  • MPN: 1820-055
  • Filter Paper Type: Glass fiber
  • Condition: Apparently new, seemingly full open box containing unused filter circles. Since the cellophane wrapper is gone, and it would be counterproductive to dirty the filters by counting them, we don’t know if the original quantity of 100 circles is present. As you can see in the photographs, which depict the detailed condition of the actual item for sale (cropped but not otherwise altered), the box certainly looks full! It has to my knowledge only been opened to take these photographs. We conservatively estimate from the photos that at least 90 circles are included in this item.
  • Modified Item: No
  • Intended Use/Discipline: Biological Laboratory, Chemistry Laboratory
  • Country/Region of Manufacture: United Kingdom
