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 pressure equalizing dropping funnel can keep the internal pressure unchanged. One is to prevent back suction, the other is to make the liquid in the funnel flow down smoothly, and the third is to reduce the influence of the added liquid on the gas pressure, so as to measure the gas volume more accurately.
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.
