Abstract: A method of cleaning a pharmaceutical cell that can be carried out onsite in a pharmacy. In particular, the method can be used to clean a pharmaceutical super cell. The method includes placing the cell in a resealable container; adding a wash solution to the resealable container; sealing the resealable container; shaking the sealed container; pouring the wash solution out of the resealable container; and rinsing the cell by repeating the preceding steps using a rinse solution in place of the wash solution. The wash solution may include soap, alcohol, and/or a surfactant. The rinse solution may include deionized water and/or isopropyl alcohol, for example.

Abstract: A solder paste comprises a lead-free solder powder, a flux and an active additive in the flux. The active additive comprises a material that scavenges metal oxide from molten solder, is a stable liquid at reflow soldering temperature, and has the ability to assimilate oxide of at least one metal in the solder. A preferred active additive is dimer acid present in the range of from 0.5 to 2.5% percent by weight of the paste. Sound joint are obtained when the paste is used in a reflow soldering process wherein the peak reflow temperature is preferably less than 245° C.
