Description
Four-neck flask with straight side necks NS 29/32, 10 l is a large multi-neck round-bottom vessel designed for laboratory distillation, reaction and collection procedures. Offering a capacity of 10 000 ml, the flask is fitted with a central ground joint NS 45/40 and four straight side necks finished to NS 29/32. These standardised joints allow simultaneous connection of condensers, dropping funnels, thermometers, stirrer guides and gas inlets, supporting complex experimental setups. The round-bottom geometry promotes even heating and effective mixing of reaction mixtures. Available as a single piece from manufacturer Witeg, this four-neck flask is well suited to organic synthesis, solvent recovery and preparative chemistry where multiple access ports are required. The ground joints ensure reliable assembly with common laboratory glassware components. Its generous working volume makes the flask particularly valuable for scale-up experiments and pilot-scale processes in research and production laboratories. Compatible with standard NS joint accessories, it provides a versatile platform for multi-step reactions under controlled conditions.

Questions about Four-neck flask, 10,000 ml, with straigh
What is this article?
Four-neck flask, 10,000 ml, with straigh 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.
