ABSTRACT:
This invention provides a liquid separating composition containing as a base material a liquid polymer of hydrocarbon or derivatives thereof having a viscosity ranging from 100 to 20,000 CP at 20.degree. C., suitable amounts of additives for adjusting the specific gravity and viscosity of the composition and a network former for imparting a thixotropic property to the composition. This invention also provides an apparatus for applying a liquid separating composition, comprising a vessel filled with a liquid separating composition, and a cannula fixed to the vessel, for piercing into a rubber cap of a liquid container.
The liquid separating composition is transferred to the liquid container by centrifuging the apparatus connected to the liquid container.
