Know Your Stainless Steel in Minutes – No Power Needed Uncertain about the stainless steel used in your cookware, tools, or materials? This professional-grade testing reagent offers a simple, rapid, and battery-free solution for anyone who needs to verify stainless steel composition on the spot. How It Works The reagent reacts chemically with certain metal elements (such as manganese) commonly found in lower-grade stainless steel. When applied to a clean, room-temperature surface, it produces a visible color change within about 2 minutes. By comparing the resulting color to the reference chart provided in the instruction manual, you can quickly assess whether the material meets expected quality standards. Why Choose This Reagent? No electricity, no meters – Pure chemical detection. Use it anywhere – at home, in a warehouse, at a scrapyard, or on a construction site. Over 200 tests per 15mL bottle – Each tiny drop counts. Ideal for frequent testing or batch verification. Non-destructive – Leaves minimal residue and does not damage the tested surface, allowing you to inspect finished products or raw materials without harm. User-friendly instructions – Every package includes a clear instruction sheet. No laboratory training required. Typical Applications Kitchenware & Tableware – Pots, pans, thermoses, spoons, forks, knives, cups, and food containers. Sanitaryware – Sinks, faucets, showerheads, bathroom accessories. Construction Materials – Handrails, cladding, structural supports, pipes. Industrial Machinery – Equipment parts, storage tanks, conveyor components. Metal Recycling – Quick sorting and verification of stainless steel grades during scrap processing. Instructions for Use Ensure the test surface is clean, dry, and at room temperature (approx. 20–30°C / 68–86°F). Apply one drop of the reagent onto the surface. Wait about 2 minutes. Compare the resulting color with the instruction chart to interpret the result. Important Notes Store the bottle tightly closed in a cool, dry place away from direct sunlight. Keep out of reach of children. Avoid contact with eyes and skin – use gloves if needed. Do not use on painted, coated, or heavily oxidized surfaces without cleaning first. For best accuracy, test on a representative area of the base material. A Smart, Cost-Effective Choice Lab testing can be expensive and time-consuming. This reagent provides a practical alternative for routine verification, on-site checks, and preliminary screening – all at a fraction of the cost and without waiting days for results.
