Each capsule is a single-use testing pod containing NIMA’s proprietary reagents. When you close and twist the lid, the capsule automatically mixes your food sample with these reagents. The NIMA Sensor analyzes the chemical reaction inside the capsule and displays whether gluten is detected in the portion you tested.

NIMA is designed to test solid or semi-solid foods that can fit easily into the capsule and mix evenly with the testing liquid. You can test a wide range of foods, such as:

• Cooked or baked foods like bread, pasta, or pizza toppings
• Grains and cereals
• Sauces, dressings, and spreads with thicker textures
• Meats, vegetables, or mixed dishes when you can take a small, uniform sample

Your NIMA Sensor detects gluten from wheat, barley, and rye at 10 parts per million (ppm) or higher in the portion you test. For the most reliable results, take a pea-sized sample that represents what you plan to eat and follow the sampling tips in the User Manual.

Some foods and ingredients cannot be tested accurately because of their texture, composition, or how gluten proteins behave during processing. These include:

• Fermented or hydrolyzed foods and alcoholic beverages, such as soy sauce, beer, or vinegar
• Pure liquids, such as soups, beverages, or thin sauces
• Oily or high-fat foods, such as nut butters, oils, or melted cheese
• Very dry, powdery, or crumbly foods that don’t mix evenly in the capsule
• Non-food items, including gums, supplements, or vitamins
• Acidic foods CAN be tested, but be sure to put no more than a pea-sized amount and it is a good practice to dilute the sample with an equal portion of 2 - 3 droplets of water.

Your NIMA result reflects only the sample you test, not the entire meal. Gluten may be unevenly distributed in mixed dishes, so testing small samples from different parts of a meal can help identify hidden gluten.

No. Capsules are one-time use only and should be used immediately after opening. Reusing or saving a capsule can lead to inaccurate results and may damage your Sensor. Store unopened capsules in a cool, dry place away from heat, humidity, and direct sunlight to maintain accuracy (recommended storage temperature 32°F (0°C) and 90°F (32°C).

Each box is printed with an expiration date on the packaging. Capsules remain stable for about 12 months from manufacture when stored properly. Always check the expiration date before testing — using expired capsules may reduce result reliability.

If you see liquid leakage, if the lid won’t twist fully closed, or if you feel unusual resistance when sealing, do not run the test. Please contact customerservice@nimanow.com with your order number and photos of the capsule. Our team will help you identify the issue and, if needed, send a replacement.
