The product information we have put on the website so far can be found in the navigation menu on the left side. Over time a number of things should be added, such as information on the fingerprint powders (what powder to use on what surface), Silmark, ninhydrin solutions, cyanoacrylate and cyanoacrylate staining solutions, DFO, and more information on staining solutions for blood.

A number of things allready added to the Dutch product information section are not here yet. But that can also be said of the Dutch section (there is no manual of use for the gelatin lifters in the Dutch section for example).

When you are looking for something and you can't find it, we warmly recommend the search engine on the site.
