UN3373 検体バッグ：生物学的危険物質の安全な輸送の確保

In modern medicine and scientific research, the demand for the transportation of biological samples is increasing. These samples may contain pathogens or other hazardous materials, so their transportation must strictly comply with safety standards. The UN3373 specimen bag, designed specifically for transporting Class B biological hazardous materials, has become a key product in the field of biological sample transportation due to its excellent safety and compliance features.

Definition and Scope of Application of UN3373 Specimen Bags

Definition
The UN3373 specimen bag is a packaging standard established according to the United Nations’ “Regulations on the Transportation of Dangerous Goods,” specifically designed for transporting Class B biological hazardous materials. Class B biological hazardous materials include human or animal blood, tissues, excreta, and secretions, which may contain pathogens but have a relatively low level of infectivity.

Scope of Application
UN3373 compliant bags are widely used in medical diagnostics, clinical trials, scientific research projects, as well as the collection, storage, and transportation of biological samples.

Key Features of UN3373 Specimen Bags

Pressure Resistance
UN3373 specimen bags must be able to withstand an internal pressure of 95 kPa without leakage, even under extreme temperatures (from -40°C to +55°C).

Sealing and Puncture Resistance
The sealing system of the specimen bag is rigorously tested to effectively prevent gas and liquid leakage. Made from multi-layer composite materials, the bags are puncture-resistant.

Single-Use
To prevent cross-contamination, UN3373 specimen bags are typically single-use products. After use, they should be disposed of according to medical waste handling procedures to ensure the safety of the environment and personnel.

Marking and Labeling
The specimen bags are marked with the “Biohazard” symbol and include relevant transportation information and operating instructions. These markings and labels help remind transportation personnel and recipients to ensure safety and compliance during the transportation process.

Packaging Requirements for UN3373 Specimen Bags

According to the UN3373 standard, biological samples must be packaged in a three-layer structure:

• Primary Container: The container that directly holds the sample, such as a test tube or bottle, which is leak-proof.
• Secondary Packaging: The primary container is placed inside the secondary packaging, such as the UN3373 specimen bag, which provides additional protection.
• Outer Packaging: The secondary packaging is further placed in a sturdy outer package, such as a UN3373 biological sample box or an insulated container. The outer packaging must include the sender’s and recipient’s information, emergency contact details, and the UN3373 symbol.

Application Scenarios of UN3373 Specimen Bags

UN3373 specimen bags are widely used in the following fields:

• Medical Diagnostics: For transporting blood, tissue samples, etc., ensuring the samples remain intact until they reach the laboratory.
• Clinical Trials: Used in clinical trials to transport drugs, biological products, etc., ensuring the accuracy and safety of the trials.
• Scientific Research: For transporting microbiological media, environmental samples, etc., supporting the smooth progress of research work.
• Public Health: Used in disease control and prevention efforts to transport pathogenic microorganisms, preventing the spread of pathogens.

The Importance of UN3373 Specimen Bags

The use of UN3373 specimen safety bags ensures the safety of biological samples during transportation and complies with international transportation regulations. Through strict packaging and labeling, these bags effectively prevent sample leakage and cross-contamination, thus safeguarding the safety of transportation personnel and the environment. Moreover, the standardized design and single-use feature of UN3373 specimen bags significantly simplify the transportation and handling processes.
