Circular Spirit Level Vials

Glass Circular Spirit Level-Borosilicate Glass, Liquid Color: Green, Red, Clear, Size As Require

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.
