Description
The Across International Clear2 Short Path Distillation Kit is a compact 2L molecular distillation system designed for efficient purification and separation of heat-sensitive compounds in laboratory and research environments. Built with heavy-wall borosilicate glass and vacuum-jacketed vapor pathways, this short path distillation system minimizes heat loss while maximizing vapor condensation efficiency.
The newly redesigned vacuum-jacketed distillation head features a larger vapor channel and increased internal diameter, allowing for improved vapor flow and more efficient fractionation while preventing clogging during operation.
Constructed from high-quality borosilicate glass 3.3, the Clear2 system is engineered for durability, chemical resistance, and consistent laboratory performance.
This kit includes the distillation head, boiling flask, receiving flasks, distribution adapters, thermometer adapters, and laboratory support accessories, making it an excellent solution for small-scale molecular distillation and research applications.
