Transparent Watch Glass 70 mm, Borosilicate Glass, Resistant to Chemicals and High Temperatures, 10 pieces

The 70 mm transparent watch glass is manufactured from borosilicate glass 3.3, providing excellent chemical resistance and low thermal expansion. Its larger size offers an extended surface for evaporation and crystal observation, making it ideal for laboratory experiments requiring more space. Maximum recommended temperature is 500°C.

Technical features:
• Diameter: 70 mm, suitable for larger surface applications
• Material: borosilicate glass 3.3, resistant to chemicals and high temperatures
• Transparent surface for clear substance observation
• Low thermal expansion, stable at high temperatures
• Smooth, flat surface, suitable for measuring and evaporation

Laboratory applications:
• Evaporation of liquids and observation of crystals or precipitates
• Weighing and measuring solid or liquid substances
• Can be used as a cover for laboratory beakers, Erlenmeyer flasks, or larger containers
• Suitable for complex chemical experiments and standard laboratory procedures
• Can be placed on contrasting surfaces to highlight the contents

Usage instructions:
The 70 mm transparent watch glass can be placed directly on liquids or solids during evaporation, allowing precise observation of crystal and precipitate formation. For maximum visibility, it is recommended to use it on dark surfaces or cover it with a contrasting layer.

Quantity: 10 pieces
This watch glass is a durable and versatile laboratory tool, providing precision and reliability for chemical experiments and laboratory measurements.
