Thermo Scientific Sorvall ST4F Plus-MD Centrifuge

The Thermo Scientific Sorvall ST4F Plus-MD Centrifuge is a high-capacity and versatile floor model centrifuge that offers consistent performance and is ideal for routine applications. This unit comes standard with an easy-to-use keypad and high contrast LCD display. The intuitive controls simplify operation and provide detailed information on a wide range of operating parameters and processing status for optimal performance. The modern industrial design incorporated into this centrifuge supports continuous improvement in rotor loading ergonomics, user safety and current needed certifications. A motorized lid latch is featured, enabling one finger downward motions for easiest closing and locking of the centrifuge lid.

This centrifuge also utilizes Thermo Scientific’s Auto-Lock™ III Rotor System, which is a secure locking system that allows easy push-button installation and exchange of rotors. This system saves time when switching between applications and provides easy access to the rotor chamber offering quick cleaning, a healthier working environment, and longer unit life. Also featured is Thermo Scientific’s SMARTSpin™ Technology, which is an advanced rotor management system that maximizes acceleration, braking, and residual load imbalance for each rotor and bucket option, optimizing safety and improving separations. Overall, the ST4F Plus-MD Centrifuge provides faster processing of more samples with a high capacity-to-footprint ratio and simple programming interface, plus the flexibility to run most tubes and bottles on one centrifuge. The included TX-1000 Swing Bucket Rotor reaches a maximum speed of 3,800 RPM and a maximum RCF of 3,374 x g.

All of our equipment is in excellent condition and will be fully tested to perform at factory specifications before being shipped.

Please confirm this rotor meets your application needs and request a different rotor, if necessary. Available rotors can be found in our Rotor Compatibility Guide.
