The unique design of the AccuPoint® Advanced Access sampler offers greater sample precision and consistency. Unlike traditional swabs, the sampler utilizes a flocculated sample tip to extract ATP fromthe work surface. The pad surface and sampling technique allow different users more consisten results than other flexible swabs. The very small tip picks up ATP along sample areas and the very thin stick allows you to reach those hard to areas such as small pipes. 100 per box in four foil packets of 25 samplers each.
