Quick answer: A Reduction Adapter connects a larger ground glass socket to a smaller cone size, letting mismatched pieces of glassware fit together airtight within a distillation or synthesis assembly. Reduction Adapters, Reducing Interchangeable Joints is priced at approximately ₹345 (indicative market benchmark, incl. GST, August 2026).
This reduction adapter bridges a larger interchangeable socket on one end to a smaller cone on the other, so pieces of glassware with different standard joint sizes can still be connected without leaks. This comes up often in a working lab where equipment has been acquired over time or from different sources and doesn’t share a single joint size throughout. Made from borosilicate glass, it maintains chemical resistance and thermal stability while preserving the airtight, vacuum-capable connection a distillation or synthesis setup needs, making it a practical addition to a college or research chemistry laboratory’s glassware collection.
