This is a brand name or equal solicitation, requiring the centrifuge to be capable of countertop installation, refrigerated operation (maintaining at least 10 degrees C), and compatibility with both fixed angle and swinging bucket rotors. The package must include a swinging bucket rotor compatible with 15mL and 50mL tubes, along with adapters for various tube and bottle sizes up to 1000 mL. The rotor must achieve a relative centrifugal force (RCF) of at least 4000 x g. A 5-year limited warranty is also required. The delivery location is the USGS Research Lab in Boulder, Colorado.
