NOTE Samplers for Dip Testing or Swab Testing in Breweries. W. M. Ingledew and J. Diane Burton, Agricultural Microbiology Section, Department of Dairy and Food Science, University of Saskatchewan, Saskatoon, Canada S7N 0W0.. J. Am. Soc. Brew. Chem. 39:0039, 1981.

Experiments with Millipore Yeast and Mold and Total Count™ samplers have demonstrated that recovery of typical brewery bacteria and yeasts from suspensions is poorer when samplers are used than when traditional membrane filtration is used. Based on these data, such samplers, at least in their present mode, cannot be recommended for use in the brewery.
