Cotton Swabs, (box/100 two swab envelopes)

With the advent of new, faster, more precise DNA testing, collecting evidence such as blood and body fluids from crime scenes has become even more important than before. This evidence must be collected properly for accurate test results.

If the blood stain is damp, dab one sterile cotton swabs on the stain. If the stain is dry, wet the swab with distilled water and dab on the stain. Wet a second swab with distilled water and swab the background surface near the stain without touching the stain. The second swab is used to determine if any contaminants may be on the background. At the end of the collection process, also wet two swabs with distilled water only. This is a control sample to show that your distilled water did not contain any contaminants.

Once you get them back to your office, you must dry the swabs before packaging. Here is a swab dryer, a case for carrying the swabs from the crime scene and packages of sterile cotton swabs. The Swab Dryer is 8" W x 13.5" L x 8.5" H. The rack inside holds 18 swabs at one time. There are nonskid feet on the bottom for placing the dryer on a counter and two key hole attachments on the back, for mounting. A timer comes with the dryer so you are reminded to take the swabs out. The Rack and Carrying Case is used to transport the swabs from the crime scene to your office in a clean container.
