Kentmere Black and White Rapid Fixer (Liquid Concentrate, 500mL, Makes up to 5L)
Non-Hardening Archival Rapid Fixer – Universal Formulation for Black and White Films and Darkroom Prints, Precision Chemical Clearing Action, Dual Substrate Compatibility (RC Papers, FB Papers, and Monochrome Negative Films), Concentrated Liquid Chemistry with 1:9 Dilution Ratio, 500mL Bottle Yields Up to 5 Liters of Working Strength Solution (Fresh Stock / Mint Condition)
Kentmere Black and White Fixer is a professional-grade liquid concentrate engineered to provide rapid, thorough, and reliable chemical clearing of unexposed silver halides in traditional photographic darkrooms. Designed for darkroom printers, lab technicians, and analog photographers, this precision-formulated fixer halts light sensitivity, rendering negatives and photographic prints completely stable for long-term archival permanence and daylight handling.
Formulated for maximum versatility across analog workflows, Kentmere Fixer delivers dependable clearing times whether processing in manual daylight inversion tanks, open processing dishes, or manual darkroom trays. The concentrated liquid formulation eliminates the inconvenience of dissolving dry powders, ensuring rapid, dust-free preparation. Mixed at the recommended standard 1:9 dilution ratio (1 part concentrate to 9 parts water), this 500mL bottle produces up to 5 liters of active working strength fixer. It works cleanly across all black-and-white materials, including fast-clearing resin-coated (RC) papers, traditional fiber-based (FB) exhibition papers, and standard 35mm, 120, and sheet films.
