Description
Round-bottom flask 3000 ml with three necks is a large multi-neck laboratory flask for distillation, synthesis and collection applications. It is fitted with one centre neck and two side necks, all carrying NS 29/32 ground joints; the side necks are inclined at 20° to simplify simultaneous connection of condensers, addition funnels or sensors. Made from clear borosilicate glass 3.3, the vessel offers strong chemical resistance and reliable thermal performance during heating and cooling cycles. With a nominal volume of 3 l and a net weight of 0,735 kg, the flask provides ample capacity for preparative work, solvent recovery and multi-component reaction setups. Supplied as one piece from manufacturer Witeg, this three-neck round-bottom flask is compatible with standard ground-joint glassware and is suitable for atmospheric or moderate-vacuum operations that demand precise joint geometry and good visibility of the contents.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Round bottom flask 3000 ml three necks CN + two SN
What is this article?
Round bottom flask 3000 ml three necks CN + two SN is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Round-bottom flasks, inside Beakers & flasks, in Labware.
A round-bottom flask is the heating flask of a distillation or a reflux. The curved wall takes the heat, and the ground neck connects to a still head or a condenser. The joint size, not only the volume, has to match the rest of the set.
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.
