Used Eppendorf Refrigerated Centrifuges

Yes, an Eppendorf refrigerated centrifuge can precool the rotor and chamber before processing samples. Some Eppendorf refrigerated centrifuge models let you activate the refrigeration system independently of the centrifuge motor, so the chamber and rotor can reach your target temperature before a run starts.

This feature matters most for temperature-sensitive samples like proteins, enzymes or cell lysates, where brief exposure to ambient temperatures can affect integrity. Precooling times vary based on your target temperature, room conditions and the rotor's thermal mass.

Bench space and ventilation clearance requirements for an Eppendorf refrigerated centrifuge vary by model, and the specific dimensions are defined in each unit's operator manual or spec sheet. As a general guideline, Eppendorf recommends adequate clearance on the sides and rear of the unit to allow proper airflow for the refrigeration system. Restricted airflow can affect temperature regulation. A level, sturdy bench rated for the instrument's weight is also recommended. For exact footprint dimensions and clearance requirements, consult the specifications for your specific unit before installation.

Safe cleaning solutions for an Eppendorf centrifuge and its rotor generally include mild laboratory detergents, 70% ethanol and isopropanol for routine decontamination. For rotors, avoid strong acids, strong and weak alkalis, halogenated solvents, phenol, concentrated saline solutions and heavy-metal-ion solutions, as these can affect rotor integrity over time. Wipe the chamber interior with a damp cloth and mild detergent, and allow the rotor and chamber to dry fully before the next run.

Whether you can run microcentrifuge tubes, conical tubes, blood collection tubes and microplates in the same centrifuge depends on rotor compatibility for your specific model. Many Eppendorf refrigerated centrifuges accept multiple rotor types and, with the right adapters, can handle a wide range of vessel formats. 

Each vessel format typically requires its own compatible rotor or adapter configuration, so running different formats in the same centrifuge means swapping setups between runs rather than loading all formats at once. Before you switch between vessel formats, confirm that the rotor and adapter combination is rated for the speed and g-force your application requires.
