Made of borosilicate glass for clarity, strength, heat-, and chemical-resistance
Premium Materials: Reaction Flask is made from Borosilicate 3.3 Glass materials, which has a very low coefficient of thermal expansion, about one-third of ordinary glass. Resistant to high temperature and Resistant to 200 ° C temperature change.
the shape is a long glass cylindrical tube, with a coarse frit on the end of tube, which is convenient for filling adsorbents such as alumina. Some of the columns are welded with a thin glass tube at the end of the tube. the angle is 45°, which is convenient for installation or for liquid outflow.
Reusable: It can be reused by washing with warm water, which is more environmentally friendly and will not cause pollution to the environment
Great for Professional Laboratories, Classrooms & Household; Superior chemical durability and heat tolerance. Designed for use in professional laboratories, but is an ideal choice for science classrooms and household use.
