DNA collection flocking swab (with tube and vent)

Description

The HXZR-I swab utilizes nylon flocking technology, with short vertical fibers on the tip that prevent DNA cells from dispersing or being trapped in the swab, enabling rapid and efficient elution. Each swab features a breakable shaft for automated extraction workflows and is housed in a transparent PP tube with a vent at the top to allow moisture evaporation, preserving sample integrity. Sterilized with ethylene oxide in a cleanroom, the swabs are free of residual DNA prior to use. The kit includes 20 swabs and 2 bottles of distilled water extraction solution per pack, with individual dialysis paper packaging for labeling and traceability.

Key Features:

• Nylon flocked tip for high-efficiency DNA collection and elution

• Breakable shaft for automated extraction systems

• Transparent PP vented tube prevents sample degradation

• Ethylene oxide sterilized to eliminate residual DNA

• Dialysis paper packaging for labeling and sample traceability

• Moisture evaporates through vent to protect biological evidence

Application Range:

• Forensic DNA collection from stains or surfaces

• Collection and transport of trace biological evidence

• Laboratory DNA extraction and analysis

• Preservation of micro-scale biological samples

• Shaft diameter: 2.5 mm

• Break point distance: 30 mm from tip

• Swab total length: 107 mm

• Tube length: 110 mm, outer diameter: 13 mm

• Packaging: 180 × 45 mm dialysis paper bag

• Swab head material: Nylon; shaft: ABS

• Tube material: PP

• Kit contents: 20 flocked swabs + 2 extraction solution bottles per pack

Usage Instructions:

1. Open the packaging and remove the swab with tube; remove the tube.

2. Spray the swab tip with extraction solution to moisten.

3. Wipe the target stain or trace evidence.

4. Reinstall the tube; moisture will evaporate through the vent.

5. Place the swab with tube back into the dialysis bag and label with sample info.

6. In the lab, break the swab at the break point; leave the tip in the tube for extraction.
