Precision Concentric Ring Electric Steaming Baths

Precision Concentric Ring Steaming Baths are designed to gently warm samples, make concentrates, and melt solids such as agar. Available in both 4 opening and 8 opening models, they accommodate various sizes of glassware and evaporating dishes, including round bottom flasks. Flange-formed stainless steel rings nest smoothly and become progressively larger as each concentric ring is removed. Copper clad immersion heaters provide bath temperatures up to 100° C. These baths require hardwire installation by a qualified electrician and need to be hooked up to a continuous water source.
