Orbital Shaker PSU-20i

The stable PSU-20i orbital shaker is a multifunctional shaker for many routine laboratory tasks. Its wide selection of additional platforms and various mounting options makes it highly versatile.

The PSU-20i offers three types of motion: orbital, reciprocal or vibrating. These can be performed separately, pairwise and sequentially in repeated cycles.

The shaker runs silently and reliably. Thanks to the direct drive system and the brushless motor with up to 35,000 hours of service life, it offers stable continuous mixing for up to seven days.

Multi Functional Orbital Shaker

Designed for applications in both small specialized laboratories and large multidisciplinary laboratories.

The shaker is designed for operation in cold rooms, incubators (except CO₂ incubators) and closed laboratories. Suitable for an ambient temperature of +4°C to +40°C in a non-condensing atmosphere and a maximum relative humidity of 80% at temperatures up to 31°C, decreasing linearly to 50% relative humidity at 40°C.

A highlight is the multi-level platform. This makes it possible to accommodate a large number of different microplates, Petri dishes and other low containers.
