Industry Products region, but not have an adverse effect on the Absorbance of 260/280 ratio. In kinetics mode, the basic plot of absorbance against time may be supplemented with the result for δA/min plus the correlation coefficient is also calculated for the duration of the assay. This slope may be multiplied automatically by a factor to convert it directly to rate of reaction. The Vision Life Science Spectrophotometer has novel Gifford optics for high energy combined with a Xenon source for long life. It includes a unique, integral cuvette tray for storage of expensive cells and sample support. Additionally, an optional integrated printer or wireless Bluetooth connectivity are available. Hoefer, Inc. 800.227.4750 Holliston, MA www.hoeferinc.com performed as well or better than traditional culture methods and with much quicker time to result. “Coupled with the certification, these assays have already received from AFNOR in Europe, this AOACRI validation provides customers with additional assurances of accuracy and reliability,” said Morgan Wallace, senior research microbiologist, DuPont Qualicon. Food processing companies around the world rely on the BAX® System to detect pathogens or other organisms in raw ingredients, finished products and environmental samples. The automated system uses leading-edge technology, 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, 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 www.qualicon.com Hoefer, Inc. New Life Science Spectrophotometers from Hoefer, Inc. oefer, Inc. has announced the introduction of the New Vision Life Science Spectrophotometers. The Vision Spectrophotometers include 16 predefined methodologies for nucleic acid quantification (DNA, RNA and oligonucleotides), protein assays (BCA, Lowry, biuret) kinetics, standard curve, cell density measurements and CY DYE for labeling of PCR Probes. Additionally, the Vision can accommodate up to 90 custom protocols. The combination of the life science methods with rapid scanning, kinetics and concentration capabilities of the Vision Spectrophotometer make it a great addition to any molecular biology or biochemistry laboratory. The visualization of the nucleic acid scan with the full graphic display is particularly useful, especially for RNA samples where impurities might be present in the 230 nm H DuPont Qualicon BAX® System 24E Assays for Listeria Certified by AOAC wo BAX® System assays from DuPont Qualicon have received certification from the AOAC Research Institute as next-day methods for detecting Listeria in food and environmental samples. The BAX® System 24E Assays for detecting Listeria species, an indicator organism, and Listeria monocytogenes, a pathogen, were developed in collaboration with Oxoid, Ltd. Validation studies on hot dogs, spinach, cooked shrimp, queso fresco cheese and stainless steel showed that the BAX® System T Dickson Chart Recorders or on-the-spot written documentation of environmental conditions–temperature, humidity, pressure, or other electronic signal –Dickson chart recorders are your instrument of choice. The larger the chart on the model you select, the easier it is to see data details. Be sure to mention, “I read about it in Food Protection Trends”!
