In shared labs, core facillities, and biotech or pharma environments, one centrifuge often serves many users and applications. Centrifuge 5811 R is designed for exactly this setting. With up to 3L capacity and speeds up to 20,9136 x g (14,000 rpm), it covers routine centrifugation of tubes, bottles, and plates in one benchtop instrument — from cell pellets and bacteria to nucleic acid and protein preparations or clinical samples.
The cooling system uses propane (R290) with a low global warming potential (GWP = 3), delivering high energy efficiency and meeting evolving environmental standards, while providing reliable temperature control from -9°C to +40°C. ECO shutoff and an aerodynamic bucket design further support energy-conscious lab operation.
Transitioning from a Centrifuge 5810 R setup is straightforward, as existing swing-bucket and fixed-angle rotors remain compatible with Centrifuge 5811 R, recucing additional hardware investments and simplifying the upgrade path. Combined with a strong price-performance ratio, this makes the Centrifuge 5811 R a practical allrounder for labs that route many experiments through one centrifugation hub.
Versatility for your discovery
Centrifuge 5811 R offers up to 3L capacity — for example 4 x 750mL or 28 x 50mL / 56 x 15mL in a single run — making it suitable for medium to high sample throughput. A portfolio of 15 rotors and numerous adapters accommodate standard tubes, bottles, flasks, and plates, while mixed bucket loading enables simultaneous centrifugation of different vessel types. Maximum speeds of up to 20,913 x g (14,000 rpm) support fast, reproducible results.
The instrument can be used with vessels from 0.2mL to 750mL, providing one solution for many applications. It remains compatible with the rotors of Centrifuge 5810/5810 R, so existing rotor assets can continue to be used.
Ergonomics and ease of use
An intuitive keypad and dedicated program key provide direct access to up to 35 user-defined programs, saving time at every run. The low access height supports comfortable loading and unloading, while the Soft-Touch Lid allows easy closing. The Eppendorf QuickLock® rotor lids and caps enable safe operation. Quiet operation supports a focused working environment, and the lightweight rotor design simplifies handling.
Safety for your samples and users
Centrifuge 5811 R supports safe operation through automatic rotor recognition and imbalance detection. Aerosol-tight rotor lids and caps are tested and verified to help protect users and samples when working with hazardous or sensitive materials. Reliable refrigeration performance safeguards temperature-sensitive samples throughout the run.
Sustainability for your discovery
The cooling system of Centrifuge 5811 R uses propane (R290) as a refrigerant, with a low GWP of 3 that supports the sustainability targets of modern laboratories. ECO shut-off modes and the aerodynamic bucket design help reduce energy consumption. Rotors made from recyclable aluminum support responsible use of resources.
