Description
Attachment DN 100 with centre neck NS 29/32, three angled side necks NS 29/32 and one straight side neck NS 14/23 is a versatile multi-neck head for distillation and reaction work on DN 100 flat-flange vessels. Manufactured from borosilicate glass 3.3, it provides one centre neck NS 29/32, three side necks angled at 15° with NS 29/32 joints, and one straight side neck NS 14/23. The larger NS 29/32 side ports accommodate bulkier condensers, stirrer guides or dropping funnels, while the smaller NS 14/23 port remains available for thermometers or gas inlets. Net weight is 0,478 kg. This configuration from manufacturer Witeg supports complex multi-component setups in organic synthesis, fractional distillation and process development. Borosilicate glass 3.3 ensures high chemical resistance and good thermal-shock performance under typical laboratory heating and cooling cycles. Supplied as a single piece, the attachment mates directly with standard DN 100 flat-ground lids and complementary ground-joint glassware, offering a practical solution for research and teaching laboratories that require flexible multi-port access on larger flange systems.

Questions about Lid DN 100 CN ST 29/32 SN ST 29/32 SN ST 14/23
What is this article?
Lid DN 100 CN ST 29/32 SN ST 29/32 SN ST 14/23 is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Distillation heads, adapters & columns, inside Distillation & extraction glassware, in Labware.
A still head, an adapter or a column is the glass between the boiling flask and the condenser. A Vigreux or packed column gives the vapour a surface so a closer-boiling mixture can separate. The joint sizes at both ends have to match the flask and the condenser.
Distillation separates liquids by boiling point. A condenser turns the vapour back into liquid: Liebig, coil and cold-finger shapes differ in how much cooling surface they offer. A still head and a column sit between the flask and the condenser. A Soxhlet extractor washes a solid again and again with the same solvent. Ground joints have a standard size, and the joint, not the flask, is what has to match. The pieces are indexed under ISO laboratory glassware.
