Beschreibung
Two-neck adapter with two parallel necks, joint size 29/32, is a ground-joint laboratory fitting designed for larger multi-neck reaction assemblies. It is made from borosilicate glass LBG 3.3, offering the chemical durability and thermal stability needed for synthesis, reflux and distillation work. The two parallel necks share the same NS 29/32 joint standard, enabling secure attachment of condensers, addition funnels, stirrer guides or gas lines alongside the main vessel connection. This geometry keeps accessories aligned and reduces stress on the joints during setup. Delivered as one piece with a net weight of 0,120 kg, the adapter from manufacturer Labbox integrates into existing LBG 3.3 and other compatible borosilicate ground-joint systems. It is well suited to preparative organic chemistry, scale-up trials and teaching laboratories that require robust, reusable glassware for parallel reagent handling or inert-atmosphere operations without custom glassblowing.
