Adapter Claisen Heads

[table id=584 /]

The GISCOM Adapter Claisen Head is a precision-engineered glass connector used to create dual-neck access in distillation, reflux, and synthesis setups. It allows simultaneous attachment of condensers, thermometers, dropping funnels, or other glassware, enhancing efficiency in multi-step reactions. Designed for robust and high-accuracy laboratory applications, the Claisen Head is essential for workflows requiring controlled heating, vapor handling, and parallel operations.
