Contact Plates: Total Bacteria, Total Coliform, & Yeast/Mold
Fast and simple, these contact plates require no swabbing or evening. Simply remove the lid, press the raised medium against the surface being tested, replace the lid and allow to incubate. The number of colonies can be counted using the 10mm grid pattern on the bottom of the plates. These plates are ideal for measuring surface contamination and to test the effectiveness of cleaning procedures. All need to be refrigerated. Plates are shipped 2-day air. A ship date is required.
