Description
BOLA two-neck ground joint round-bottom flask, 500 ml, is a transparent, pore-free laboratory vessel fabricated from perfluoroalkoxy alkane (PFA) with one central ground joint NS 29/32 and one side neck NS 29/32. The spherical body offers a nominal volume of 0,5 l, an overall height of 177 mm and a ball diameter of 107 mm, providing a stable geometry for heating baths, stands and jointed assemblies. PFA construction delivers a smooth, non-porous inner surface suited to chemically demanding media while remaining fully compatible with standard NS ground-joint accessories. The dual-neck layout supports simultaneous connection of condensers, dropping funnels, probes or inert-gas lines during distillation, reaction work-up and receiving duties. This flask from manufacturer Bohlender is supplied as a single piece and fits typical laboratory workflows that call for polymer alternatives to glass round-bottom flasks. Net weight is 0,1996 kg. It is appropriate for use as a round-bottom, ground-joint, distillation or collecting flask wherever reliable NS mating and chemical inertness are required.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about BOLA Round Bottom Flasks with Two Ground Joint Necks, 500 ml 1 Center socket siz
What is this article?
BOLA Round Bottom Flasks with Two Ground Joint Necks, 500 ml 1 Center socket siz is the article on this page. Luminix Health distributes Bohlender 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.
