Abstract
The present invention relates to the field of tissue processing, particularly, to the treatment of fluids used in tissue processing. In one embodiment the present invention provides for treating a tissue processing fluid comprising first processing fluid comprising a first processing fluid and a second contaminating fluid, by: gradually varying the pressure of the fluid from an initial pressure level to a first pressure level such that the fluid remains below a vaporizing point of the second contaminating fluid and, heating the fluid to at least a vaporizing temperature of the second contaminating fluid. In another embodiment, the present invention removes the second contaminating fluid from the fluid by varying at least one of the pressure and temperature of the fluid so as to allow the second contaminating fluid to vaporize. Alternatively, an embodiment of the present invention interleaves the step of removing with one or more tissue processing protocol steps. In a preferred embodiment, the invention relates to the treatment of infiltrating materials, particularly in their liquid form in a histological tissue sample processor capable of Xylene free operation.
