BioTX’s patent pending TED evidence collection system is designed to support a variety of evidence collection requirements from Touch DNA to dried blood, liquids, powders, and fibers. The TED system incorporates a hand held vacuum device with different end attachments specifically designed for the appropriate evidence to be collected. The evidence is collected in vials ready for lab processing to minimize manual handling. Touch DNA samples are captured from different surfaces using the nib attachment. The evidence surface is wetted with buffer. Cells are collected on the surface of the nib, while solubilized DNA is collected in the vial. When the sample has been collected the nib is placed in a labeled vial and the liquid vial is detached and labeled for transportation to the lab. Once the nib and vial are received at the lab they are processed using standard laboratory procedures. The nib requires no cutting and is inert to all extraction buffers.
