Description
Sulfonation flask 100 ml with centre neck NS 29/32 and four side necks NS 14/23 is a multi-neck laboratory reaction vessel intended for synthetic and preparative work. The 100 ml working volume is paired with one central ground joint NS 29/32 and four lateral ground joints NS 14/23, allowing simultaneous attachment of condensers, dropping funnels, thermometers or gas inlets during sulfonation and related multi-component reactions. Pack size is one piece; net and gross weight are each 0,16 kg. Manufactured by Witeg in Germany (Baden-Württemberg), the flask follows standard conical joint dimensions that integrate with common laboratory glassware trains. The four side necks keep reagent addition, temperature control and gas handling accessible around the main centre-neck path, reducing the need to reconfigure a single-neck setup mid-reaction. This compact multi-neck geometry suits research, process-development and teaching laboratories that require controlled multi-port access in a small working volume. Joint sizes remain fully compatible with standard NS 29/32 and NS 14/23 accessories used throughout organic and inorganic synthesis workflows.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about sulfonation flask 100ml NS29/32 4x14/23
What is this article?
sulfonation flask 100ml NS29/32 4x14/23 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.
