Thermo Scientific Sorvall X4 Pro 75009905

Ideal for a wide range of general purpose applications including cell culture, bioproduction, blood separation and microbiology amongst others, the new Sorvall X4 Pro research centrifuge series feature a convenient 4 litre capacity and are available in both ventilated and refrigerated units.

The research models offer a wider range of rotors and accessories than their routine counterparts, including high speed carbon fibre rotors from the Fiberlite range. Featuring an exceptionally clear display panel and 99 pre-set programs as opposed to the 6 featured by the routine models, the research series of centrifuges are perfect for a busy research environment.

Other additional features developed to assist in a research environment include the facility for setting the time of the run from when the rotor reaches speed, the ability to monitor and control the sample temperature as opposed to the bowl temperature of the centrifuge, and a password protection option to prevent un-authorised interruptions to sample runs.


  • High Capacity: Process up to 40 x 50 ml conical tubes (40% more) in a swinging bucket rotor, or up to 14 x 50 ml (100% more) in fixed angle configuration, for significantly increased capacity over competitive models in the same bench space.

  • Unmatched Versatility: The broadest range of rotors and adapters available in the industry, with a minimum of 16 rotor configurations, enables your lab to meet all processing needs.

  • Fiberlite Compatibility: Achieve higher G-force and faster speeds, and ensure exceptional security and efficiency with our robust, corrosion-free design with a Thermo Scientific Fiberlite rotor

  • Industry-Leading Energy Efficiency: Experience up to 40% energy consumption savings * on industry standard protocols, such as blood separation or conical tubes processing.

*based on internal benchmark

  • Compact, Ergonomic Design: Compact dimensions, ergonomic height and curved design ensure comfortable and space-efficient workspace.

  • Advanced Programmable Controls: Improve sample protection with detailed operation information to maximize run performance. Ensure temperature accuracy and control between -10° and +40°C, supported by a double temperature control system which displays the air temperature in the chamber, as well as the sample temperature, for ultimate control of the sample temperature during the run.

Features innovative Thermo Scientific patented solutions

Auto-Lock® III Rotor System

Secure locking system delivers:

  • Installation and exchange of rotors with just the push of a button for quick switch between applications

  • Easy chamber access enables cleaning convenience, reducing contamination risk and leading to improved research and a healthier working environment

Auto Lock Brochure

Hybrid Lid Latch

  • Improve closure time and reduce wear with our highly reliable, motorized lid latch system – combining the advantages of mechanical and electromechanical systems

  • One finger downward motion for easiest closing and locking – even on tall benches

  • Optional automatic lid opening at end of run for rapid retrieval of samples

  • Password protection option for sample security, preventing unwanted removal of temperature-sensitive samples

ClickSeal® Bucket Sealing System

Innovative biocontainment solution provides:

  • Simple operation for all laboratory users, eliminating screw caps and complicated clips

  • Glove-friendly, one-handed open/close capability

  • Biocontainment certification by CAMR* in Porton Down, UK

  • Polyetherimide (PEI) sealing covers with high chemical resistance and excellent thermal properties

*CAMR is now incorporated within the UK Health Protection Agency (HPA)

SMARTSpin® Technology

  • Advanced rotor management system optimises acceleration, braking, temperature control and residual load imbalance for smooth runs and reproducible separations
