Stainless Steel Grade Test Liquid 12/15ml – 201 304 Detection

Stainless Steel Grade Detection Liquid – Instant Material Identification

Know exactly what you're working with. This professional-grade Stainless Steel Test Liquid is a compact, easy-to-use reagent that instantly identifies and distinguishes common stainless steel grades — including 201, 202, 301, and 304 — through a fast, visible color reaction. Whether you're verifying tableware, sanitaryware, building materials, or industrial fittings, this detection agent delivers clear, on-the-spot results without the need for a laboratory.

Key Features

• Rapid Color Reaction: Triggers a visible color change in as little as 10 seconds via a fast manganese reaction, giving you clear contrast for instant interpretation.
• High Detection Accuracy: The advanced reagent formula interacts directly with the internal metal composition, delivering swift and dependable alloy grade identification.
• Portable & Convenient: Available in 12ml or 15ml single-use vials with precisely measured quantities — ready for on-site, field, or home use without any extra equipment.
• Wide Range of Applications: Suitable for stainless steel tableware, kitchen tools, sanitaryware, construction and building materials, industrial equipment, and metal recycling verification.
• 3-Year Shelf Life: Long-lasting formula retains potency for up to 3 years when stored properly.
• No-Clutter Design: Compact, portable vials keep testing simple, clean, and efficient — at home or on the job.

How to Use

1. Prepare the surface: Clean the area to be tested thoroughly, ensuring it is free from oil, grease, or residue before applying the liquid.
2. Apply the reagent: Place a small drop of the detection liquid directly onto the stainless steel surface.
3. Observe the reaction: Watch for the color change within 10 seconds — the resulting color indicates the steel grade.
4. Clean after testing: Wash the tested area with household detergent and warm water after use. For tableware, test only in areas away from mouth contact.

Usage Tips

• This reagent may leave a faint mark on the surface. Always test in an inconspicuous area first.
• Keep away from children and store in a cool, dry place away from direct sunlight.
• For best results on tableware, test the underside or base of the item.
