Description
Round-bottom flask 2000 ml with two necks is a multi-neck laboratory flask for distillation, synthesis and collection work. It combines a centre neck NS 29/32 with a straight side neck NS 29/32, giving reliable ground-joint connections for condensers, dropping funnels, gas inlets or temperature probes. The vessel is made from clear borosilicate glass 3.3, which provides high chemical resistance and good thermal shock performance for routine heating and cooling cycles. With a nominal volume of 2 l, the round-bottom geometry supports even heat distribution when used with heating mantles or oil baths. This two-neck design from manufacturer Witeg is well suited to preparative organic chemistry, solvent recovery and multi-step reactions where simultaneous addition and reflux or distillation are required. Categories of use include round-bottom flasks, ground-joint flasks, distillation flasks and receiving flasks. Supplied as one piece with a net weight of 0,536 kg, it is a practical choice for research, teaching and quality-control laboratories needing durable multi-neck glassware in the 2000 ml range.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Round bottom flask 2000 ml two necks CN + SN
What is this article?
Round bottom flask 2000 ml two necks CN + 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.
