Beschrijving
DURAN® flat flange bell jar with opening in neck is a precision glass vessel engineered for vacuum experiments and work under reduced pressure. It features an NS 34/35 ground joint and a diameter of 185 mm, allowing combination with a vacuum experiment plate to examine reaction behaviour in the rough- and fine-vacuum range. Manufactured from borosilicate glass 3.3, the jar offers high chemical resistance and mechanical strength. The standardised ground joint delivers a tight seal, while the neck opening permits connection of additional apparatus. A permanently fired white print marking remains legible throughout the service life. Supplied as one piece with a net weight of 2,4 kg, this bell jar from manufacturer Duran/DWK Life Sciences is suited to vacuum-chamber trials, under-pressure demonstrations and educational or research applications that require controlled atmospheres. Optical clarity of the glass enables continuous observation of internal processes, and the robust construction maintains integrity under vacuum conditions typical of laboratory practice.

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 Labmateriaal.
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.
