3M™ Petrifilm™ High-Sensitivity Plate Spreader 6481, 2 per box

Spreader used to distribute the sample evenly for 3M™ Petrifilm™ High-Sensitivity Coliform Count Plates.

This spreader is compatible with the following 3M™ Petrifilm™ Plates: Aerobic Count Plates, Coliform Count Plates, Rapid Coliform Count Plates, Enterobacteriaceae Count Plates, E. coli/Coliform Count Plates, Aqua Coliform Count Plates and Aqua Heterotrophic Count Plates. Once the sample has been prepared, the top film is lifted from the 3M Petrifilm Plate to expose the inoculation area and the diluted sample is added. The technician places the film onto the sample then uses the spreader to distribute the sample. The clear acrylic construction of the spreader allows the technician to ensure proper inoculum distribution.
