Designed with durability, reliability, and safety in mind, the Spectra/Por Magnetic Stirrer has a precision, high-speed control system—ranging from 60 - 1500 RPM—with a continuously smooth revolution pattern. The technically advanced PCB (Printed Circuit Board) eliminates electrical overload and regulates energy distribution. A bearing-type motor maintains gentle revolution over the lifetime of the equipment. The Spectra/Por Magnetic Stirrer features a heat-resistant, anti-corrosive aluminum body with a high-quality powder coating. A ceramic coated stainless steel top plate provides excellent chemical resistance, especially against strong acids and bases.
