GOBI9D — Laboratory Hotplate, Aluminium Surface, Digital Control 40×60 cm
OVERVIEW
The GOBI series is COLO aluminium-surface laboratory hotplate line designed for precise, uniform heating of media, glassware and reaction vessels.
High heating power, intelligent PID temperature control and a chemically resistant special coating make these hotplates a robust choice for demanding sample preparation workflows.
The GOBI9D model is the largest digital hotplate in the series, featuring a 400×600 mm aluminium surface, up to 350 °C working temperature and a maximum load of 40 kg.
The digital microprocessor PID controller provides stable temperature control, with integrated self-diagnostics, error indication and a timing function with time delay.
Short heating times, excellent plate temperature uniformity and a clear LED display for setting and reading parameters help ensure reproducible results in routine and advanced laboratory applications.
