- Used For: Black and White Film/Paper
Photographers' Formulary 03-0165 Overview

The Photographer's Formulary Hypo Clear Agent aids in the archival process It removes the residual fixer in film and paper.

It works based upon ion exchange: ions adsorbed onto a solid film or paper can be replaced by ions of a solution such as those found in the Hypo Clear solution.

The net effect is that the adsorbed thiosulfate ions of the hypo (difficult to remove by a water wash) are replaced by sulfite ions (readily removed by a water wash).

Hypo Clear does not decrease the total number of ions absorbed on the paper, it merely exchanges those ions originally on the film or paper with those of Hypo Clear.

Note:> Washing after the use of Hypo Clear is imperitive.

The chemicals in this kit are used to make the stock solution which is diluted 1:9 to make the working solution.
