31 Loveton Circle, Sparks, MD We make the analytical reagents as well as many of the plastic components found in our test kits, such as the comparators that house the color standards, the reagent bottles, and the carrying cases. We even print many of our instructions in-house. Our first preference is always to do it ourselves, at our 60,000-sq.-ft. facility just north of Baltimore, Maryland. That way we have tighter control over quality and availability, plus we can effect changes more rapidly.  Sparks Business Center lot: mud today, magnificent tomorrow Our new corporate headquarters will be built on 27 acres in the Sparks Business Center, a mile from Taylor's present location and conveniently located on the Interstate 83 corridor. The plan for the campus-style operations center takes its inspiration from Thomas Jefferson's design for the University of Virginia. Ultimately the site will support 300,000 sq. ft. of new construction.
