Glass Joints & Adapters
Lab glass joints are crucial accessories for laboratory glassware. They provide a range of benefits to assist with laboratory processes and safety. At Thomas Scientific, we stock an extensive range of glassware that is customizable and adaptable to suit your specific requirements. Choose between glass u-tubes, short path distillation heads, snyder columns, and much more. High-quality glass adapters offer a smooth non-porous surface and carry additional features such as heat resistance and chemical compatibility, which makes them suitable for a range of laboratory applications. Benefit from leak-free and customizable connections with glassware pieces. Transparent glass joints enable Scientists to observe reactions and processes within the glassware to provide real-time monitoring of experiments. Glass accessories include nmr tube cleaner to assist with keeping all glassware clean and contamination free.
