Basic Yellow 25gm

Chemical Treatment A fluorescing dye stain which can be used for improving superglue CODE
developed fingerprints.
95343
Basic Yellow 40 (Panacryl brilliant flavine) has been found to be one
of the most sensitive stains and fluoresces well between 365nm and
485nm.

Gentian Violet 25gm

Gentian Violet is a dye which stains the fatty constituents of sebaceous sweat CODE
producing an intense purple image. It is very effective for the development of 95341
latent fingerprints on the adhesive surface of adhesive tape and decorative
or protective films.
It will also develop fingerprints on some other surfaces, particularly those contaminated with oils
and grease. Also effective on small non-porous surfaces such as crockery.
Do not use on porous materials i.e. wood, paper, card.
This reagent is easy to use but please note that this product is toxic by swallowing or skin absorptions and
should therefore NOT be used in large quantities.

Ninhydrin Crystals

Ninhydrin is a very effective reagent for paper and some
other porous surfaces. It reacts with amino acids and possibly
some other components in fingerprints. It produces visible
latent fingerprints on surfaces such as cheques, paper
documents, bank notes, wood etc.
Simple to use and cost effective as it does not require any additional
light sources for examination. Reacts with blood and may be used
for developing blood contaminated fingerprints. If used after DFO
additional fingerprints may be developed.
SIZE CODE
Ninhydrin can be used to develop blood contaminated fingerprints on porous and non-porous 25gm 95301
surfaces. Fingerprints developed with ninhydrin can be made fluorescent by application of zinc 100gm 95302
chloride.
