Glass Bubble Level Vials
Glass Spirit Level Vials Available In Tubular,Circular And Bent Shapes Used For Measuring Levels
We specialize in crafting glass spirit bubble level vials using advanced technology. Our rigorous testing and competitive pricing extend to both standard and custom vials, ensuring high quality and performance.
Glass spirit level vial is a sealed glass tube containing a liquid, usually alcohol or a similar substance, and an air bubble. The position of the bubble indicates whether a surface is level or plumb. The vial is typically mounted within a frame or a tool. When the bubble is centered between the reference lines on the vial, it indicates that the surface is level (horizontally or vertically, depending on the orientation of the tool). Glass vials are preferred by some for their clarity and resistance to scratching or clouding compared to plastic vials.

Circular spirit level, commonly known as a “circular level,” is a tool used to determine if a surface is horizontal. A glass circular spirit level specifically employs glass to gauge whether a surface is level or vertical (plumb). Glass circular spirit level combines the advantages of the circular spirit level design with the clarity and precision of glass construction, making it a favored choice for applications demanding high accuracy and clear visibility.
Design and Structure
Shape: As suggested by its name, this level has a circular or round shape.
Material: Made of glass, which provides clarity for better accuracy in readings.
Interior: Contains a liquid, usually a clear spirit or ethanol solution, with a visible air bubble.
Markings: The top transparent surface of the level often has a central circle marking or sometimes multiple concentric circles.
Functionality
Bubble Position: When the surface upon which the level rests is perfectly level, the air bubble inside the liquid will center itself within the marked circle.
Inclination: If the surface is tilted or inclined in any direction, the bubble will deviate from the center.
Advantages
Clarity: The use of glass provides clear visibility of the bubble, aiding in precise readings.
Durability: Glass vials, when made from high-quality materials, can be scratch-resistant and long-lasting.
Accuracy: Due to their precise manufacturing, they often offer high accuracy.
Applications
Tools & Devices: These levels are often found embedded into professional equipment or devices, such as cameras, tripods, or precision instruments.
Industrial & Lab Equipment: Used in machinery or lab apparatuses that require accurate level validations.
Construction: Incorporated into specialized tools or used as standalone tools for precise leveling tasks.

Glass Bent Spirit Level Vials, Liquid and Specifications
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.
