Dust sampler for black foreign matter, 100 sheets, DS-CLEAR, 1 bag (100 sheets)

This adhesive sheet can be used to sample large fallen particles over 300 μm in size that are difficult to suck up using air samplers. Sampling will be carried out over a 24-hour period and visually inspected for any falling debris. It comes with a protective film that can be reapplied, making it possible to store foreign objects after sampling. This is an improved version of the DS-20, which makes it easier to remove air bubbles from protective film.
