ETH - Fast-rotating centrifuge
The FRC was built in our workshop according to the theoretical calculations of Silver (Silver, I. The dynamics of a discrete geotropic sensor subject to rotation-induced gravity compensation. J. Theoret. Biol. 61, 353 (1976)). It consists of a metallic tube that is rotated around its longitudinal axis at a defined rotation speed. Samples are sealed in Teflon tubes with screw caps. Five tubes containing 2 ml of culture can be placed in one metal tube of the FRC. Up to 4 metal tubes can be rotated at the same time. A special device allows the injection of liquid in one culture tube/metal tube during rotation.
The FRC is located in a room, which can be thermo stated at 37±1° C.
Rotation speed: adjustable.
For animal cells the usual rotation speed is 90 r.p.m. resulting in a maximum centrifugal force of 1.8%g
Dimensions of Teflon culture tubes: 13 cm long with inner diameter of 4.5 mm.
The laboratories of the Space Biology Group are equipped with 2 laminar flow benches, CO2 incubator, space bioreactor, several centrifuges, autoclaves, fluorescence microscope with photo device, cell counter, gas chromatograph. The offices – one especially for guests – are equipped with PC’s and Macintosh all connected to the Internet.
More information especially on the space bioreactor is available on our web page: www.spacebiol.ethz.ch
