Demonstrating Pascal’s Principle and the concept of hydrostatic pressure.
  • Determining the density or specific gravity of an unknown liquid by using a reference fluid.
  • Illustrating the principles of osmosis and diffusion in advanced biology setups.
• Educational Excellence: An indispensable tool for teaching fluid mechanics, thermodynamics, and physical chemistry concepts at high school, college, and university levels. Its simplicity makes it easy for students to set up, conduct experiments, and understand complex principles.
• Sturdy and Reusable: Designed to withstand the rigors of a busy lab environment. Easy to clean and reuse for countless experiments.
