The Thermo Scientific Seal Blu Crimp Top W/TEF PK100 C4011-98B Seal Blu Crimp Top W/TEF PK100 is engineered with precision for critical sample containment. It features an 11mm aluminum seal, designed to fit standard 12x32mm crimp-top vials. The core of its sealing capability lies in the PTFE/Red Rubber Septum.
This septum is constructed with a medium durometer red rubber base, providing a flexible yet durable sealing layer. Encasing this is a 15mil layer of clear PTFE (Polytetrafluoroethylene). The aluminum top ensures a secure crimp, while the combination of materials in the septum is key to its performance.
These specifications are crucial because they directly impact sample integrity and experimental outcomes. The 11mm size and crimp-top compatibility ensure broad application with common laboratory glassware. The aluminum construction offers mechanical strength and a reliable closure.
The PTFE/Red Rubber Septum is where the real magic happens. The red rubber provides good elasticity and sealing pressure, crucial for preventing leaks. The 15mil PTFE layer, known for its exceptional chemical inertness and low coefficient of friction, protects the sample from contamination and ensures that the septum itself does not react with the sample or the injection needle. This material combination is designed to offer moderate resealability, making it suitable for single injection applications where an extra layer of confidence is needed, or for workflows requiring limited re-access.
Performance & Functionality
In practice, the Thermo Scientific Seal Blu Crimp Top W/TEF PK100 C4011-98B Seal Blu Crimp Top W/TEF PK100 performs its intended function with remarkable effectiveness. The primary job of containing samples is executed flawlessly, with no instances of leakage or evaporation during my testing period.
