The AVAIN LABS® Adapter Reduction is a high-quality laboratory glass adapter designed for connecting glassware with non-similar joint sizes in scientific, research, and industrial laboratory applications. This precision-engineered adapter features a larger lower joint and a smaller outer joint, enabling secure and leak-proof connections between glass apparatus of different standard joint sizes.
Manufactured from premium laboratory-grade glass, the adapter ensures excellent chemical resistance, thermal stability, and durability, making it suitable for a wide range of distillation, reflux, extraction, and analytical procedures. The adapter is produced in compliance with DIN 12257 standards, ensuring dimensional accuracy and compatibility with standard laboratory glassware. ASTM E-676 compliant versions are also available upon request.
Ideal for use in distillation assemblies, reflux systems, chemical synthesis setups, extraction processes, analytical laboratories, research applications, and scientific glassware connections where different joint sizes must be interconnected.
