Food Protection Trends - November 2009 - 814

Industry Products including polymerase chain reaction (PCR) assays, tableted reagents and optimized media to detect Salmonella, Listeria species, Listeria monocytogenes, E. coli O157:H7, Enterobacter sakazakii, Campylobacter, Staphylococcus aureus, Vibrio, and yeast and mold. With certifications and regulatory approvals in the Americas, Asia and Europe, the BAX® system is recognized globally as one of the most advanced pathogen testing systems available to food companies. DuPont Qualicon 800.863.6842 Wilmington, DE www2.dupont.com The new Advanced patentpending flow control mechanics and electronics provide the smoothest, most accurate, and precise flow across the largest flow range. The new EZ Pro™ Software functions like a PC and contains an advanced methods architecture for preprogrammed quick-start or advanced methods templates. A new easy-to-use GUI on an advanced color display allows alpha/ numeric reporting capability and advanced connectivity at the touch of the screen. This unit also provides maximum versatility of configuration and application. It can handle flow rates from picoliter to 220 ml/min with the highest accuracy, precision and smoothness of flow. The PHD ULTRA™ can control remote units 30 ft away, accomodates 2 to 10 syringes for multi-channel or larger reservoir capacities, and contains advanced, preprogrammed operational modes. With the push of a button, alternate between autofill continuous-flow, pulsatile, bolus, concentration mode, daisy chain, gradients and flow programming modes. The functional balance of these features makes the PHD ULTRA™ the ultimate problem solver for your lab or work place in MS, drug infusion, nanofluidics, electro-spinning, aerosol generation, reaction chamber dosing and more. Solve your most demanding fluidics applications with PHD ULTRA™ fluidics from Harvard Apparatus. Harvard Apparatus 800.272.2775 Holliston, MA www.harvardapparatus.com Strategic Diagnostics Awarded Patent for Use of Bacteriophages in Mircrobiological Assays and Processes S Harvard Apparatus New Smooth, Accurate and Precise Syringe Pump from Harvard Apparatus H arvard Apparatus has introduced the new PHD ULTRA™ Syringe Pump. The PHD ULTRA sets a new performance standard in syringe pumps for smooth, accurate and precise flow. Harvard Apparatus introduced the first commercial syringe pump in 1956 and is the global leader in highperformance syringe pumps. The PHD ULTRA™ is designed to meet today’s most demanding standards in fluidics applications. trategic Diagnostics Inc., (SDI), a provider of biotechnology-based products and services for a broad range of food safety, life science and industrial applications, has announced it has been awarded US Patent No. 7,521,201 B2 for using bacteriophages in microbiological assay tests and processes. The invention is a rapid bacterial detection method that reduces or eliminates the growth of undesirable bacteria, resulting in improved test performance. The invention addresses the problem of how to detect a harmful pathogen among billions of other bacteria present in a test sample. Reducing the growth of competing bacteria in the sample reduces false negative results, while preventing the growth of cross-reactive bacteria in the sample reduces false positive results. Together, these benefits reduce the time required to obtain test results while improving the accuracy of test methods. In one application, SDI uses this technology in the enrichment media of its RapidChek® SELECT™ Salmonella and E. coli food pathogen assay test kit to inhibit the growth of cross-reactive and competitive bacteria, providing an optimal environment for Salmonella and E. coli to grow and, therefore, be more easily detected. Enrichment media is a significant component of the $1B global food pathogen testing market. Depending on the detection method used, media can represent more than fifty percent of the cost per test. There are more than 138 million tests conducted globally each Be sure to mention, “I read about it in Food Protection Trends”! 814 FOOD PROTECTION TRENDS | NOVEMBER 2009
