- Constructed from high-quality borosilicate glass, ensuring exceptional clarity, strength, and resistance to heat and chemicals. - Features Borosilicate 3.3 Glass, which has a low coefficient of thermal expansion—only one-third that of standard glass—making it highly resistant to thermal shock and capable of withstanding temperature changes up to 200 °C. - The shadowless bottom design allows for undistorted light transmission, preventing dark spots when the flask is filled with liquid and illuminated from below, enhancing visibility and accuracy during experiments. - Eco-friendly and reusable; simply wash with warm water for cleaning, reducing environmental impact and waste. Applications: - Ideal for laboratory experiments requiring precise reactions and observations, thanks to its durable and clear construction. - Perfect for educational settings, such as schools and universities, where students can safely conduct experiments and observe chemical reactions. - Suitable for home chemistry projects or DIY enthusiasts looking for reliable glassware that can endure high temperatures and chemical exposure.
