Histology laboratories in hospitals and elsewhere require significant amounts of manual work. These labs also have to contend with rising workloads and increasing work complexity. Current labor vacancy rates are about 10-12%. and it has been predicted that the retirement rate in these work environments will be about 18-36% within the next 5 years. Within these labs, microscope slide cleaning in preparation for scanning and / or pathologist review is often a tedious task. Typically, the slide cleaning process requires manual application of cleaning fluids and wiping of slides with lens paper to remove dust, fingerprints, specks, and the like. Leaving these contaminants on the slide can lead to out of focus image sections which increases the risk of obscuring diagnostically relevant information. Thus, there is a need for improvement in this field.

To invent a method for allowing spray arm rotation speed to be regulated accurately.SOLUTION: A regulator includes a weight on a pivot and a fluid jet, the weight having a curved surface to produce a variable angle corner spray nozzle depending on the weight angle. Centrifugal force created during rotation of a spray arm pushes the weight outward, and increases as the spray arm rotation speed increases. The liquid jet is located out from a pivot point and pushes the weight inward. The pushing force of the liquid jet is maximum when the weight is most inward and minimum when the weight is most outward. The regulator stabilizes the arm speed at a specific speed, independent from center pivot friction and the spray arm nozzle's orientation tolerance. The arm speed stabilizes when centrifugal force on the weight is equal to the pushing force at a fluid jet port.SELECTED DRAWING: Figure 2
