Cole-Parmer 04644-10 Digital Hot Plate Stirrer 120V 876W I/O Port Lab

Cole-Parmer 04644-10 Digital Hot Plate Stirrer 120V 876W I/O Port Lab

The Cole-Parmer 04644-10 is a benchtop digital hot plate stirrer from the 04644 Series, combining programmable heating and magnetic stirring in a single compact instrument. It features a digital LED display and a full numeric keypad for direct entry of target temperatures, stirrer speeds, and timer programs — a step up from the analog dial controls found on basic hot plate stirrers. The ceramic heating plate sits atop a sturdy blue-finished steel chassis.

Applications

The Cole-Parmer 04644 Series Digital Hot Plate Stirrer is used in chemistry, biology, and materials science laboratories for heating and mixing liquid samples simultaneously. The digital keypad and programmable timer make it well suited for protocols that require precise temperature setpoints or timed heating sequences — common in dissolution testing, sample preparation, buffer preparation, and chemical synthesis. The external temperature probe input allows closed-loop temperature control using a direct-immersion probe rather than relying solely on plate surface temperature, which is important when the actual sample temperature matters. The rear I/O port supports connection to a computer or data logger for automated control and data recording, making the 04644-10 a good fit for regulated lab environments where process documentation is required. These instruments were a standard fixture in academic and industrial labs from the late 1980s through the 2000s and remain in everyday service in laboratories that rely on straightforward, programmable benchtop heating and stirring.
