In developing latent prints with iodine, a long-used method, iodine crystals give off vapors (sublimation) that adsorb physically to the oily substances of a fingerprint.

The brown-colored prints that are developed with iodine are not permanent unless fixed. Benzoflavone fixes and also darkens the print.

The iodine fuming technique can be used on both porous and non-porous surfaces. It works best on fresh prints (usually no more than a few days old).

Iodine fumes are toxic and also strongly corrosive.

Since the iodine fuming technique is in principle non-destructive, other techniques can be used afterwards (e.g., the ninhydrin treatment of paper).

Contents of iodine fuming kit B-5000

Iodine fumerFingerprint developed with iodine, the right part fixed with benzoflavone

Cat. No. B-71000
Complete set of chemicals for iodine fumer, which consists of: B-71300, calcium chloride, 100 ml bottle; B-76000, iodine crystals (50 g in a glass bottle); and B-71500, 100 ml bottle filled with glass wool.

The function of the calcium chloride is to dry the air stream carrying the iodine (wet iodine vapor is more corrosive than dry vapor). The glass wool is meant to keep everything in place in the iodine fumer.

Cat. No. B-72000
Iodine fumer with rubber balloon

Cat. No. B-76000
Iodine crystals, 50 g in brown glass bottle

Cat. No. B-73000
Silver plate (for the lifting of prints developed with iodine, 5 x 5 cm)

Cat. No. B-73100
Cleaner for polishing the silver plate

Cat. No. B-74500
Iodine fixing solution, benzoflavone-based (in a mixture of cyclohexane and dichloromethane). With this fixative, light-brown iodine developed, non-permanent prints will be fixed with a dark blue color (see photograph left).
