Quick-Dry Swabs for Biological Evidence

Description

The TECS1506 swab is specifically developed for forensic collection of blood stains, saliva stains, semen stains, and other biological evidence. Each swab is housed in a transparent tube with a built-in high-absorption desiccant placed within 10 mm of the swab tip, actively absorbing moisture to prevent bacterial, fungal, and DNase activity that can degrade DNA. The swab head is suspended in the tube, enabling rapid drying without contact with surfaces, while the sealed tube protects the sample from external contamination. The cotton swab shaft is made of breakable material, allowing the swab head to be directly transferred into a centrifuge tube without scissors or tweezers, minimizing contamination. Each swab is independently packaged, and 100 swabs are included per box (5 packs of 20).

Key Features:

• Built-in high-absorption desiccant for rapid moisture removal

• Suspended swab head allows fast drying and prevents mold

• Transparent tube for easy visual inspection of collected evidence

• Pure cotton tip, produced under strict contamination-free conditions

• Breakable shaft for safe transfer into lab tubes

• Reduces DNA degradation during transport and storage

Application Range:

• Forensic collection of blood, saliva, semen, and other biological evidence

• Field DNA sample preservation and transport

• Long-term storage of trace biological evidence

• Laboratory DNA extraction and analysis

Specifications / Parameters:

• Swab total length: ≤110 mm

• Tube: Transparent with desiccant

• Desiccant placement: ≤10 mm from swab tip

• Swab material: Pure cotton

• Shaft material: Breakable safe material

• Packaging: Individually packed, 20 swabs per pack, 5 packs per box (100 swabs/box)

• Usage: Swab dry evidence directly, wet swab with 2–3 drops ultrapure water if needed

Usage Instructions:

1. Remove the tube cap and moisten swab tip if collecting dry samples.

2. Collect evidence by swabbing the target area.

3. Mark the swab with a pen to indicate the sampled region.

4. Replace the tube cap and record sampling information.

5. Transport and store under sealed conditions for DNA extraction.
