Durston 1976 Ultra-Pure White 1 Gram Rhodium Bath Concentrate - 145.619

Durston 1976 Ultra-Pure White 1 Gram Rhodium Bath Concentrate - 145.619

Durston 1976 Ultra-Pure White Rhodium Bath Concentrate delivers 1 gram of rhodium in a professional-grade 50ml (1.69 oz) concentrate formulated for clean, bright electroplating with excellent coverage and reflectivity. Designed for jewelers who perform bath rhodium plating, this concentrate dilutes with deionized water at 1g per 500ml to yield exactly 500ml (16.9 oz) of working solution — just over one pint — making it efficient and straightforward to prepare.

The formula is engineered for consistent white finish results across a variety of metals. It performs particularly well on gold and silver. When plating copper or brass, a suitable undercoat — such as silver, nickel, palladium, or platinum — is recommended prior to rhodium plating. Excellent throwing power helps achieve full, even coverage on intricate and detailed pieces, making this concentrate a trusted choice for precision electroplating in professional bench environments.

Q&A

Maintenance Tips

• Handle as hazardous chemical first – Store in a sealed, labeled container in a cool, dry, ventilated area away from acids, bases, and reducing agents. (Rhodium salts are corrosive and regulated.)
• Use clean DI water only – Always dilute with deionized/distilled water to prevent contamination and unstable plating results; impurities directly reduce brightness and adhesion.
• Prevent metal contamination – Never return used solution to stock. Even trace copper, nickel, or steel contamination will permanently degrade bath performance.
• Keep bath covered when not in use – Limits evaporation, dust contamination, and oxidation drift that affects plating consistency and throw power.
• Maintain correct undercoat system – For copper/brass, ensure proper nickel/silver/palladium underplating before rhodium to prevent peeling or dullness.
• Control temperature strictly (if bath is prepared) – Avoid overheating; excessive heat can destabilize whitening agents and reduce deposit quality.
• Use dedicated equipment only – Beakers, leads, anodes, and agitation tools should never be mixed with other plating chemistries to avoid cross-contamination.
• Filter solution if reused in system – Fine particulate contamination should be removed with plating-grade filtration to maintain mirror finish quality.
• Store unused concentrate tightly sealed – Prevent moisture absorption and evaporation loss of active rhodium content.
• Dispose responsibly – Spent solution must be handled as hazardous precious-metal waste and recycled through approved refiners.
