Technical Information: Jar Testing for Compatibility

Jar testing is the most practical way to determine the compatibility of a proposed product mix. A jar test should be done before mixing Floratine products with other, non-Floratine products.

Materials Needed:

• A glass or plastic jar, approximately one quart or one liter
• A graduated cylinder for measuring small quantities of product
• A stir rod or spoon

Calculations:

A jar test tests a small amount of what will be mixed on a larger scale. It will be necessary to do some basic calculation before measuring out water and product, and it is usually the most practical to convert all units from gallons and ounces to milliliters. The following conversions will help:

• 1 gallon = 128 ounces
• 1 gallon = 3.785 liters (3,785 milliliters)
• 1 ounce = 29.6 milliliters

Divide the total spray volume of the tank by 1 quart or 1 liter to figure out the scale of the experiment. For example, a total spray of 100 gallons will divide into 1 liter by the following equation:

All other numbers will be divided by 378.5.

Doing the Test:

• Add one quart of water to the container (make sure to use the same water that will be used in the rig)
• Add the proper amount of product in the order it would be added in the rig
• Stir vigorously for one minute
• Allow mix to sit undisturbed
• Watch for abnormalities

What to Watch For:

The following signs indicate an undesirable reaction, and that the mixture is incompatible:

• Gelling or thickening
• Flake or crystal formation
• Violent bubbling or heating
• Extreme color changes
