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.
