Beckman Coulter Microfuge 20 Centrifuge
The Beckman Coulter Microfuge 20 Centrifuge is a high-performance bench-top device designed for a range of laboratory applications. It offers a maximum speed of 15,000 RPM and a maximum RCF of 20,627 x g, with a maximum capacity of up to 36 x 1.5/2.0 ml tubes. This centrifuge is ideal for nucleic acid and protein preparations, routine processing tasks such as sample preparation, pelleting, extractions, purifications, concentrations, phase separations, and receptor binding, as well as rapid sedimentation of protein precipitates, particulates, and cell debris. Featuring a microprocessor-controlled system, the Microfuge 20 ensures precise operation with a brushless three-phase drive and selectable acceleration/deceleration rates. Safety features include an electromechanical door-locking mechanism, a steel barrier for operator protection, and an overspeed monitoring system with a magnetic sensor. The centrifuge’s rubber feet are designed to reduce rotation during rotor mishaps. Additionally, the system continuously monitors sensor signals to ensure functionality, displaying error messages in case of malfunctions. The compact and versatile Microfuge 20 provides the flexibility required for diverse separation protocols. The included FA241.5P Fixed Angle Rotor reaches a maximum speed of 15,000 RPM and a maximum RCF of 20,627 x g.All of our equipment is in excellent condition and will be fully tested to perform at factory specifications before being shipped.
Please confirm this rotor meets your application needs and request a different rotor, if necessary. Available rotors can be found in our Rotor Compatibility Guide.
The Beckman Coulter Microfuge 20 Centrifuge includes:
- > FA241.5P Fixed Angle Rotor
- > NIST Centrifuge Calibration and Preventative Maintenance Report
- > Power Cord
- > Operator's Manual
- > Full 180 Day Parts and Labor Warranty
