Key Features
-
Multi-sample compatibility: Works for blood, saliva, and semen without cross-contamination via labeled dual ends.
-
High absorbency: Flocked heads capture 30-50% more sample volume than standard cotton swabs.
-
Forensic-ready: Single-use, sterile packaging maintains sample integrity for DNA analysis.
-
Efficient workflow: Reduces tool count while handling multiple evidence types in one device.
Application Scope
-
Crime scenes: Homicides, sexual offenses, or assaults requiring blood, saliva, and semen sample collection.
-
Forensic labs: Processing multi-type biological evidence for DNA profiling and court admissibility.
