Abstract
The invention relates to centrifuge apparatus of a type which is typically, although not necessarily exclusively, for use in counter current chromatography in which substances are caused to partition between two phases in a column typically in the form of a helix or spiral. The apparatus includes leads which connect the inlet and outlet conduits to a column which is moved by the apparatus and in accordance with the invention the leads are constrained within a sheath which includes a lubricant to allow lubrication of the same while the apparatus is in use and thereby increase the longevity of the apparatus. The opposing ends of the leads can also be constrained in terms of movement with, at one end of the leads being fully constrained and the opposing end the leads being constrained in terms of rotational movement.
Claims32
A centrifuge apparatus, said apparatus comprising:
- a shaft on which at least one column is mounted for planetary rotation about the shaft, the at least one column having an inlet and an outlet connected to respective inlet and outlet leads for communication to respective inlet and outlet conduits;
- and
- wherein between the at least one column and the inlet and outlet conduits, the inlet and/outlet leads are at least partially located within a tubular sheath having an end adjacent the column and an end adjacent the shaft, the tubular sheath containing a lubricant therein to allow hydrodynamic lubrication between the inlet and outlet leads and the sheath.

A unit, said unit comprising:
- inlet and outlet leads and a sheath through which the same pass and are enclosed thereby;
- said unit provided to be connected to centrifuge apparatus at opposing ends of the sheath;
- and
- wherein said sheath includes therein a lubricant, said sheath sealed at said opposing ends to retain the lubricant within said sheath.
