  • Intended Use/Discipline: Chemistry Laboratory
  • Country/Region of Manufacture: United Kingdom
  • Condition: Leftover unused filters, stored in a research laboratory drawer. Given that location there is some light wear and superficial staining, especially in one corner on the bottom of the box. It seems to contain almost all of the original 100 circles; we conservatively estimate 90 remain, since to keep them clean we did not pull out and count the filters. Photographs depict the detailed condition of the actual item for sale; they have been cropped but not otherwise altered.
