BEAKER BORO 3.3

Description

Borosilicate 3.3 Glass Beakers are the quintessential laboratory vessel, engineered for superior thermal and chemical resistance. Often referred to as “Griffin Beakers,” these low-form containers feature a wide cylindrical body and a pouring spout, making them ideal for stirring, mixing, and heating liquids.

Core Material Properties (Boro 3.3)

• Thermal Shock Resistance: Designed with a low coefficient of linear expansion ($\approx 3.3 \times 10^{-6} K^{-1}$), allowing the glass to withstand rapid temperature changes without cracking.

• Chemical Durability: Highly resistant to water, neutral and acid solutions, concentrated acids, and organic solvents. It also offers excellent resistance to alkaline erosion.

• High Temperature Limit: Suitable for continuous heating. It can withstand temperatures up to 500°C for short durations (though extreme caution is required for rapid cooling).

• Optical Clarity: Transparent, bubble-free glass ensures clear visibility for monitoring reactions and volume levels.

Key Product Features

• Uniform Wall Thickness: Ensures even heat distribution, which is critical for direct flame or hotplate heating.

• Reinforced Rim: Features a beaded rim to prevent chipping and increase mechanical strength during handling.

• Integrated Spout: Precision-molded spout allows for clean, drip-free pouring of liquids.

• Graduated Scale: Features high-contrast, permanent white enamel markings for approximate volume measurement (typically accurate within ±5%).

• Marking Spot: Includes a large, matte-finish white area for labeling samples with a pencil or marker.

Technical Specifications & Sizing

Common Applications

• Heating & Evaporation: Used over Bunsen burners (with wire gauze) or hotplates to boil liquids or concentrate solutions.

• Titration & Stirring: The wide mouth allows for easy access by magnetic stir bars or glass stirring rods.

• Reagent Storage: A temporary container for holding acids, bases, or standard solutions during an experiment.

• General Lab Use: Measuring out rough volumes of liquids for dilutions or buffer preparation.

Why Choose Boro 3.3?

While cheaper soda-lime glass may suffice for room-temperature storage, Borosilicate 3.3 is the industry standard for any task involving heat or aggressive chemicals. It is a durable, autoclave-safe, and long-lasting investment that ensures safety and reliability in both academic and industrial laboratories.
