The THERMOstar is a high-performance microplate incubator and orbital shaker for up to four microplates. It can be used for any enzyme or cell-based assay requiring uniform and controlled incubation and/or effective mixing. Microprocessor-controlled heating plates above and below the microplates ensure outstanding temperature accuracy and uniformity across the plate, providing constant temperature up to 56 °C with < 0.6 °C variation. Temperature, shaking speed, and incubation time are easy programmable via the keypad and all status parameters are displayed on the LCD in real time.
