Double Neck Round Bottom Flasks can be used for a variety of applications such as capturing and collecting material and also used for boiling off material through distillation. These flasks are double neck with a ground 24/40 joint and require the application of vacuum grease to the ground surface when using the flasks in a vacuum application. The second neck of this flask can also be used for a thermometer port or for introducing material into the flask with a glass funnel. When laying these flasks down it is always recommended to use a cork stand for the flask to prevent breakage and keep the flask upright.
