The Thermo Scientific Multifuge 1S Centrifuge is a 1.6 liter capacity non-refrigerated centrifuge with a wide assortment of rotors available. This centrifuge reaches speeds up to 15,000 RPM with maximum RCF of 24,652 x g. The Multifuge 1S allows for easy high volume processing with automatic rotor recognition and quiet operation. With higher RCFs and great flexibility, the Multifuge 1S is ideal for microbiology, pharmaceutical, clinical testing, biotechnology, and general lab use. This rotor reaches a maximum speed of 10,250 RPM.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 Thermo Scientific Multifuge 1S Centrifuge includes:
- > 75002006 Rotor
- > NIST Centrifuge Calibration and Preventative Maintenance Report
- > Power Cord
- > Operator's Manual
- > Full 180 Day Parts and Labor Warranty
