3 S-Biokit

Skin Surface Stripping in Dermatology

Biokit neu Quadrat

The 3 S-Biokit set is a quick, easy and economical method for a multitude of diagnostic possibilities in a least invasive way for dermatology, veterinary medicine and many others.


The stratum corneum holds a variety of information, not only on the skin itself but also on the metabolism state of the complete body. Therefore biopsies of the skin surface play an indispensable role in dermatology.

The 3 S-Biokit works with a fast hardening cyanoacrylate glue to remove a superficial layer of the stratum corneum (of a thickness of 2-3 cells). The glue polymerizes under slight pressure and generates a compound with the same optical properties as glass. This biopsy gives information on the in vivo state of the stratum corneum. It can be dyed and examined under a microscope.

Alternatively it may be used as a very quick, safe and time saving method for induced irritation by skin surface strippings. For the widely used tape stripping you need to perform 10-15 strippings leading to a result, which cannot be safely reproduced. According to our experience, with only two strippings with the 3S-Biokit very good results are achieved.
