Ammonium Thiosulfate 60% Solution Photography Grade

Premium Ammonium Thiosulfate 60% Solution – The Rapid-Fixing Powerhouse for Advanced Pyrotechnic & Photographic Applications

Bring unmatched speed and reliability to your specialized pyro or wet-plate collodion workflows with Ammonium Thiosulfate 60% Solution – the professional-grade rapid fixer that's a staple in photography and finds niche use in certain pyrotechnic processes requiring fast, clean silver halide removal or sulfur-related chemistry!

This clear to pale yellowish liquid (typically 58–60% active ammonium thiosulfate, (NH₄)₂S₂O₃) delivers superior performance as a rapid fixer and chemical reagent:

• Lightning-fast fixing action — Clears silver halides far quicker than traditional sodium thiosulfate fixers, making it ideal for high-volume processing, wet-plate collodion negatives/positives, archival prints, or any silver-based photographic work where time is critical
• Neutral to mildly alkaline pH — Gentle on emulsions and pyro-stained negatives; reduces risk of bleaching or staining compared to acidic alternatives, perfect for delicate or historical processes
• High solubility & stability — Fully water-miscible, low odor (mild ammonia note), and stable in solution for extended shelf life when stored properly; easy to dilute or mix with sulfite hardeners for enhanced performance
• Versatile chemical utility — In pyrotechnics, serves as a source of thiosulfate ion for specialized reactions, sulfur donation, or as an additive in experimental comps involving silver compounds, smoke effects, or desensitizing agents (consult advanced formulas – not a primary fuel/oxidizer/binder)
• Clean & efficient — Leaves minimal residue, washes out readily, and supports eco-friendlier workflows compared to older fixer chemistries

Whether you're mastering wet-plate collodion for stunning ambrotypes/tintypes, processing large-format negatives, or exploring niche pyro applications where rapid silver complexing or sulfur chemistry matters, this 60% solution gives you the edge in speed, clarity, and consistency that pros demand.

Key Advantages at a Glance:

• Clear liquid, 58–60% concentration – ready-to-use or easily diluted
• Rapid-acting ammonium thiosulfate fixer (faster than hypo/sodium thiosulfate)
• Neutral pH profile – safe for pyro-stained or delicate emulsions
• Excellent for wet-plate, film, paper, and archival fixing
• High purity, photography-grade – minimal impurities for clean results
• Multi-use potential in advanced chemical/pyro experiments
• Safe handling (store cool, away from strong acids/oxidizers; ventilate ammonia fumes)
