Abstract: A biological fluid sampling transfer device adapted to receive a multi-component blood sample is disclosed. After collecting the blood sample, the biological fluid sampling transfer device is able to separate a plasma portion from a cellular portion. After separation, the biological fluid sampling transfer device is able to transfer the plasma portion of the blood sample to a point-of-care testing device. The biological fluid sampling transfer device also provides a closed sampling and transfer system that reduces the exposure of a blood sample and provides fast mixing of a blood sample with a sample stabilizer. The biological fluid sampling transfer device is engageable with a blood testing device for closed transfer of a portion of the plasma portion from the biological fluid sampling transfer device to the blood testing device. The blood testing device is adapted to receive the plasma portion to analyze the blood sample and obtain test results.

Abstract: A process for the formation of a plated through-hole printed circuit board comprising treating a circuit board base material as follows:1. condition with an oxidant solution;2(A). contact with a copper etchant that etches copper and neutralizes oxidant residues on the surface to be plated; and2(B). contact with a conditioner that conditions the board surface for enhanced catalyst adsorption; or2(A). contact with a neutralizer for oxidant residues that neutralizes said residues and conditions the board surface for enhanced catalyst adsorption; and2(B). contact with a copper etchant; and3. catalyze the board; and4. plate electroless metal onto catalyzed surfaces from a plating solution containing a source of halide ions in a concentration of at least 0.1 moles per liter of solution.The process is characterized by the absence of a step of acceleration and contains fewer processing steps than prior art processes.
