Description
Sulfonation flask 2500 ml NS 71/51 with four side necks NS 29/32 is a multi-neck laboratory flask designed for reactions that need several concurrent connections. It provides a nominal capacity of 2500 ml and features a wide central main ground joint NS 71/51 together with four lateral ground joints sized NS 29/32. The large main neck accommodates bulkier fittings, stirrer assemblies or larger condensers, while the four side necks allow simultaneous attachment of dropping funnels, gas inlets, thermometers or additional reagents. Standardised ground joints guarantee compatibility with everyday laboratory glassware. Available as a single unit from manufacturer Witeg, the flask has a net weight of 1,415 kg and is well suited to preparative synthesis, process development and multi-port reaction work in research and production laboratories. The combination of a generous main joint and four side ports supports flexible experimental layouts where controlled access to the reaction mixture is essential. This configuration is especially useful for sulfonation and related multi-reagent procedures that demand reliable, interchangeable ground-joint connections and substantial working volume.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about sulfonation flask 2500ml NS71/51 4x29/32
What is this article?
sulfonation flask 2500ml NS71/51 4x29/32 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.
