Increase Your Productivity With Prior's 8 Slide Stage
	The H138 features: Travel 230 mm x 71 mm (9" x 3") Repeatability to + 1.0 micron Step size (resolution) of the stage is from 0.1 micron to 5.0 microns, depending on the controller configuration Stages customized to any microscope or mount Stage insert for eight slides

You can increase your specimen handling speed and efficiency with the Prior Model H138.This stage allows you to work more productively by loading up to eight 11' x 3" specimenslides on one stage and processing them together. Sample holders can be released quicklyand easily interchanged to increase processing speed. You can unload and load slides whileothers are running. The H138 even allows you to scan long specimens that won't fit on otherstages.The H138 is one of a full range of motorized stepper stages from Prior Scientificadaptable to virtually any microscope or optical system. The H138 lowers the processingcost per specimen by allowing users, for example medical technicians, to increaseproductivity and improve throughput through faster scanning.

Prior stages have a well-deserved reputation for quality and repeatability. They are manufactured using the highest quality components: crossed roller ways, zero backlash recirculatedball screws, X and Y limit switches, two high precision stepper motors - even a tough scratchresistant coating. They are available with standard and custom sample holders to suit theuser's application and requirements.
