Dipslide vs Petrifilm vs Laboratory Analysis: Which Microbial Test Should You Use?
A cooling tower, a metalworking fluid sump, and a boiler feedwater line all have the same underlying question: how many bacteria are in there right now, and does someone need to act today? Three tools answer that question at very different speeds, costs, and levels of precision — the dipslide, Petrifilm, and full laboratory analysis. […]
How to Measure Bacteria in Metalcutting Coolant — and When to Act
A metalcutting coolant that smells like rotten eggs on Monday morning is already in serious trouble. The hydrogen sulphide odour is produced by anaerobic bacteria that have been multiplying in the sump over the weekend, without agitation, in the absence of oxygen. By the time the smell is obvious, bacterial counts are in the billions […]
