Biological sample collection and storage sleeve

Description

The Biological Sample Collection & Preservation Tube integrates sample collection, rapid drying, preservation, and labeling in a single device. It uses physical sealing and layered rapid-drying technology to quickly absorb moisture from samples, combined with solid anti-mold agents to prevent decay, odor, and contamination. The tube’s cotton swab tip is designed for micro-sample concentration, enabling direct DNA extraction and amplification, which reduces lab costs and increases efficiency. Transparent construction and suspended swab placement allow visual inspection and prevent contamination or sample loss. This system increases micro-DNA collection efficiency by approximately 1.8× compared to traditional swabs and paper storage. It is suitable for wet or dry samples, including traces from fingernails, handles, and other small surfaces. Long-term studies show samples remain preserved for over 2 years at room temperature, with potential preservation up to 20 years. The tube also includes label paper for clear sample identification and optional sealing.

Key Features:

• Prevents sample decay, mold, and odor through rapid-drying and anti-mold technology
