Description
Round-bottom flask PFA, NS 29/32, 500 ml is a single-neck laboratory vessel made from perfluoroalkoxyalkane (PFA) with a nominal volume of 500 ml and a standard ground joint of NS 29/32. PFA provides outstanding chemical inertness and thermal stability, making the flask suitable for demanding digestion, distillation, concentration and sample-preparation work with aggressive acids, bases and organic solvents. The round-bottom geometry promotes uniform heat distribution and efficient mixing on heating mantles, oil baths or rotary evaporators, while the NS 29/32 joint ensures compatibility with matching stoppers, condensers and adapters. With one neck and a gross weight of 0,21 kg, the flask remains easy to handle during routine bench-scale operations. Produced by manufacturer Vitlab, this PFA round-bottom flask serves research, analytical and industrial laboratories that require non-contaminating, highly resistant reaction or collection vessels. The 0,5 l working capacity balances useful volume with manageable size for everyday laboratory use. Supplied as one piece, it integrates readily into existing glassware and fluoropolymer apparatus sets used in chemical synthesis and sample work-up.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Round bottom flask, PFA, 500 ml
What is this article?
Round bottom flask, PFA, 500 ml is the article on this page. Luminix Health distributes Vitlab 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.
