Description
Thread adapter Type 77 is a polypropylene laboratory connector that converts an S50 female thread to a GL45 male thread. This compact fitting bridges two widely used bottle and vessel standards, allowing solvent reservoirs, waste containers and laboratory glassware to be linked without improvised couplings. Made from polypropylene (PP), the adapter offers solid chemical resistance for routine aqueous and many organic media encountered in analytical and preparative work. The Type 77 design from manufacturer SCAT is intended for HPLC waste lines, solvent supply bottles and general fluid-handling setups where S50 and GL45 interfaces must be joined securely. Supplied as a single piece, it integrates quickly into existing bottle-cap and tubing systems and helps maintain a clean, leak-resistant connection path. Its straightforward geometry supports repeated assembly and disassembly in busy laboratory environments, making it a practical accessory for chromatography, sample preparation and solvent management applications that rely on standardised laboratory threads.

Questions about Thread adapter, Type 77
What is this article?
Thread adapter, Type 77 is the article on this page. Luminix Health distributes SCAT for laboratory use. It sits in Hose connectors, adapters & fittings, inside Tubing, hoses & fittings, in Matériel de laboratoire.
A hose connector or adapter joins two lines, or steps one bore down to another. The barb diameter has to match the tube, and the thread has to match the stopcock or the bottle. Most leaks are a mismatch here, not a hole in the tube.
Tubing is how a liquid or a gas moves between two vessels without being poured. Silicone stays flexible and survives repeated autoclaving. PTFE resists almost every solvent and is stiff. PVC is the ordinary flexible line for water and for mild aqueous work. The fitting, not the tube, is what usually leaks: the barb, the thread and the stopcock have to match the tube bore. Glass and plastic apparatus around these lines is indexed under ISO laboratory ware.
