pHoton High Purity Photographic Storage

High purity photographic storage products for delicate photographic glass plates, negatives and prints.

The pHoton™ system includes a specially developed range of papers, folders, envelopes and pockets created from 100% cotton, un-buffered, high purity silver image safe paper.

About pHoton™

Conservation by Design classify pHoton™ as ‘high purity’ to distinguish between it and ordinary acid free paper. pHoton™ is produced to a fixed quality standard for CXD by the Munktell Mill, founded in 1740 and the world’s first maker of chromatography and filter paper.

pHoton™ is made on a machine that is one metre wide which only produces white paper in qualities designed for specialist filtration, medical, conservation and scientific uses.

Converted products include:

  • pHoton™ folder for prints and document storage.
  • pHoton™ Four Flap Enclosure for glass plates.
  • pHoton™ Sleeves and Pockets ‘Stitch in Timecare’ for the storage of negative film. Tailored to meet most common sizes: 35mm, 60mm and 70mm film. Sleeves are sewn with cotton thread to guarantee that nothing can accelerate the ageing of the film.

The porous nature of the paper prevents the build up of harmful gases within the enclosures which can happen with less porous storage papers and plastic enclosures.

pHoton™ High Purity Papers

These 100% cotton, high purity, silver image safe papers and photographic storage products are produced for CXD at the Munktell paper mill which is famous for the production of the world’s first filter paper. They have been developed in collaboration with leading photographic conservators and institutes of conservation.

The pHoton™ range consists of papers made from un-sized pure cotton fibres which are virtually 100% pure alpha cellulose containing no chemicals whatsoever and because of this they are probably the purest of all photographic storage papers. They are un-calendered to allow maximum airflow and prevent any potentially harmful build up of gases that may be emitted by the photographic material stored within the enclosure. Due to their purity and porosity, these papers can be used safely for long term storage of all kinds of photographic materials be they negatives or prints and irrespective of the photographic technique used to create them. They can, of course, be used for storing any object requiring a non alkaline paper.
