Key Features
- Thermal & Chemical Resistance: Fabricated from Borosilicate Glass, virtually inert to acid vapors and organic chemicals.
- Precision Ground Flanges: Uniformly flat ground base rim ensures reliable vacuum sealing with minimal grease or gasket compression.
- Heavy-Wall Construction: Engineered to withstand standard laboratory vacuum conditions without implosion risk.
- Distortion-Free Optical Clarity: Annealed borosilicate provides undistorted 360-degree visibility for specimens, vacuum gauges, and internal apparatus.
Applications
Widely used in vacuum chamber testing, botanical and zoological archival preservation, pharmaceutical desiccation, physics classroom demonstrations, and specialized industrial component encapsulation.
