Dual Swab Evidence Kit
Dual Swab Evidence Kit features two red and blue swabs enabling two-step wiping that clearly separates dry and mixed materials during evidence collection. The polyester fiber tips measure 4mm diameter with 12mm tip length on 75mm total length polypropylene shafts at 2.8-14mm diameter. Ethylene oxide sterilization ensures contamination-free collection. The rectangular sleeve prevents slipping during handling and provides easy storage without requiring separate evidence bags.
Large frosted surfaces on both sleeve sides accommodate writing for case documentation and chain-of-custody information. Visible sleeve sides allow direct viewing of evidence within without opening sealed packages. Anti-static material prevents DNA adsorption and minimizes trace evidence loss during collection and transport. The sleeve includes a built-in extraction liquid device for easy adjustment of water amount in swabs. The extraction liquid uses a patented, non-degradable formula that maintains DNA stability during evidence preservation periods.
Sexual assault investigation teams use the Dual Swab Evidence Kit during victim examinations to separate biological fluids from skin cells in two-step collection protocols. Military criminal investigation units apply it at assault scenes to document mixed biological evidence requiring sequential sampling. Naval medical facilities utilize the anti-static properties during shipboard evidence collection where static electricity interferes with trace material recovery. Aviation security personnel employ the dual-swab methodology to examine aircraft interiors for biological contamination requiring separate dry and moistened collection techniques.
Tactical Supply Pakistan supplies dual-swab collection systems that streamline evidence packaging by eliminating separate evidence bags, reducing storage requirements and simplifying chain-of-custody documentation for Pakistani forensic laboratories processing high-volume sexual assault and violent crime cases.
Can investigators write on the sleeve with standard ballpoint pens?
Yes, the frosted surface accepts ballpoint pen, permanent marker, and pencil writing. The material resists smudging and maintains legibility throughout evidence transport and storage without requiring adhesive labels.
