Beschreibung
DURAN® flat flange bell jar with opening in neck is a laboratory glass vessel designed for vacuum applications and experiments conducted under reduced pressure. Equipped with an NS 34/35 ground joint and a diameter of 215 mm, it pairs with a vacuum experiment plate to enable observation of reaction processes in the rough- and fine-vacuum range. The jar is produced from borosilicate glass 3.3, providing excellent chemical resistance together with mechanical durability. A standardised ground joint ensures a reliable seal, while the opening in the neck allows attachment of supplementary apparatus. Permanently fired white print markings remain durable and clearly legible. Offered as a single unit with a net weight of 2,9 kg, this bell jar from manufacturer Duran/DWK Life Sciences supports vacuum-chamber work, under-pressure trials and both research and teaching environments that require controlled atmospheric conditions. The optical clarity of the glass permits unobstructed viewing of internal events, and the sturdy construction withstands the mechanical stresses associated with laboratory vacuum use.

Questions about DURAN® Bell Jar, with aperture in neck
What is this article?
DURAN® Bell Jar, with aperture in neck is the article on this page. Luminix Health distributes DWK Life Sciences for laboratory use. It sits in Reaction vessels & jacketed vessels, inside Beakers & flasks, in Laborbedarf.
A reaction vessel is the flask a synthesis actually runs in, sometimes jacketed so a fluid can heat or cool the wall. The joints, the working volume and the jacket connections are the specification. It is not a storage bottle.
A beaker is an open working vessel: easy to pour, poor as a measure. An Erlenmeyer flask has a flat base and a conical wall so a liquid can be swirled without climbing out. A round-bottom flask is for heating under a condenser, because the heat meets a curved wall and the joint at the neck connects to the rest of the glassware. Borosilicate is the glass that survives the temperature change. These forms are listed under ISO laboratory glassware.
