Thermo WX Ultra80 Floor Ultracentrifuge

Location: 8143 MRB3

$12.50 / Reservation*

*Note: The fee of $12.50 / Reservation is effective as of September 29, 2016.

A reservation in C.O.R.E.S. is required for this device and billing is done automatically through the system. Although C.O.R.E.S. says that you will be billed "Per Hour", you will only be billed for one $12.50 charge per reservation.

Please ask the Equipment Manager for a quick training before using this centrifuge for the first time.

The VBI Equipment Core does not stock tubes for labs to use for ultracentrifugation. It is the responsibility of the lab to provide these consumables.

Online Rotor Calculation Tool

There are several online tools for converting rotations-per-minute (rpm) to relative-centrifugal-force (rcf or "x g") or vice versa. These are extremely useful when you find a protocol where you know the parameters for centrifugation using a specific rotor but don't have access to that rotor. In this case, you will need to utilize a tool which can help you "reverse calculate" these parameters. Science Gateway has a wide variety of rotor choices from which you can select to help you with this (see instructions and example below).

Go to the link Science Gateway Rotor Calculator

  • Select your rotor in the dropdown (i.e., Beckman, Sorvall, or Other)
  • Type in your "x g" into the rcf box and hit the rpm button to calculate the rotations-per-minute needed to obtain that g force
  • Sometimes published protocols are incomplete and the authors only publish the rpm for their rotor. You can always do the calculation in reverse by putting this in the rpm box and hit the rcf button to calculate the g force they obtained. Then, you would go to the previous step to recalculate the parameters for your particular rotor.
