Double-Ring Blood Collection Card (Enhanced)

Description

The Enhanced Double-Ring Blood Sample Collection Card is a high-performance single-card system designed for long-term DNA preservation and reliable blood sample collection. Made with imported database-grade collection paper, this card ensures DNA stability for over 17 years at room temperature, suitable for STR analysis. Each card is sterilized to prevent external contamination, with a liquid-proof inner membrane to avoid cross-contamination. The single-sample design allows multiple repeated tests, and all sample information can be recorded directly on the card cover for clarity. Integrated disposable sampling tools simplify collection.

Key Features:

• Imported database-grade collection paper, preserving DNA for 17+ years.

• Sterilized and specially treated to prevent external DNA contamination.

• Single-sample design avoids cross-contamination.

• Liquid-proof inner membrane prevents leakage and preserves sample integrity.

• Supports multiple repeated tests from one sample.

• Sample information can be recorded directly on the card cover.

• Integrated disposable sampling tools for convenient use.

Scope of Use:

• Forensic and criminal investigation blood collection.

• STR DNA analysis and paternity testing.

• Field or post-mortem blood sample collection.

• Long-term room temperature DNA storage and transport.

Technical Parameters:

• Packaging: 400 cards per box.

• Card type: Enhanced double-ring blood sample collection card.

• Sample volume per unit cell: 5–10 µL.

• Storage: Cool, dry, and ventilated environment.

• Included items: Single card with integrated sampling tools.

Usage Instructions:

1. Sampling: For live peripheral blood, directly touch or drop blood onto the card. For field or post-mortem blood, use a needle or cotton swab to evenly spread blood without overloading. Follow the card’s collection steps.

2. Storage: Air-dry the sample completely in a cool, dry place; do not seal in plastic while wet.

3. Extraction: Use small tweezers or scissors to remove individual cells. Each cell collects 5–10 µL of blood for DNA analysis.
