SafTPak Reusable Secondary Pressure Vessel with Lid 1.25 L Total of 6 Containers.

SafTPak 35154 STP-104R Reusable Secondary Pressure Vessel – 1.25 L

The SafTPak 35154 (Model STP-104R) is an industry-standard secondary pressure receptacle engineered to ensure the absolute containment of hazardous biological specimens during transit. Built from heavy-duty polypropylene, this 1.25-liter vessel is designed to hold primary sample containers (such as blood tubes, vials, and culture swabs) alongside necessary absorbent materials. It features a highly visible orange screw-cap lid equipped with a specialized O-ring gasket, creating an airtight and leak-proof seal capable of withstanding the severe pressure differentials experienced during high-altitude air transport. Because it is fully reusable and easy to decontaminate, the STP-104R offers an economical and environmentally conscious solution for diagnostic laboratories, clinical research organizations, and public health networks conducting continuous, high-volume specimen transport under strict UN 2814, UN 2900, or UN 3373 compliance guidelines.

Technical Performance and Design

• High-Pressure Containment: Engineered to consistently withstand 95 kPa internal pressure differentials, preventing sample leakage during flight or in the event of severe physical impact.

• Durable Polypropylene Construction: The robust polymer body provides excellent resistance to physical shock and chemical exposure, ensuring the vessel maintains its structural integrity over years of repeated use.

• Secure O-Ring Seal: The high-visibility orange lid is equipped with a resilient gasket that creates an impenetrable barrier against liquid bypass once properly threaded and tightened.

• Large 1.25 L Capacity: The wide-mouth architecture offers a generous internal volume, allowing for the rapid loading and unloading of multiple primary sample racks and cushioning materials without snagging.
