Description
neoChoice round-bottom flask 50 ml with NS 29/32 ground joint is a single-neck borosilicate glass vessel designed for distillation, reflux, collection and related laboratory operations. The larger NS 29/32 joint provides a wide, standardised connection for condensers, still heads and adapters where higher vapour throughput or robust mechanical coupling is preferred. Nominal volume is 50 ml (0,05 l), ideal for small-batch synthesis, solvent work-up and sample concentration. Fabricated from borosilicate glass 3.3, the flask combines good chemical resistance with thermal stability for heating on mantles or baths. Offered in packs of 10 pieces from manufacturer neolab - Labor, the set supports parallel setups and stock replenishment in research, quality-control and teaching laboratories. Typical applications align with round-bottom, ground-joint, distillation and receiving flask duties. The spherical body promotes uniform heat distribution, while the single neck keeps assemblies compact and easy to clamp securely on a stand.
This article belongs on Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about neoChoice Rundkolben 50 ml, NS 29/32, 10 St./Pack
What is this article?
neoChoice Rundkolben 50 ml, NS 29/32, 10 St./Pack is the article on this page. Luminix Health distributes neolab 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.
