Vacuum probe: new approach to the microbiological sampling of surfaces

W J Whitfield et al. Appl Microbiol. 1969 Jan.

Abstract

The need for a device to sample large areas that are lightly contaminated with microorganisms motivated the development of the vacuum probe. The intended use of the instrument is to sample clean surfaces in laminar flow clean rooms, but the device could be used for sampling surfaces in other clean environments. Such a device was designed, fabricated, and tested at Sandia Laboratories, Albuquerque, N.M. In these tests, the vacuum probe removed a mean of 89% and assayed a mean of 67% of bacterial spores, approximately 1 mum in length, settled on smooth surfaces which were free from viscous films.
