Rotor Calculations

Rotor Calculations for RCF

Relative centrifugal force (RCF) is converted to revolutions per minute (RPM) using the following formula. The radius, r, is equal to the distance in millimeters between the axis of rotation and the bottom of the centrifuge tube. The value calculated will be g (RCF) maximum

Here are some of the rotors presently available for purchase from GMI.
The first five are Sorvall rotors, the latter are Beckman ultra rotors.   We
will be adding the complete carbon fiber line and the Beckman line of
high speed and ultracentrifuge rotors as soon as we are able.   We
will add more rotors as soon as we can to the calculator.

To calculate the Unknown quantities, enter the known value and select it's
"Compute from ..." button. If we've missed a rotor, or if you just bought one,
email the Rotor guy at GMI the specific rotor details.
Provide: (Rotor name, k factor, Max_speed, R_min, R_max,).

We are pleased to offer the rewards of 40 years of aerospace engineering representing the most sensible and safe alternative to the standard aluminum and titanium rotors. Carbon fiber rotors are light-years ahead of metals in strength, weight, and durability. Carbon fiber rotors are half the weight of aluminum rotors making them both safer and easier to handle. Carbon fiber rotors also are easier on the centrifuge, reducing wear on the drive system. Carbon Fiber rotors are available for low-speed, high-speed and ultra-speed centrifuges. Many rotors are available in two forms: Standard and Enhanced Liquid Containment (ELC) versions. The Standard version has a straight top and lid. The ELC version contains a special lid and curved annulus at the top of the rotor. ELC models are designed to contain fluid leaks and eliminate imbalance problems and spindle damage that may result from fluid leaks. These rotors work seamlessly in the most popular centrifuges from major manufacturers. Carbon fiber rotors can be autoclaved and most are backed by a LIFETIME WARRANTY. Why would you ever buy an old fashioned metal rotor again? Step into the 21st century
