Yeast and Fungi are less common than bacteria and are one hundred times larger than bacteria and, therefore, only 10,000 yeasts will attack the chemical additives in the oil or cutting fluid, as much as 1,000,000 bacteria.
They are more resistant to biocide attack than bacteria and it is necessary that the biocide used in the oil will kill these as well as bacteria. Tektrak is able to supply suitable Biocide additives if required.
Ease of use and a wide range of applications make the Tektrak Dip Slide range the ideal answer for service engineers and busy laboratories where speed and repeatability are primary requirements.
