Product Description
Nickel Test Kit is a two-reagent set containing ammonia solution and dimethylglyoxime, commonly abbreviated as DMG. It is used for rapid qualitative screening of nickel released from metal objects and metal components used in garments, textiles and accessories.
Dimethylglyoxime reacts with nickel ions in an alkaline ammonia medium to form a pink or red-coloured complex. When the test swab develops this characteristic colour after rubbing the prepared metal surface, the result indicates detectable nickel release under the screening conditions.
This locally supplied set contains one 20ml bottle of ammonia solution and one 20ml bottle of dimethylglyoxime solution. It is intended for routine inspection and screening, not for measuring the exact nickel-release rate or total nickel percentage.

Product Overview
Nickel is commonly used in metal alloys, plating and accessory components. A dimethylglyoxime screening test helps identify whether nickel ions are released from a tested metal surface under the chosen procedure.
The method is especially relevant to garment and textile accessories that may touch the skin, including buttons, rivets, zippers, snaps, buckles, hooks and decorative metal components. It can also be used as a preliminary check for jewellery, watch parts, spectacle components and other metal articles.

Key Benefits
Fast Visual Screening
The result is judged by a visible colour change rather than an electronic reading. A pink or red response provides an immediate indication that detectable nickel has been released during the test.
Suitable for Garment Accessories
The reagents can be used on commonly tested metal parts such as buttons, snaps, zippers, buckles and decorative trims.
Simple Two-Reagent Format
The set supplies the ammonia and dimethylglyoxime solutions needed for the basic qualitative reaction.
Portable and Practical
The compact bottles are convenient for quality-control laboratories, sample rooms and on-site inspection work.
Supports Preliminary Compliance Screening
The kit can help identify samples that may need formal confirmation by an accredited nickel-release test method.
Who Should Buy This Product?
- Garment manufacturers and exporters
- Textile and apparel testing laboratories
- Buying houses and third-party inspection teams
- Metal accessory suppliers
- Quality-control and compliance departments
- Jewellery and fashion-accessory businesses
- Universities and technical training laboratories
- Institutional buyers requiring routine nickel screening reagents
Usage and Handling Summary
Follow the instructions supplied with the current product batch. A general screening procedure is summarised below:
- Clean the metal test area so that oil, dirt, polish or surface residue does not affect the swab.
- Wear suitable gloves and eye protection, and work in a well-ventilated area.
- Apply approximately two drops of ammonia solution and two drops of dimethylglyoxime solution to a clean cotton swab, unless the supplied instructions state otherwise.
- Rub the moistened swab firmly over the selected metal area for approximately 30 seconds.
- Observe the swab and contact area under clear lighting.
- A pink or red colour indicates a positive nickel-screening response.
- No pink or red colour means nickel was not detected under that screening procedure; it does not prove that the item is completely nickel-free.
- Test separate components individually because different parts of one article may have different metal composition or plating.
- Use a fresh swab for every test to prevent cross-contamination.
- Close both bottles tightly after use and record the sample identification and result.
Limitations and Important Considerations
- This is a qualitative screening test. It does not measure the exact amount or release rate of nickel.
- A positive result should be confirmed using an appropriate reference method when regulatory or contractual compliance is required.
- CEN/TR 12471 describes dimethylglyoxime screening for nickel, while EN 1811 is used as a reference method for formal nickel-release measurement on relevant articles.
- A negative screening result does not guarantee that an item contains no nickel or will never release nickel under other conditions.
- Protective coatings, plating, dirt, oil or varnish can affect contact between the reagent and the metal surface.
- Some surface finishes may discolour or become dull during testing. Test an inconspicuous area first when appearance is important.
- Alternative colours can occur from other metals or surface contamination, so interpretation should focus on the characteristic pink-to-red nickel reaction.
- Ammonia vapour can irritate the eyes and respiratory system. Avoid inhalation and use adequate ventilation.
- Avoid skin and eye contact with both reagents. Rinse immediately with plenty of water following accidental exposure and obtain medical assistance when required.
- Exact reagent concentration, solvent, shelf life and SDS details were not confirmed from the product label. Contact Inaya Scientific for confirmation.

Frequently Asked Questions
What is the Ammonia and Dimethylglyoxime Nickel Test Kit used for?
It is used for qualitative screening of nickel released from metal surfaces. The kit is commonly applied to garment and textile accessories such as buttons, zippers, snaps, buckles and decorative metal trims.
What is included in one Nickel Test Kit set?
One set contains a 20ml bottle of ammonia solution and a 20ml bottle of dimethylglyoxime solution. Cotton swabs or other accessories have not been confirmed, so contact Inaya Scientific for the exact current package contents.
How does dimethylglyoxime detect nickel?
Dimethylglyoxime reacts with nickel ions in the presence of ammonia and forms a pink or red-coloured complex. The characteristic colour provides a visual positive screening indication.
How do I use this nickel test reagent set?
Apply the reagents to a clean cotton swab and rub the selected metal surface firmly according to the supplied instructions. A common local procedure uses approximately two drops of each solution and about 30 seconds of rubbing, but the current product instruction should take priority.
What does a pink or red test result mean?
A pink or red colour means the screening test detected nickel released under the test conditions. It is an indicative result and should be confirmed by a formal laboratory method when compliance decisions are required.
Does a negative result mean the product is completely nickel-free?
No, a negative result only means nickel was not detected by that screening procedure. Coatings, low release levels, surface condition and test technique can affect the outcome.
Can the kit be used for garments and textile accessories?
Yes, garment and textile metal accessories are the main stated application. Buttons, snaps, rivets, zippers, buckles, hooks and decorative metal parts can be screened individually.
Is this kit suitable for official nickel-release compliance testing?
No, the kit is intended as a qualitative screening tool rather than a quantitative compliance test. Formal decisions may require an accredited method such as EN 1811 for relevant skin-contact articles.
How should the ammonia and DMG reagents be stored?
Keep the bottles tightly closed in a cool, dry and well-ventilated place away from heat, direct sunlight and children. The exact storage temperature and shelf life for this supplied formulation were not verified, so contact Inaya Scientific for confirmation.
Where can I buy this Nickel Test Kit in Bangladesh?
You can order it from Inaya Scientific, subject to stock availability. Nationwide delivery and quotations for bulk, factory and institutional requirements are available on request.
Closing Recommendation
The Ammonia and Dimethylglyoxime Nickel Test Kit is a practical option for rapid preliminary screening of garment, textile and accessory metal components. Its two-reagent colour method helps quality-control teams identify samples that may require further laboratory confirmation.
For trustworthy results, clean the test surface, use fresh swabs, follow the supplied reagent instructions, work under good lighting and treat every positive response as a screening indication rather than a final quantitative result.
