Glass Beaker with Handle, Boro3.3

Borosilicate Glass Beakers with Integrated Handle (250ml, 400ml, 600ml) for safe, ergonomic, and high-thermal liquid handling for intense laboratory environments.

The Borosilicate Glass Beakers with Handles is specifically engineered for handling hot liquids, aggressive chemical solutions, and volatile mixtures safely. Moving away from traditional standard beakers, these vessels feature a molded glass handle that isolates the user's hand from extreme temperatures and hazardous spills. Forged from industry-standard Type 1, Class A Borosilicate Glass (Boro 3.3), these beakers exhibit superior thermal stamina and ultimate chemical defense. They are critical safety assets for high school science classrooms, university biochemistry labs, and industrial processing stations.

Dimensional Specifications

Each option in this lineup is carefully proportioned to balance structural center-of-mass stability with precise liquid management:

• 250ml Capacity (Boro 3.3): The go-to size for standard classroom demonstrations, micro-titrations, and pouring hazardous master batches.
• 400ml Capacity (Boro 3.3): An ideal intermediate volume optimized for mixing larger chemical reagents, boiling aqueous solutions, and sample preparations.
• 600ml Capacity (Boro 3.3): High-volume profile built for aggressive bulk solvent heating, larger biochemical experiments, and transferring hot media.

Key Product Features

• Ergonomic Heat-Resistant Handle: Features a thick, structurally reinforced glass handle designed to shield skin from searing vessel heat and dynamic thermal shifts, preventing accidental drop-shatters or hand burns.
• Ultra-Low Expansion Borosilicate 3.3: Boasts an exceptionally low coefficient of thermal expansion. This makes the beakers completely thermal-shock resistant, fully autoclavable up to 121°C, and safe for direct hotplate heating.
• Industrial Chemical Immunity: Highly resistant to aggressive acids, halogenated compounds, saline mixtures, and strong alkaline bases without clouding, etching, or leaching ions into your samples.
• Precision Matte-White Graduations: Features high-contrast, easy-to-read metric graduation markings and a dedicated matte finish note-writing block for rapid, clear sample labeling.
• Spill-Free Pouring Spout: Contoured with an optimized low-form pour spout that breaks liquid tension perfectly, allowing for a tight, drip-free fluid stream during intricate volume transfers.

Recommended Applications

• Safely preparing, stirring, and boiling highly exothermic or concentrated acidic solution sets.
• Transferring hazardous chemical wastes or boiling-hot agar/culture media from autoclaves to petri dishes.
• Serving as an advanced, safe-to-grip alternative to traditional handle-less beakers in busy student laboratory classes.
