Description
The Across International Clear5 Short Path Distillation Kit is a professional 5-liter molecular distillation system designed for efficient purification and separation of heat-sensitive compounds. Featuring heavy-wall borosilicate glass and a vacuum-jacketed vapor pathway, this short path distillation kit minimizes heat loss while maximizing condensation efficiency.
The newly redesigned vacuum-jacketed distillation head features an expanded vapor channel and increased internal diameter, allowing for improved vapor flow and more efficient fractionation during distillation. This design helps prevent clogging while ensuring smooth and consistent operation.
Constructed from high-quality borosilicate glass 3.3, the Clear5 system delivers excellent chemical resistance, thermal stability, and durability for laboratory and research environments.
This kit includes the distillation head, 5L boiling flask, receiving flasks, distribution adapters, thermometer adapters, and laboratory support equipment, making it a complete solution for small-to-mid scale molecular distillation applications.
