For successful pH analysis, proper handling and maintenance of pH electrodes are crucial. Upon receipt, carefully inspect for damage, and initiate the first-use procedure as per the manufacturer's instructions. Regular calibration with fresh pH buffers is essential, along with checking electrode slope if required. Proper storage is crucial, especially for backup electrodes, following the manufacturer's recommendations. Hydrate electrode sensing ends between samples and during storage in the recommended solution. During usage, rinse with water and use soft tissue for blotting, avoiding wiping the sensing end. For hot or cold product analysis, employ an automatic temperature compensator (ATC), ensuring temperature consistency for accurate results. Cleaning electrodes at least once daily is vital, involving soaking in a fat solvent or diluted detergent, followed by rinsing, blotting, and storage in a solution. Understanding these tips ensures optimal electrode performance and accurate pH analysis.

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

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
- Store hose properly when not in use. Hose racks or reels are highly recommended to keep hoses off the floor
