Columns Acc. To Hempel
Product Code : EL-CC-10061
Lab Glassware Manufacturer manufactures and exports the Columns Acc. To Hempel from its Ambala, Haryana facility, supplying school, college and research laboratories in India as well as export buyers that have recently included institutions in Vietnam, Thailand and the Philippines — part of a wider base of enquiries from across Southeast Asia.
Quick answer: This is a plain (non-jacketed) glass column fitting made to work with Hempel-type fractionating column assemblies, terminating in an NS (interchangeable) socket at one end and an NS cone at the other so it can be connected directly into a distillation or column train. It is manufactured in Borosilicate Glass 3.3 for chemical and thermal resistance.

| Joint type | NS socket at one end, NS cone at the other |
| Jacket | None — plain (unjacketed) column body |
| Material | Borosilicate Glass 3.3 |
Fitting Into a Distillation or Column Train
The NS socket-and-cone combination is an interchangeable ground-glass joint, so this column section connects directly to other NS-jointed glassware (a Hempel-type fractionating column, a receiver adapter, or a distillation head) without adapters, provided the joint sizes match. Leaving the body unjacketed keeps the piece simpler and more economical than a vacuum-jacketed column, which suits routine teaching and general laboratory distillation work rather than applications that specifically call for jacket-insulated separation.
Frequently Asked Questions
What does an NS socket and NS cone joint mean?
NS (interchangeable/standard taper) joints are ground-glass fittings sized to a standard taper so that a socket on one piece of glassware seals directly against a matching cone on another, without grease-fit adapters, as long as the NS sizes match.
Why is this column unjacketed rather than vacuum-jacketed?
An unjacketed column body is simpler to manufacture and lower cost than a jacketed one, and is suited to routine distillation and teaching setups where the extra thermal insulation of a jacketed column is not specifically required.
Why is Borosilicate Glass 3.3 used for this column?
Borosilicate Glass 3.3 has a low coefficient of thermal expansion and good chemical resistance, which allows the column to withstand the heating and solvent contact involved in distillation and fractionation work.
