disposable virus sampling tube

A disposable virus sampling tube is a sterile, single-use container designed for the collection, preservation, and transport of viral specimens (e.g., nasopharyngeal swabs, oropharyngeal swabs, or other biological samples). These tubes are essential in diagnostics, particularly for detecting pathogens like SARS-CoV-2 (COVID-19), influenza, RSV, and other viruses.

Key Features:

1. Sterile & Disposable
   • Pre-sterilized to prevent contamination.
   • Single-use to avoid cross-infection.
2. Viral Transport Medium (VTM/VTM)
   • Contains a solution (usually liquid or gel-based) to preserve viral RNA/DNA integrity.
   • Common components:
     • Hank’s Balanced Salt Solution (HBSS)
     • Antimicrobial agents (e.g., gentamicin, amphotericin B) to prevent bacterial/fungal growth.
     • Protein stabilizers (e.g., bovine serum albumin).
3. Leak-proof Design
   • Secure screw cap or snap cap to prevent spills during transport.
4. Compatibility
   • Works with PCR, RT-PCR, antigen tests, and viral culture.
   • Compatible with swabs (flocked, rayon, or polyester).
5. Labeling Area
   • Space for patient ID/barcode labeling.
6. Temperature Stability
   • Some tubes can stabilize samples at room temperature (2–8°C for short-term, -70°C for long-term storage).

Common Types:

• Standard VTM Tube – Liquid-based medium for swab storage.
• Inactivated Virus Tube – Contains lysis buffer to immediately inactivate the virus (safer for lab handling).
• Dry Swab Tube – No liquid medium; used for direct PCR testing.

Usage Steps:

1. Collect sample (e.g., nasal/throat swab).
2. Break or cut the swab stick and place it into the tube.
3. Secure the cap and label the tube.
4. Transport to the lab under recommended conditions.

Applications:

• COVID-19 testing
• Influenza & RSV detection
• Research & epidemiological studies

Regulations & Standards:

• FDA/CE/ISO certified for quality assurance.
• Complies with WHO and CDC guidelines.
