The new Forensic Swabs from SARSTEDT are suited for the collection of both reference samples and evidence of DNA traces at crime scenes. The ventilation membrane in the tube base enables self-drying of the swab within the tube. A dry swab prevents bacteria and mildew growth, which make analysis impossible and destroy the sample. Drying of the swab in the open, i.e. outside the tube, as in standard systems is unnecessary, thereby excluding the risk of mix-up and contamination.
The Forensic Swab is produced under the most stringent hygienic purity conditions. The completely assembled swab is then individually wrapped and the final product subjected to a special EtO sterilisation procedure developed by SARSTEDT to comply with the requirements of forensic analysis TO ensure the absence of DNA contamination. With a test procedure based on a detection limit of 0.5 pg DNA/μl extracted volume, absence of DNA is now guaranteed. A 73bp amplicon also enables the detection of partly degraded DNA (target gene: human cytochrome oxidase).
Apart from Forensic Swabs with polystyrene stem, our range also includes a wooden stem option. The Forensic Swab L has an extended handle for the hygienic collection of reference samples. The Forensic Swab XL with extended stem is ideal for the collection of evidence in sexual assault cases.
