Glass Bent Spirit Level Vials

Bent spirit level vials are used for leveling and angle measurement. They’re typically less sensitive than ground vials but are chosen over plastic vials when specific sizes, sensitivities, or line markings are needed.

Glass bent spirit level is a type of leveling instrument that uses a curved or bent glass tube filled with liquid and a bubble to determine the alignment or angle of a surface. When the bubble is centered between two markings on the vial, it indicates that the surface is level or at the desired angle, depending on the specific design of the level. These bent vials are typically made of glass for clarity and accuracy. They can be custom-designed to fit specific applications where straight vials might not be suitable, or where a particular curvature or angle measurement is required. They offer a durable and precise alternative to plastic vials, especially in applications that require custom sizes or markings.

Glass bent spirit level vials are typically made from the following materials:

• Glass: The vial itself is often made of clear, high-quality glass that provides clarity to easily view the bubble inside. The glass is chosen for its transparency and resistance to scratches.
• Liquid: Inside the vial, there’s a liquid, often a colored spirit (usually ethanol or methanol) that helps the bubble maintain its shape and move smoothly. The coloration, often green or yellow, enhances visibility.
• Bubble: The air bubble inside the vial is what indicates the level. Its movement within the vial, in relation to the vial’s markings or graduation lines, shows the alignment or angle of the surface.
• Sealant: The ends of the vial are sealed to prevent the liquid and bubble from escaping, and to ensure the longevity of the vial. The sealant material is chosen for its adhesive properties and resistance to the liquid inside the vial.
• Markings: Some vials might have graduation lines or other markings to indicate specific angles or measurements. These markings can be made with paints or inks that are durable and resistant to the liquid inside.
• Protective Housing (Optional): While not a part of the vial itself, some bent spirit level vials may be encased in a protective housing made of metal or plastic to provide added durability and resistance to impacts or environmental conditions.
