Tetenal Parvofin Developer Tablets For B&W Films (10 Tabs)

Tetenal Parvofin Tabs - 10 tablets Part A and Part B for a maximum of 3 litres black and white negative developer, for 20 films 135-36 maximum. Parvofin is a fine-grain compensation developer in tablet form for all black and white negative films: for classic emulsions as well as for modern T-grain films. Parvofin Tabs go back to a legendary powdered Parvofin formula, which was already launched by Tetenal in the 1950s – the relaunch of the brand is based on the adaptation of the formula to the film emulsions available today, taking into account current legal requirements for the chemical ingredients of photochemicals. Parvofin contains no boron compounds. The mixing of the working solution is carried out by dissolving the tablets Part A and Part B in hot water - after cooling, the developer is ready to use. Two different dilutions, a normal dilution to 150 ml working solution and an economy dilution to 300 ml - or a multiple of each - allow the use of all development cans in all sizes from all manufacturers.
