Nelson-Jameson has the largest collection of reagents assembled exclusively for food and dairy testing laboratories. Reagent chemicals should be handled only by qualified individuals trained in laboratory procedures and familiar with their potential hazards. Right to Know laws make it mandatory that anyone handling a hazardous substance be informed of the health hazards and safety precautions associated with that chemical.
Safety Data Sheets (SDS) are provided by Nelson-Jameson as required by OSHAs Hazard Communication Law for products designed as hazardous. Our automated system assures that you will receive an SDS with your first purchase of that hazardous item. You may also contact us to lookup SDS information on any of the products you are currently using. The absence of a warning, however, must not be interpreted as an indication
Accurate pH analysis is critical in Food Processing areas and Laboratory settings. Small variances may impact food quality, safety, shelf-life, flavor, and consistency. All pH electrodes should be calibrated to pH meters with fresh, unused calibration buffers that bracket the pH value of the product being tested.
For food samples that have a pH range between 4 and 7, electrodes should at a minimum be calibrated using 4.01 and 7.00 pH calibration buffers. Electrodes for samples between 1.68 and 4 should be calibrated with 1.68 and 4.01 pH buffer. For samples between 7 and 10 pH, buffers 7.00 and 10.01 pH are recommended. Also available is 12.46 pH buffer for very high pH products.
Listed above are the most common pH calibration buffers (1.68, 4.01, 7.00, 10.01 and 12.46 pH at 25°C) and many pH meters automatically recognize these values during a calibration procedure. Although not used for calibration, Nelson-Jameson also has 5.00 pH buffer available that is commonly
For everyone in the dairy value chain, the thought of milk contamination is simply unthinkable.
We know that for farmers and their families, competition is tough and professionalization of farming is essential for you to survive and succeed.
Ultimately, healthy products equal healthy profits. This is where the Delvotest can help ensure that any antibiotics given in the herd don't appear in the milk sold.
The Delvotest is a proven, highly respected antibiotic residue testing kit that provides the global dairy value chain (including farmers, dairies, and milk control labs) with peace of mind for a relatively modest investment.
This solution can detect all major antibiotic residues and is suitable for all kinds of milk including cow, sheep, goat, and even buffalo. The kit itself comes in different sizes: So for dairies and milk control labs, we offer larger testing kits, while for farmers we provide a smaller pack with an easy-to-use tray.

Many pH electrodes are shipped with the electrodes moist. Prior to using your electrode for the first time it needs to be conditioned. While it is always best to refer to the manufacturer instructions for proper electrode conditioning, below are three common recommended steps for conditioning your electrode:
- Remove the protective cap or bottle from the bottom of the sensor and rinse the electrode with distilled or deionized water and blot with a Kimwipe®.
- Place the electrode in a beaker containing one of the liquids listed below (in order of ionic ability to condition the electrode.) Soak for 20 minutes.
3.0 M KCI
4.0 pH buffer
7.0 pH buffer
Note: Never condition or store a pH electrode in water long term exposure to purified water will damage the special glass membrane. - After conditioning the sensor for 20 minutes, rinse the electrode with distilled or deionized water and blot with a Kimwipe. The electrode is now ready for calibration
Quite often, customers have questions regarding the subject of hose flexibility. Many different terms are used to describe this attribute of the Saint-Gobain Performance Plastics Sanitary Couplers line. To demystify this complexity, we present a comprehensive Hose Flexibility Glossary. This glossary aims to shed light on key terms utilized in the hose industry, offering formal definitions for concepts such as Bend Radius, Minimum Bend Radius, Dynamic Bend Radius, Static Bend Radius, Force to Bend, and various Pressure Definitions. Whether you're dealing with fluoropolymer hose, all-rubber hose, or metal hose, this glossary serves as a valuable resource to enhance your understanding of hose flexibility parameters.
Discover the world of sanitary gaskets with our comprehensive range of flexible and non-toxic gasket compounds that adhere to stringent FDA specifications. Engineered for direct contact with dairy products and edible oils, these gaskets are also designed to meet the criteria set by 3-A, USDA, and NSF standards. Not only do they exhibit low-swell characteristics, making them well-suited for exposure to oils, steam, and water, but they also won't absorb taste or odors, ensuring the integrity of your products. Our gaskets are available in various materials, including the popular Buna-N, known for its oil resistance, EPDM for steam and hot water service, Viton with exceptional fluid resistance, silicone for outstanding low-temperature flexibility, and Teflon with an impressive temperature range. Each material comes with its unique set of properties, catering to specific application requirements. Shop with confidence, knowing that our gaskets are sold individually, and reach out to our knowledgeable
Prevent premature Washdown hose wear and failure. Washdown hoses are often subjected to physical abuse
while in service. Select a hose that meets or exceeds the application it is intended for.
Consider temperature, pressure, and environmental concerns such as abrasion and chemical resistance.
Every plant should have a maintenance/inspection plan in place to ensure the longest possible life of the hose.
Be sure to consider these steps in your plan:
- Store hose properly when not in use. Hose racks or reels are highly recommended to keep hoses off the floor
and out of harms way. Pay attention to humidity, temperature, ozone and sunlight. Storing out of direct sunlight,
in a room with moderate humidity and a temperature range of 50° to 75°F is recommended. - Always shut off the water supply to the hose when not in use and open the nozzle to relieve the pressure before storing. Leaving water in the hose subjects it to constant pressure
Flagged vs. Unflagged Broom Bristles
There are many options when looking at the bristles in your broom's material including stiffness, color, and flagged or unflagged bristles.
Both flagged and unflagged brooms have applications within facilities. Choosing the correct one can make your clean-up job easier.
Flagged—Bristle ends look like split hairs. These bristles are ideal for sweeping up fine powders or debris in dry areas. When used in wet applications it is common for these bristles to become matted-up and dirty.
Unflagged—Bristles are commonly used in wet applications and are ideal for larger debris. They will not, however, sweep up the fine debris as effectively as a flagged bristle will.
Dive into a world of versatility with our extensive gasket line tailored for the unique demands of the food and beverage industries. At your fingertips, you'll find a diverse array of sizes, colors, and materials, meticulously chosen to meet the stringent requirements of these industries.

Both consumers and food industry interests benefit from being fully informed about the true nature of foodborne illnesses. The complex realities of foodborne illnesses demand that formal medical insight and study is needed to determine the type of outbreak being dealt with at any given time and place. Still, it can be of benefit for any stakeholder in the food industry to learn more about these differing illnesses and their effects on consumers.
For example, just within the realm of bacterial outbreaks, incubation times can range from a few hours to a few months and symptoms can range from fevers and headaches to severe abdominal pain and paralysis, depending on the type of bacteria. The following graph from the CDC* describes incubation periods, symptoms, and other information about foodborne illnesses for a general audience.
