5810722004: Medical Adapter for 5.0 mL and 15 mL
The Eppendorf 5810722004 is a cup adapter designed for use with A-4-81 and S-4x500 rotors when processing Eppendorf Tubes® 5.0 mL and 15 mL conical tubes. It is intended for common medical applications such as blood sample preparation, urine clarification, phase separation or precipitation of biomolecules prior to analysis. The conical housing ensures that the tube is held securely during rotation and contributes to uniform sedimentation, which is key to reproducible results in hospital and clinical analysis laboratories.
Capacity and Dimensions Adapted to Clinical Workflows
Each adapter offers 12 cups; a 4-cup rotor therefore provides 48 positions in a single run, facilitating the management of routine sample series. The maximum tube diameter is 17 mm, which is compatible with the 5.0 mL and 15 mL tubes targeted. The maximum cuvette height is 121 mm, and remains 121 mm with the lid, which simplifies use when a cup lid is required. These values allow standard containers to be inserted while maintaining the necessary margin for balancing and secure closure.
Rotor Performance and Integration into the Workstation
When mounted on the rotors mentioned above, the adapter achieves a centrifugation radius of 173 mm and a maximum RCF of 3,100 × g, enabling fast and clean separations for biological matrices. The conical shape of the housings contributes to the mechanical stability of the assembly during rotation. Aerosol caps are available as an option, which are useful when handling potentially hazardous samples: the adapter can therefore be integrated into a centrifugation chain that complies with current biosafety requirements.
