Glass Beaker with Handle, Boro3.3

This glass beaker with a handle is made from borosilicate 3.3 glass and comes in 250ml, 400ml and 600ml sizes, for safe, comfortable handling of hot liquids in the lab.

These borosilicate glass beakers with handles are designed for handling hot liquids, aggressive chemical solutions and volatile mixtures safely. Unlike standard beakers, they have a moulded glass handle that keeps your hand away from heat and hazardous spills. They're made from Type 1, Class A borosilicate glass (Boro 3.3), which handles heat and chemicals very well. They're a sensible safety choice for high school science classrooms, university biochemistry labs and industrial processing.

Sizes

Each size is proportioned for a stable centre of gravity and controlled pouring:

• 250ml (Boro 3.3): The go-to size for classroom demonstrations, micro-titrations and pouring hazardous stock solutions.
• 400ml (Boro 3.3): A middle size for mixing larger amounts of reagents, boiling aqueous solutions and preparing samples.
• 600ml (Boro 3.3): For heating larger volumes of solvent, bigger biochemistry experiments and transferring hot media.

Key Product Features

• Heat-resistant handle: A thick, reinforced glass handle keeps your skin away from the hot vessel, which helps prevent dropped beakers and burns.
• Low-expansion borosilicate 3.3: A very low coefficient of thermal expansion makes these beakers highly resistant to thermal shock, autoclavable up to 121°C and safe for direct hotplate heating.
• Chemical resistance: Highly resistant to aggressive acids, halogenated compounds, saline mixtures and strong alkaline bases, without clouding, etching or leaching ions into your samples.
• Matte white graduations: High-contrast, easy-to-read metric markings and a matte writing area for labelling samples.
• Pouring spout: A shaped spout breaks the surface tension of the liquid, giving a clean, drip-free pour.
• Product of China

Recommended Applications

• Safely preparing, stirring and boiling exothermic or concentrated acidic solutions.
• Transferring hazardous chemical waste or boiling-hot agar and culture media from the autoclave to Petri dishes.
• A safer-to-grip alternative to standard beakers in busy student lab classes.
