White rectangular 20-litre jug of black-and-white film developer concentrate

Sprint/Nextel

Sprint/Nextel Standard B&W Film Developer 20 L

SKU CH-HN10-ZCY5T

Liquid concentrate makes 10 litres of working solution per litre to develop 50 rolls, or 110 rolls with replenishment

  • Makes 10 litres of working solution per litre of concentrate
  • Develops at least 50 rolls per 10-litre batch
  • Replenished solution extends capacity to 110 rolls
  • Inhibits agitation streaks and protects highlights from over-development
  • Formulated without Metol to reduce risk of skin irritation

Product purpose

Sprint Standard Black & White Film Developer is a liquid concentrate for processing black-and-white negative film. It is intended for photographers and labs that mix their own working solutions and want a developer free from Metol.

Key yield figure

One litre of concentrate makes ten litres of working solution, enough for at least fifty rolls of film or one hundred and ten rolls when replenished. This dilution ratio is the single specification that determines whether the volume suits your throughput.

Installation and pitfalls

Mix the concentrate with water at the stated dilution before use and follow the standard developing sequence with stop bath, fixer, hardening converter, fixer remover and wetting agent. The most common error is skipping the replenishment calculation, which reduces the total roll count well below the rated one hundred and ten.
