DADAKEWIN 500mm Graham Condenser, Joint 24/24, Borosilicate 3.3 Glass Standard Ground Mouth Heat Resistant Thick Glass Customizable Scientific Lab Condensers- Pack of 1 (Size : 500mm/24 * 2)

Packing: 1 piece/pack, 500mm Graham Condensers, Joint 24/24, Standard Ground Mouth
Heavy duty design, reusable, ground glass joints allow precision connection to jointed glassware.
Premium Materials: Graham Condensers 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.
Graham Condensers's inner core tube is a water condenser which two glass tubes are tightly intertwined into a spiral, which increases the length of the inner core tube and expands the cooling area. The steam is passed through the outside of the inner tube, which is not only cooled by water, but also by natural air. The cooling effect is better, and it is suitable for backflow.
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.
