Microbial Test, pack of 10 tests
Test your metalworking fluid’s contamination level easily. This test is specially designed for cutting fluids and other MWFs, providing a simple and reliable way to detect levels of bacteria, yeasts, and molds.
Its affordable price makes it possible to test fluids regularly. Fluid manufacturers and health authorities recommend testing contamination levels weekly.
How to use the tests
Measuring microbial contamination (bacteria, molds, and yeasts) is now very simple. Take the sample paddle from the tube and dip it into the fluid for about 10 seconds. If oil or other impurities are floating on the surface of the tank, stir them away before taking the sample.
After sampling, place the test in an environment of approximately 30 °C and incubate for at least 72 hours. If the temperature is lower (20–25 °C), extend the incubation time to at least 120 hours. Using an incubator provides more accurate and comparable results.
After incubation, use the comparison tables below to determine the contamination level.
Bacteria
The magnitude of bacteria, where the number represents the exponent of 10. For example, 6 equals 10⁶, corresponding to 1,000,000 bacteria/ml.
Yeasts
The magnitude of yeasts, where the number represents the exponent of 10. For example, 6 equals 10⁶, corresponding to 1,000,000 bacteria/ml.
Molds
The magnitude of molds, where the number represents the following: 0 = no contamination, 1 = light contamination, 2 = moderate contamination, and 3 = heavy contamination.
