Glassware laboratory adapter JSDD series

interfacevacuum distillationmultiple

Overview
The Double Socket Joint is a precision glass adapter with female sockets at both ends. Manufactured from Borosilicate 3.3 glass, it provides a leak-proof, vacuum-tight connection between two glass cones in laboratory assemblies in accordance with DIN standards. The double-socket geometry facilitates smooth transitions between apparatus parts and is intended for use in distillation, extraction and reaction setups. Precision-ground to a 1:10 taper for universal compatibility with DIN/ISO compliant glassware. High thermal shock resistance and autoclavable for repeated sterilization cycles.

Usage and maintenance
Apply a light film of vacuum grease or use a PTFE sleeve on male cones to ensure vacuum-tight seals and to reduce the risk of joint seizing. Clean with a soft cylindrical brush and mild laboratory detergent; remove all grease residues to avoid contamination. Take care when cleaning the internal ground surface. Joints are typically unprinted; size markings may be etched in the glass.
