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 a Nylon tip attachment. The evidence surface is wetted with buffer. Cells are collected on the surface of the Nylon tip, while solubilized DNA is collected inside the tip. When the sample has been collected the tip is replaced into the provided DataMatrix labeled vial. Once the tip and vial are received at the lab they are processed using standard laboratory procedures. The tip requires no cutting and is inert to all extraction buffers.
该系统旨在支持从Touch DNA到干血，液体，粉末和纤维的各种证据收集要求。TED系统集成了一个手持式真空设备，该设备带有专门设计用于收集适当证据的不同末端附件。证据收集在小瓶中，准备用于实验室处理，以最大程度地减少人工操作。使用尼龙尖端附件从不同的表面捕获触摸式DNA样品。证据表面被缓冲液弄湿。细胞被收集在尼龙尖端的表面，而溶解的DNA则被收集在尖端内部。收集样品后，将尖端替换为提供的带标签的DataMatrix小瓶。在实验室收到吸头和小瓶后，将使用标准实验室程序对其进行处理。尖端无需切割，并且对所有提取缓冲液均呈惰性。
