250 mL Regular Double-Wall Jacketed Beaker, 70 mm Inner Diameter (CAT#: STEM-BC-3583-ZJF)

This 250 mL double-wall jacketed beaker is designed for controlled laboratory sample temperatures. BORO3.3 high-borosilicate glass provides good thermal stability and corrosion resistance. Its transparent walls allow continuous visual monitoring of the sample. The annular space between the inner and outer cups carries heating or cooling fluid. Two barbed ports allow connection to an external circulating bath. The scale is located on the outside of the inner cup to help prevent wear. Four-ridge nozzle construction improves tubing retention during circulation. A rounded rim and flat base provide smooth handling and stable placement.
