Bellco 7765-56065 SciEra 4-Place Precision Magnetic Stirrer 0-80 RPM Benchtop

The Bellco SciEra 7765-56065 is a 4-place precision magnetic stirrer designed for simultaneous stirring of up to four vessels on a single benchtop unit. Manufactured by Bellco Glass Inc. of Vineland, NJ, it provides variable-speed magnetic drive from 0 to 80 RPM via a front-panel speed control knob with a digital RPM readout. The unit includes a motion alarm system with a Motion Fail indicator, remote jack, and selectable horn alert for unattended operation monitoring.

Applications

The Bellco SciEra series of multi-place magnetic stirrers is used in cell culture, fermentation, and biochemistry laboratories where several spinner flasks, roller bottles, or beakers must be stirred simultaneously at low, controlled speeds. The 0–80 RPM range is well suited to sensitive biological applications such as hybridoma cell culture, suspension cell growth in spinner flasks, and gentle mixing of reagents where high-shear impeller stirring would damage cells or denature proteins. Bellco Glass has been a standard supplier for biological laboratory glassware and stirring equipment since the mid-twentieth century, and the SciEra line was widely adopted in academic, pharmaceutical, and biotech research settings from the 1980s onward. The motion alarm system allows unattended overnight runs — the unit can sound an alert or signal a remote device if stirring stops unexpectedly, which is important for time-sensitive culture work. The serial/analog interface and battery back-up provisions reflect the instrument-grade design intended for integration into monitored lab environments.
