Sprint Block Stop Bath, Vanilla Scented Indicator Stop Bath for Black & White Films and Papers, 4 Liter

Make your black and white film and paper development process more efficient and user-friendly with the Block Stop Bath, featuring a delightful vanilla scent. This premium quality stop bath solution is specifically designed to halt the development of both films and prints, adjusting the pH levels to ensure optimal results without the harsh side effects commonly associated with conventional stop baths.

The innovative formula of Block Stop Bath includes an indicator dye that visibly changes color to signal when the solution is exhausted, taking the guesswork out of your black & white printing processes. This feature is particularly useful for photographers and darkroom enthusiasts who seek precision and consistency in their work.

Unlike traditional stop baths that contain aggressive acids, which can be hazardous, emit unpleasant odors, and potentially damage your prints, Block Stop Bath is carefully buffered. This buffering action not only minimizes the undesirable side effects but also protects the integrity of your prints. It safeguards the print sizing, which is crucial for preventing fiber damage from fixer thiosulfate contamination - a common culprit behind print deterioration.

Block Stop Bath is an essential component of the SPRINT SYSTEM suite of black & white printing products. When used in conjunction with other SPRINT products, it provides a harmonized signal for the exhaustion of all baths, ensuring a streamlined and efficient workflow. It is also recommended to use Block Stop Bath before fixing with alum hardener to achieve the correct acid value for the fixing stage.

This concentrated solution is economical and space-saving, with one liter of concentrate yielding an impressive 10 liters of working solution. This amount is sufficient for processing approximately 600 8x10 fiber prints, 900 8x10 resin-coated prints, or 600 rolls of film, making it an ideal choice for both amateur and professional photographers.

Please note that due to hazardous material regulations, the Block Stop Bath can only be shipped via UPS GROUND, ensuring safe and compliant transportation of this essential darkroom chemical.

Elevate your black and white photography development with the Block Stop Bath, and enjoy a safer, more pleasant, and more reliable stop bath experience.
