TL;DR Summary
Query - does a centrifuge spinning to create X g-force, mounted on a platform that is rotating the the same rpm's the opposite direction, negate the g-force? Or does the g-force stay the same but from an outside perspective the centrifuge appears stationary?

Welcome to PF.

What do you think the answer is and why? Do you know how to write the equation of motion of an object in the centrifuge as seen in a rest frame in the laboratory?

Also, can you show us a sketch or picture of the arrangement you are asking about? You can use the "Attach files" link below the Edit window to add PDF or JPEG images to your posts.

As @berkeman says, a drawing will help.

It sounds like you have two concentric cages, with the outer one rotating and the inner one not, Is that correct? If so, does that give you any ideas?

I have only one clarifying question for the OP:
From the vantage point of an observer outside the centrifuge contraption, how fast (if at all) is the occupant rotating?

I have no real clue what the OP is asking about lol, not the best statement that describes accurately the situation. The best I can make of it is that we have some object that is rotating around some point in a lab, say clockwise, and the whole lab is rotating (around the same point or different point?) in an opposite direction counterclockwise.
