3M™ Petrifilm™ Environmental Listeria Spreader, Pack of 2

The Petrifilm® Large Square Spreader is compatible with the Petrifilm Environmental Listeria Plates. Once the sample has been prepared, the top film is lifted from the Petrifilm Plate to expose the inoculation area and the diluted sample is added.

The technician places the film onto the sample and then uses the spreader to distribute the sample. The clear acrylic construction of the spreader allows the technician to ensure proper inoculum distribution.

• The design easily spreads inoculum over a uniform area.
• The spreader is reusable and does not contact the plating surface or sample.
• Clear acrylic material allows the technician to observe and control spread.
• Easy to use tool.
