INSIGHTS on Centrifuges

Centrifuges work on the principle of sedimentation facilitated by an apparent angular force that draws components of a rotating sample away from the center of rotation. Although centrifugation theory is straightforward, its engineering literature is voluminous due to the number of industries and research operations that depend on the operation.

Purchasing and Caring for a Lab Essential

What’s important here is that centrifugation efficiency is proportional to the spinning radius and to the square of the angular velocity (radians per second, generally referred to as speed in revolutions per minute, rpm).

Thus, for a given rpm value a centrifuge with a 12-inch radius will be twice as efficient as one with a six-inch radius, and for a constant radius a device spinning at 1,000 rpm is four times as effective as one rotating at 500 rpm.

Help your Colleagues

Plenty of discussions are happening on LabWrench all the time. We have many questions come in daily from users that are seeking advice from fellow users and lab professionals on LabWrench. Can you help any of these users find the answers they are looking for?

Varian SpectrAA 220FS - Error Message
I can't find an answer to this anywhere. Any help is appreciated. I have a Varian SpectrAA 220fs and am running a graphite furnace on it. It will run my samples but stop short of finishing them and give me an error message that reads "low source energy". Any idea what this means? Advise this member.

PerkinElmer EnVision - Communication issue
I have an EnVision 2101 that I am trying to connect to a new install of the Wallac software. For some reason the software does not see the system. Are there specific CAN settings for these units that I need to change for the software to see the unit? Advise this member.

Stirling Ultracold SU780UE - Ultra Cold Helium Engine
Seems that Stirling Ultra Cold has cornered the internet with all of their tests. Unfortunately I can't seem to find anywhere and/or a factory that could tell me what it would cost if the helium engine failed and needed to be replaced. Does anyone have information about that? Advise this member.
