Abstract
Nanofibrils are nano-sized fibrils made from protein isolates. To make the nanofibrils that protein isolate solution was heated in a water bath at 80 oC while stirring for more 16 h. This nanofibril formation process requires a water bath that can heat and stir protein isolates. So far there have been a lot of stirrers and water baths, but those that can heat and stir together simultaneously are very limited. Therefore it is necessary to design a water bath that can be paired with a stirrer so that it can heat and stir continuously. The portable water bath designed includes the chamber, heater, thermostat and control panel. This water bath works in a temperature range of 50oC -120oC. Water bath can be paired with heater.
