Fisher Scientific Water Bath Model 80 Heated Circulating Bath 5x9x6 Tub

The Fisher Scientific Water Bath Model 80 is a benchtop heated circulating water bath designed for temperature-controlled laboratory applications. It combines a built-in heater element with a motor-driven circulation pump to maintain a uniform temperature throughout the bath. The unit features a front-panel dial controller (scale 1–8) with an On/Off toggle switch and indicator light, and a rear panel with dedicated Inlet and Outlet hose barb ports, a motor speed control, and a circuit breaker switch.

Applications

Heated circulating water baths like the Fisher Model 80 are standard equipment in chemistry, biology, and materials science laboratories. They are used to incubate samples at controlled temperatures, warm reagents, support enzymatic reactions, run condensers, and maintain steady thermal conditions for titrations and extractions. The circulation pump keeps the bath temperature uniform throughout, making these units well suited for work requiring consistent heat distribution. Fisher Scientific water baths of this era — a design dating from the mid-20th century and common in industrial and university labs through the 1970s and 1980s — were widely used in pharmaceutical, chemical, and aerospace research environments. Surplus units like this one are still put to work in teaching labs, small research setups, and shops needing a simple, reliable heated bath at a low cost.
