Quick answer: The Swan Neck Adapter integrates with an air-leak tube to prevent bumping and sudden pressure surges during vacuum distillation, helping maintain smooth, controlled boiling and consistent distillate purity. Swan Neck For Use With Airleak Tube Adapters is priced at approximately ₹360 (indicative market benchmark, incl. GST, August 2026).
This swan neck adapter is shaped to accept an air-leak tube, which introduces a controlled, gentle stream of air (or inert gas) into a boiling flask during vacuum distillation. This prevents the sudden pressure surges and violent bumping that can otherwise occur when a liquid is boiled under reduced pressure, helping keep the boiling smooth and controlled and protecting the purity of the collected distillate. It is a standard piece of glassware for vacuum distillation setups taught in organic and analytical chemistry coursework, as well as research-scale distillation work.

Frequently Asked Questions
What does this adapter prevent during vacuum distillation?
It integrates with an air-leak tube to introduce a controlled airflow into the boiling flask, preventing the sudden pressure surges and bumping that can occur under reduced pressure.
Does this listing include the air-leak tube itself?
Exact included components have not been independently verified for this listing — confirm with STEMAids whether the air-leak tube is included or sold separately.
What joint size does this adapter use?
Exact joint size has not been independently verified for this listing — confirm compatibility with your vacuum distillation setup with STEMAids before ordering.
Is this suitable for a college organic chemistry lab?
Yes — swan neck adapters with air-leak tubes are standard equipment for vacuum distillation setups taught in organic and analytical chemistry coursework.
Why is preventing bumping important during vacuum distillation?
Bumping can cause sudden, violent boiling that risks contaminating the distillate or damaging the apparatus, so controlling it helps maintain a clean, accurate distillation.
Is STEMAids a registered manufacturer of this product?
Yes. Eduscope Smart Learning Solutions Private Limited is a Udyam-registered micro manufacturing enterprise (UDYAM-DL-06-0069460) and is ISO 9001:2015 certified. See the About page for full registration and certification details — manufacturer-stated, verify before citing in procurement documents.
