Listeria PatternAlert assay rapidly identifies molecular patterns from Listeria strains to assist food producers in identifying harborage sites for persistent Listeria and in tracing back sources of contamination. The assay, which is performed using the fully automated Encompass Optimum workstation, enables users to detect molecular patterns in just six hours directly from a positive enriched sample, without the need for an isolate. Each result can be matched against a user’s specific PatternAlert database to identify their pattern matches across locations and time. Each pattern generated by the assay encompasses a group of strains and may include multiple species of Listeria. Rheonix, 607-257-1242, www.rheonix.com.

NGS-Based Platform for Pathogen Testing
Clear Safety is an end-to-end NGS-based food safety platform for high-volume routine pathogen testing. According to the company, by combining NGS sequencing, advanced microbiology, robotic automation, data science, and software analytics, a 99.9% accuracy can be achieved while lowering costs. The platform collects hundreds of millions of data points per analysis to learn everything about a pathogen in a single test. The first release of the platform supports high-volume Salmonella testing. Listeria and E. coli testing will be rolled out in 2019. All tests go from sample to answer in under 24 hours.

With print speed up to 4.5 in. per second, the LX910 can handle labels as wide as 8 in. and as small as 0.75 in. According to the company, banding is virtually eliminated—even on the faster print speeds. Both dye-based ink and pigment ink work interchangeably on the same printer, while a new print head is provided each time the cartridge is changed. Typical applications include product labels for coffee, wine, water, bakery, confectionary, meat, cheese, and other specialty and gourmet foods. The printer is also ideal for manufacturing, laboratory, government, retail, and a wide variety of other markets. Primera Technology, Inc., 800-797-2772, www.primera.com.
The GO Real-Time Reusable Tracker, a new version of the GO Real-Time Tracker, allows users to recharge and reuse the device. It provides visibility of location and temperature of perishable shipments in real time, via a cellular connection. It’s suitable for use in scenarios where customers own their own trucks and/or control both the start and end point of a shipment. Emerson, 314-553-2000, www.emerson.com.
Wine pH Tester
The Wine pH tester (HI981033) is engineered to solve the challenge of measuring samples with a higher solids content. The ideal pH tester for wine making, this tester is crafted to measure the pH in juice, must, and wine. The company says the probe features Clogging Prevention System sleeve junction technology that resists clogging up to 20x longer than a standard ceramic frit. A spherical glass tip design allows the probe to come in direct contact with a wider area of the wine sample for a faster pH measurement. Equipped with a glass body, the electrode is easy to clean and chemically resistant. The glass body is also able to quickly reach a thermal equilibrium.

The DART QDa System with LiveID is a direct-from-sample analytical system that allows laboratories to answer questions such as: Is the sample authentic? Has the composition of the sample changed? Is the sample quality good or bad? Direct Analysis in Real Time (DART) is a direct and rapid analysis technique for various sample types with minimal sample preparation and no requirement for a chromatographic separation. The source directs heated, ionized gas at the surface of the sample between the DART interface and the QDa detector where the ionized molecules are detected. The LiveID software provides the user with the capability to train and validate multivariate statistical models using the chemical profile obtained from the DART QDa analysis. The LiveID models can be used to classify the identity of unknown samples, generating results in near real time and a simple yes/no answer in seconds. Waters Corp., 800-252-4752, www.waters.com.
The XRBHR series of monoblock X-ray sources are designed for OEM applications powering their internal bipolar X-ray tube to 80kV and 100kV at power levels of 100W, 210W, 350W, and 500W. Features such as universal input, compact package size, and standard RS-232 or Ethernet digital interface simplify integration of any XRBHR model into a user’s X-ray system. These intelligent power supplies monitor and log over two dozen operations, using a real-time clock to record total X-ray ON time. Each XRBHR model is available with fan (standard) or cone (optional) beam geometries. Spellman High Voltage Electronics Corp., 631-630-3000, www.spellmanhv.com.
Detectable Rubber Gloves
Powder-free metal detectable gloves are made from natural rubber and the anti-slip patterned finish provides a good grip in wet and dry conditions. Designed for safe use in food processing, the gloves comply with FDA and EU regulations for contact with food. The metal detectability reduces the risk of contaminated products and the bright blue color makes them highly visible if lost in the process area. Gloves have a higher resistance to tearing with a specification for an 0.018-in. thickness. Extra benefits are derived from the bacteriostatic and fungistatic additives that prevent the growth of microbial contaminants. In addition, the low level of soluble proteins reduces the risk of negative skin response. Detectamet, 844-820-7244, www.detectamet.com.
The newly designed pull test kit includes an improved polarity indicator to allow users to verify the pole configuration of the separation equipment. Another useful feature of the indicator shows the user how far the magnetic field actually extends beyond the surface of the magnet, which helps determine spacing between cartridges for a given application. The optional version has a digital scale that comes with NIST calibration check certificate. While all industries should utilize a pull test on their magnetic separators, the company emphasizes that with the attention on food safety being so high, it’s required in every facility that transports, processes, or packages food.

Mix Proof Valves
Offering minimized CIP fluid losses, the D4 Series of mix proof hygienic valves is used for the separation of dissimilar products across the food and beverage, dairy, and brewing process industries. All D4 valves are fully balanced for dependable operation against pressure spikes and flow in any direction. Automated processing is enhanced with the option of a unique control unit with integrated seat lift detection and no external sensors. Compressed air or lifting tools are not required for removal and service. The D4 range includes the primary D4 model, which meets the basic needs for reliable product separation and seat lift or non-seat lift cleanability, and the DA4 ultra-hygienic model for critical applications requiring enhanced cleanability of all product contact surfaces. For applications where the current generation DA3+ housing is reliably in place, the DA4 can be inserted to provide an efficient upgrade, future-proofing existing installations with minimal disruption and risk.
