STLE University Webinar – Emerging Issues in MWF Microbiology: Biofilm Control
Fred Passman will be presenting a webinar on Monday 20 July 2011 from 1:00 PM until 2:00 PM (Eastern Daylight Time). During the webinar he’ll be discussing key concepts that industry stakholders must understand in order to effectively control biofilm accumulation in MWF systems.

READ MOREASTM APPROVES NEW FUEL AND FUEL-ASSOCIATED WATER TEST METHOD
An ASTM Standard Test Method, based on LuminUltra Technologies’, has just been approved as ASTM D 7687, Method for the Measurement of Cellular Adenosine Triphosphate in Fuel, Fuel/Water Mixtures and Fuel-Associated Water with Sample Concentration by Filtration. Unlike Previous ATP test methods, the new Method has been demonstrated to not be affected by the Chemical interferences that have limited the overall usefulness of more…
READ MOREASTM APPROVES TWO NEW MICROBIOLOGICAL TEST METHODS FOR METALWORKING FLUIDS
In April 2009, ASTM approved two new Standard Test Methods. E 2657, Method for Determination of Endotoxin Concentration in Water-Miscible Metalworking Fluids, replaces an older Method: E 2250. E 2694, Method for Measurement of Adenosine Triphosphate in Water-Miscible Metalworking Fluids, is a new tool for measuring microbial biomass in MWF in less than 5-minutes….
Both new methods are available for…
READ MOREFOR ATP IN FUELS, LUBRICANTS AND METALWORKING FLUIDS SHOW GREAT PROMISE
Recently approved ASTM D 7463 (ATP in Fuel) works great for rapidly determining biomass in conventional fuels. However, D7463 depends on an aqueous extraction step in which the extraction reagent pulls microbes out of the fuel sample. This step makes it impossible to use the method for determining ATP in fuels that retain water (for example ethanol-blended gasolines and some biodiesel fuels), or from high water-content…
READ MOREASTM DEVELOPS NEW METHOD FOR TESTING BIOMASS IN FUELS AND FUEL-ASSOCIATED WATER
Historical test methods for detecting microbial contamination in fuels (for example ASTM D6974 ) depended on the ability of microbes to form colonies on specific growth media. These methods were time consuming and typically required a 2-30 day incubation period before final results were obtained. ATP (adenosine triphosphate) is a molecule that is present in all bacteria, fungi, plant and animal cells. Hence, it…
