Abstract:

The valve sealing system for a reagent package includes an annular cylindrical gasket seated in a channel formed in the package. A rocker valve on the package pivots relative to the annular cylindrical gasket which surrounds an opening to the chamber of the reagent package. The annular channel includes a radially inner peripheral channel sidewall, a radially outer peripheral channel sidewall, and a bottom portion. An inclined peripheral wall portion of the channel intersects one of the channel sidewalls at an obtuse angle and the bottom portion of the channel. When the rocker valve is in a valve closed position it engages the annular cylindrical gasket to provide a substantially leak-tight seal.

Abstract:

The fluid circuit for a hematology analyzer includes a block-like plastic member with passageways for fluid, and a reaction chamber recess that communicates with one or more of the fluid passageways. A detachable metallic heat transfer cover member is positioned across the reaction chamber recess to close the reaction chamber recess and establish a confined reaction chamber. A heater is placed in conductive contact with the metallic heat transfer cover member to heat the cover member and thereby conduct heat to the reaction chamber. The metallic heat transfer cover member is detachably secured to the block-like plastic member and can thus be removed and replaced as needed.
