These round bottom flasks come with two or three necks and are mainly used in distillation and extraction processes. In these flasks, one neck is centered and vertical and the other neck (in 2-necked)/necks (in 3-necked) maybe vertical and parallel; or at an angle to the centered neck.
These flasks are made of uniform thick glass. They have a spherical bottom that allows for more uniform heating and/or boiling of liquid. Accessories including different kinds of columns, thermometers, dropping funnels, boiling capillaries and others can be fitted, depending upon the application.
Our flasks are designed to deliver the best combination of thermal shock resistance, physical strength and resistance to chemical attack. All sizes come with white printing and also have a white area for marking with an ordinary pencil.
Round bottom flasks with 4 or 5 necks can also be customized.
