Ultracentrifuge and rotors

Biocenter Oulu, University of Oulu, seeks an ultracentrifuge and associated rotors to separate biological macromolecules (mainly proteins), extracellular vesicles (EVs), lipid nano particles (LNP), and other (bio)nanoparticles. The system will be part of the Proteomics and protein analysis core facility infrastructure of Biocenter Oulu. The core facility has an open access policy, and the instrumentation and software must be easy to use and maintain. The device must include a user interface to control the operation. The device must be well suited to an academic multi-user environment. The centrifuge must be suitable for preparative ultracentrifugation. The centrifuge must be able to reach a maximum speed of at least 80 000 rpms. The tender must include a fixed angle rotor with g values of at least 230 000 g, a fixed angle rotor with g values of at least 300 000 g, and a swinging bucket rotor with at least 250 000 g. The system (device and rotors) is expected to come with detailed documentation of all features. The contracting entity has a maximum sum of 95000€ (excluding VAT) available for the procurement and cannot accept tenders exceeding this amount. The procurement is partially funded by the European Regional Development Funds (ERDF), BioParts project (A81573). The contracting entity suspended the previous procurement procedure related to this procurement on 3 July 2026.
