4-Neck flask, 1000 ml, with 4 baffles is a robust multi-neck laboratory vessel intended for larger-scale synthesis, distillation and reaction setups that require efficient mixing and multiple simultaneous connections. Made from borosilicate glass 3.3, it features a centre neck NS 29/32, two side necks NS 29/32 and one side neck NS 14,5/23 angled at 7°. Four internal baffles promote turbulent flow, enhancing heat and mass transfer during agitation. A bottom drain valve adjustable from 0 to 10 mm enables controlled discharge without dismantling the apparatus. Offered as a single piece with a net weight of 0,450 kg, this flask from manufacturer Rettberg is designed for demanding laboratory environments. The multi-neck arrangement readily accepts condensers, dropping funnels, temperature probes and stirrers, while the inherent chemical resistance and thermal performance of borosilicate glass 3.3 ensure durability across repeated process cycles. Suitable for collection, reaction or distillation work where reliable ground-joint geometry and baffle-assisted mixing are essential.

Questions about 4-neck flask, 1000 ml, with 4 baffles, mn size 29, sn 2x size 29, 1x size 14,5,
What is this article?
4-neck flask, 1000 ml, with 4 baffles, mn size 29, sn 2x size 29, 1x size 14,5, is the article on this page. Luminix Health distributes Rettberg for laboratory use. It sits in Rondbodemkolven, inside Bekerglazen & kolven, in Labmateriaal.
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.
