Info

• patented trumpet tip piston gradually compresses thin bands of particles into vertical columns prior to capture. • uv scan capability with optional pharmacia uvm ii attachment. • internet programmability: the software installed in an instrument you purchase today is upgradable by simply downloading a new version into the fractionator directly from your computer using a supplied serial cable. Gradient Station This newly developed hybrid instrument performs both gradient forming and fractionating. The performance of its two elements, the Piston Gradient Fractinator and the Gradient Master is identical to the separate instruments.

BH4 Fractionator Researchers working with deadly viruses at the NIH in Bethesda and Ft. Detrick MD asked us to develop a gradient fractionator that would be easily transported and fit inside the BSC4 hood. The standard Gradient Station or Piston Fractionator are too heavy and too large to fit these requirements, so we set out to reduce the height of the device and shave off some of its weight. The result is a fractionator that, at 9.5 kg, weights half as much as the standard one and fits easily into most BioHazard hoods. It has all the same features as the standard fractionator and uses the same tube holders as well. The maximum height allowed was 65 cm, but the new design comes in at 63 cm. The danger of emitting dangerous aerosols during fractionation has been eliminated by removing the air pump, but it can be included it if desired. 6-Piston Fractionator As the inventor of the piston fractionator, I was fortunate to be able to construct the fractionator of my dreams. My laboratory at the University of New Brunswick was studying phage T4 morphogenesis and routinely ran 6 to 12 gradients every day. In some cases we harvested individual bands we could see with the light scattering visualization system, while in others we
