- Material and clarity - Reaction Flask is made from borosilicate glass for high clarity, strength, and reliable chemical resistance. - Premium performance materials - Uses Borosilicate 3.3 glass, which has a very low coefficient of thermal expansion (about one-third that of ordinary glass). This material is resistant to high temperature and to temperature changes up to 200 C. - Light transmission and viewing - Shadow-less bottom design transmits undistorted light; when the tube is filled with liquid and viewed from the top with a light source beneath, no dark spots form. - Reusability and environmental impact - Reusable by washing with warm water, offering an environmentally friendly option that helps reduce pollution. Use scenarios - Laboratory observation with backlighting - Suitable for experiments where the liquid inside the flask is viewed from above using light placed underneath, providing a clear, shadow-free view of the contents. - Heating and monitoring reactions - Its high temperature resistance and low thermal expansion support heating experiments and rapid temperature changes without distortion or compromise to visibility. - Repeated use in routine experiments - Easy to clean with warm water and reuse, supporting ongoing workflows in teaching labs or research settings.
