S4FR Refrigerated Floor Standing Centrifuges

The Thermo Scientific™ S4FR Refrigerated Centrifuge combines high-capacity performance with an environmentally conscious design, specifically engineered for space-saving floor-standing configurations. Coming standard with an easy-to-use keypad and high-contrast LCD display, the interface simplifies operation by providing detailed data on a wide range of operating parameters and processing status. At the heart of its sustainability is GreenCool™ Technology, utilizing a next-generation natural R290 refrigerant cooling system with a low Global Warming Potential (GWP) of 3 and zero ozone depletion.

This system provides stable cooling down to a -20°C temperature setpoint—achieving lower temperatures than previous models to ensure sample integrity—while complying with modern EU and US EPA F-gas regulations. The unit is manufactured in a certified zero-waste facility using 100% renewable electricity in Osterode am Harz, Germany, further supporting your lab's green initiatives.

Operational efficiency is enhanced by the Auto-Lock™ Rotor Exchange, a secure, ergonomic push-button system that allows users to quickly switch between 13 different rotor options in as little as three seconds without tools, providing full chamber access to minimize contamination risks and facilitate easy cleaning. For sample safety, the S4FR features SMARTSpin™ Imbalance Detection, which optimizes safety and improves separations by maximizing acceleration, braking, and residual load imbalance adjustments for each specific rotor and bucket option.

Whether processing large volumes of cell culture or high-throughput blood tubes, the modern industrial design—featuring an ergonomic height, compact footprint, and curved profile—ensures easy sample loading and unloading. The motorized lid latch enables a one-finger downward motion for the easiest possible closing and locking. The centrifuge also features standard lockable casters, making it easy to store, relocate, or clean within specialized laboratory and cleanroom environments (ISO Class 8 certified).
