Our Laboratory Watch Glass 75mm  are multi-functional essentials for any chemistry, biology, or physics lab. Made from high-transparency, heavy-duty clear glass, these circular concave dishes are designed for everything from simple evaporation to serving as a protective cover for beakers. With a robust 2mm thickness, they offer significantly higher durability and resistance to chipping compared to standard thin-walled alternatives.

Key Features

• Reinforced 2mm Thickness: Extra-thick glass construction provides superior mechanical strength, making these watch glasses more resistant to thermal stress and physical impact.

• Precision Ground Edges: Every piece features smooth, fire-polished or ground edges to ensure safe handling and a snag-free fit on beaker rims.

• High Chemical Resistance: Resistant to most acids, alkalis, and organic solvents, ensuring no leaching or contamination during sensitive experiments.

• Stable Concave Design: The classic shallow curve is perfect for weighing small quantities of solids or observing crystal growth during evaporation.

• Multi-Purpose Utility:

  • Beaker Covers: Prevents dust contamination and reduces evaporation.

  • Observation Dish: Ideal for low-power magnification of small specimens.

  • Drying Surface: Perfect for small-scale solid-state drying.
