Orbital laboratory shaker PSU-20i

vibratingdigitalfor laboratory

Overview
PSU-20i is a multifunctional laboratory shaker providing three motion types: orbital, reciprocal and vibrating. Motions can be applied separately, in pairs or sequentially in repetitive cycles. The unit is designed for small specialized labs as well as large multidisciplinary facilities and is suited to biopharmaceutical and biomedical research workflows.

Performance and reliability
The shaker operates quietly and reliably thanks to a direct-drive system and a brushless motor with a rated lifetime up to 35,000 working hours. Direct drive and brushless motor enable continuous mixing up to 7 days and support extended continuous use beyond two years under normal laboratory conditions.
