Beakers - Glass, Astm, Tall Form With Spout

ASTM Tall Form Glass Beakers with Spout, universally classified as Berzelius Beakers, are specialized laboratory glassware vessels engineered for processes requiring deep liquid containment and precision handling. Characterized by a height that is approximately twice their diameter, these tall-form beakers feature a slender profile that significantly reduces surface area, thereby minimizing evaporative losses and limiting splash-back during intensive stirring or titration routines.

Fabricated from high-purity borosilicate 3.3 glass, these beakers deliver outstanding thermal stability and chemical inertness, making them safe for direct heating on hot plates and highly resistant to aggressive acids, halogens, and organic compounds. The structural anatomy is completed with a heavy, uniform beaded rim to prevent mechanical chipping, a precision-formed pour spout for clean fluid dynamics, and a matte ceramic marking spot for easy labeling.

Key Features

• Manufactured from premium borosilicate 3.3 glass with a low coefficient of thermal expansion for optimal thermal shock resistance
  
• Slender, tall-form architecture optimized for liquid blending, electrolysis, and handling volatile solvents
  
• Strict adherence to uniform wall thickness gradients to prevent localized thermal hot-spots or mechanical cracking
  
• Clear, double-capacity graduation markings utilizing durable, highly visible fired-on white enamel
  
• Flat, ground-parallel base ensuring stable contact and maximum heat absorption from laboratory heating elements
• International Standards

Our tall-form glass beakers are engineered and manufactured in strict compliance with globally recognized testing and material parameters, ensuring seamless verification for international export and B2B contracts:

• ASTM E960 – Standard Specification for Laboratory Glass Beakers (Type II Tall Form Compliance)
  
• ASTM E438 – Standard Specification for Glasses in Laboratory Apparatus Manufacturing (Type I, Class A)
  
• ISO 3819 – International Harmonization Standards for Laboratory Glassware and Beakers
• Available in a broad spectrum of standard capacities (e.g., 50ml, 100ml, 150ml, 250ml, 400ml, 600ml, 1000ml). Customized client printing, specialized bulk export packaging grids, and batch-specific compliance certifications can be provided to support high-volume distribution networks.
