Product Details

How much bacteria grows in refrigerated milk? What happens if milk stands out for a day or even for a few hours? Students test refrigerated milk, boiled milk and room-temperature milk to determine and compare their relative bacterial conditions. Students use the resazurin color reaction to demonstrate the relative amounts of bacteria in the various milk samples. Kit materials include the test tubes, powdered milk and the resazurin test solution.

Complete for 30 students working in pairs. Super Value Kit is complete for five classes of 30 students working in pairs.
