Processing power

Chemical set enables one to process 1 square meter of the photomaterials or ~100 sheets (102x127mm) of PFG-01 or VRP-M film.



The developer’s solution remains developing properties while stored in dark room conditions for three days. Bleaching solution can be stored in dark room conditions for about one month. Processing even one film in the developing and bleaching solutions noticeably reduce their lifetime. All solutions should be stored in the closed glass or non-active plastic bottles in a room temperature and darkness.


Work with chemicals

It is important to follow good laboratory practice while processing the photomaterials. The chemicals included in Geola’s set are not poisonous, however, please wipe up any spillage as soon as it occurs and use the polythene gloves.
