Acrylic Bubble Spirit Level Vial is a sealed tube made of acrylic plastic that contains a liquid, usually alcohol or a similar substance, and a visible air bubble. The vial often has reference lines inscribed on it. The position of the air bubble in relation to these lines indicates whether a surface is level. If the bubble is centered between the lines, it means the surface is horizontally or vertically level, depending on the orientation of the vial.
Acrylic, as a material, offers certain advantages for these vials. It’s transparent, allowing for clear visibility of the bubble, and it’s also durable and resistant to breaking or cracking, especially when compared to glass. This makes acrylic bubble spirit level vials particularly useful in environments where they might be subjected to rough handling or potential impacts.
Acrylic and PMMA (polymethyl methacrylate) are often used interchangeably in many contexts, which can be confusing. In fact, when people refer to “acrylic” in the context of materials like Plexiglas or Lucite, they’re actually talking about PMMA.
Given that PMMA is often what people mean when they say “acrylic,” vials made from either material are used in similar applications—construction, instrumentation, tooling, etc.
Both materials are non-biodegradable plastics. when comparing Acrylic Level Vials and PMMA Level Vials, you’re often looking at products made from the same material, just referred to differently.
