SwabShield™ has multiple holes in the sides and an open top to increase the airflow around the swab affecting the rate of drying.  Dry samples are less likely to deteriorate.*

SwabShield™ protects the sample from contamination by a physical barrier around it so it cannot touch other samples.
 

SwabShield™ has two sides suitable for writing identifying markings. This prevents the samples from becoming mixed in the field or in the laboratory.
 

SwabShield™ protects the sample from transfer to the sides of the envelope by putting a physical barrier between the sample and the envelope.

* SwabShield™ is designed to allow the sample to be placed directly into an evidence envelope.  It will dry in the envelope, however, use of an airflow will improve the drying time. The swab should be left in the SwabShield™ for drying.
