Expansion Adapter – Socket 24/29 to Cone 14/23 (Borosilicate Glass)

The Expansion Adapter S 24/29 to C 14/23 is a high quality laboratory glassware component designed to connect jointed apparatus of different sizes safely and efficiently. Manufactured from premium 3.3 borosilicate glass, this adapter offers excellent resistance to heat, thermal shock, and chemical attack, making it suitable for demanding educational and laboratory environments.

This adapter features a 24/29 socket (S) and a 14/23 cone (C), allowing smaller jointed glassware to be securely connected to larger joint sockets. Precision‑ground joints ensure a tight, leak‑free seal, supporting reliable performance in distillation, reflux, and reaction assemblies commonly used in school science laboratories.

Durable, clear, and designed for repeated use, this expansion adapter adds flexibility to laboratory setups while maintaining safe and professional working conditions.
