Laboratory adapters are commonly used to connect and join different pieces of glassware. They are typically made from borosilicate glass, known for its excellent thermal resistance and chemical inertness. These types of lab glassware adapters come in various sizes and include different kinds such as standard joint adapters, reducing/enlarging adapters, expansion/contraction adapters, thermometer adapters, multiple neck adapters, vacuum adapters, and distillation adapters.
