Stainless Steel Constant-Temperature Cup, 4.5 L (CAT#: STEM-BC-3561-ZJF)

This 4.5 L constant-temperature cup is intended for larger laboratory samples and reaction volumes. It uses a double-wall structure consisting of inner and outer stainless-steel vessels. The enclosed space between the walls serves as a circulating thermal jacket. Heating or cooling medium enters through the lower inlet connection. It flows around the inner vessel before leaving through the upper outlet. The circulation pattern supports even temperature transfer across the reaction chamber. The cup can be connected to an external heating or cooling circulator. Its 201 stainless-steel construction provides strength, good heat conduction, moderate chemical resistance, and reusable service.
