Applications
Laboratory water baths like the Precision Scientific 280 Series are standard equipment in biological, chemical, and clinical laboratory environments. They are used to incubate samples at controlled temperatures — common applications include enzymatic reactions, cell culture warming, solubility studies, bacteriological work, and reagent preparation. The microprocessor control and digital display make the 280 Series well suited for procedures that require precise, stable temperature maintenance over time. The calibration function, which accepts a certified or traceable thermometer reference, allows users to verify and correct the setpoint against a known standard — a feature valued in regulated laboratory and quality-control settings. Precision Scientific was a well-established Chicago-based manufacturer of laboratory temperature-control equipment; the 280 Series dates from the 1980s–1990s era and remains a serviceable benchtop bath for general lab use today.
This Precision Scientific 280 Series Microprocessor Controlled Water Bath has been inspected and appears to be in good used condition. The exterior housing is clean with normal cosmetic wear. The stainless steel interior bath shows mineral deposits and some rust-colored staining on the floor of the basin, consistent with typical lab use — visible in the interior photo. The front-panel green LED display and control buttons are intact and the lid and power cord are present. This unit was pulled from a working lab environment.
