Concentrated powders
Concentrated powders are unmixed powders that are
applied with a fingerprint brush. They are more difficult to use than the special
powders.
Cat. No. B-26000/26100
Concentrated Silver, 100/250 ml
Cat. No. B-31000/31100
Bristol Black, 100/250 ml
Soot powder mixtures
The Swedish soot powder mixture is an excellent powder
for use with a brush. It combines a good adhesion to the fingerprint with minimal
adhesion to the background surface.
Cat. No. B-420000/421000
Swedish soot powder mix, 100/250 ml
Special powders
The special powders are mixtures, with better characteristics
than the concentrated powders. Thereby:
- "greasy" features are reduced
- lumps are avoided
- prints show better contrast
- far fewer problems are encountered with excessive use of powder (e.g., smearing
of prints)
Consequently, the development of latent prints can be done much faster, with less
risk and better results.
Silver Special
Very suitable for relatively clean and smooth non-porous surfaces such as glass, painted wood, steel furniture, hard plastic. Excellent contrast against dark surfaces and black gelatin lifters. This powder is suitable for most surfaces found at crime scenes that have to be processed for fingerprints.
Cat. No. B-32000/32100
Silver Special, 100/250 ml
Gold Special
Gold Special provides better contrast against light-colored surfaces than Silver Special. However, it adheres more strongly on surfaces and is therefore less suitable for routine use. Prints powdered with it and then lifted with a gelatin lifter will gradually sink into the gelatin layer.
Cat. No. B-33000/33100
Gold Special, 100/250 ml
Black Special
Like the other special powders, this powder requires
a relatively clean surface. Surfaces well suited to this powder are china, enameled
domestic appliances, and coated papers including cardboard.
Cat. No. B-34000/34100
Black Special, 100/250 ml
