Merck’s Membrane filtration technique complies with international standard such as standard methods for Examination of Water and Waste water, US EPA, and EU testing procedures for drinking water or other filtration testing it’s simple: the test sample is filtered through a microporous membrane, allowing the retention of microbial contamination on top of the membrane. Rinsing removes residues that might inhibit the growth of microorganisms. Once the sample is filtered, nutrient medium is added to promote growth of microorganisms for recovery. For testing non-filterable samples, Merck offers a large selection of culture media of the high quality.

Designed for your lab

Simplify workflow and be confident in your allergen testing process. Neogen™ Allergen Testing Products were designed with your needs in mind by a team of experts who use these tests every day. Based on extensive experience with immunoassay technology and testing thousands of unique food samples, they set out to design tests to detect both processed and unprocessed proteins with a simplified workflow. It took years of careful antibody selection and formulation development to create the simplicity and performance provided by these kits. Supported by Neogen scientists and engineers, these test kits give you the reliability and efficiency you have come to expect from Neogen.

Designed to detect processed and unprocessed proteins

With more variety than ever, today’s food products often require complex processing, which can alter the nature of allergenic proteins in food, making them harder to detect. Neogen™ Allergen Testing Products are designed to overcome this challenge by detecting both processed and unprocessed proteins for more predictable, accurate results in your lab.

Versatility across sample types

Neogen™ Allergen Testing Products can be used on environmental swabs, clean-inplace (CIP) final rinse water, ingredients and food samples.

The Neogen Flip-Top Dilution Bottle is a leak-resistant plastic cylinder with a flip-open lid that seals securely for safe shipping and handling. Neogen Flip-Top Dilution Bottles are ideal diluents for enumeration of microorganisms from food, beverage, and environmental samples. The solution is decontaminated through gamma irradiation for long shelf life. The handy flip-top style provides a fast, easy and reliable bottle for sample processing. The 90 or 99 mL fill volume along with the easy-opening, leak resistant flip-open lid is ideal for collecting, adding, and safely shipping samples. The convenient hinged lid stays open for easy sample addition and the 32 mm bottle opening makes it easy to pipette into and out of the bottle. Each bottle is equipped with an integrity seal that guarantees bottle has not been previously opened. This product is made in the USA and is ISO 9001:2015 certified for quality assurance. It is intended for lab use only.

• Hinged lid stays open for easy sample additions.
• Ready for use with no additional blending required.
• Generous headspace and bottle opening make sample addition easy.
• Leak resistant vial helps prevent leakage during shipping.
• 9 month shelf life from date of manufacture provides long-term readiness.

Results are stored in the Neogen™ Petrifilm™ Plate Manager Software for data analysis.

The Neogen™ Petrifilm™ Plate Reader Advanced enumerates 10 different Neogen™ Petrifilm™ Plates: Rapid Aerobic Count, Rapid Coliform Count, Rapid E. coli/Coliform Count, Rapid Yeast and Mold Count, Aerobic Count, Coliform Count, Enterobacteriaceae Count, E. coli/Coliform Count, Select E. coli Count, Staph Express Count and Staph Express Disk.

• Reads Neogen™ Petrifilm™ Plates in six seconds or less per plate using artificial intelligence to produce accurate results
• Enumerates 11 different Neogen Petrifilm Plates to bring more productivity into your lab
• Includes Neogen™ Petrifilm™ Plate Manager Software to perform insightful analyses that lead to more informed decision-making
• Supports reading of several bar code symbologies for integration into laboratory processes

Following incubation, Neogen Petrifilm Plates can be easily fed into the Neogen Petrifilm Plate Reader Advanced where each plate is imaged and enumerated via onboard fixed artificial intelligence in less than six seconds. Each Neogen Petrifilm Plate artificial intelligence network was trained and validated with a wide assortment of food matrices to ensure accurate plate enumeration.

The Neogen™ Petrifilm™ Plate Manager Software utilizes a simple and streamlined user interface to collect, store, and report Neogen Petrifilm Plate results.
