Specifications
The Thermo Scientific Seal Red Crimp Top W/TEF PK100 C4011-98R Seal Red Crimp Top W/TEF PK100 are specifically designed for 11mm crimp-top vials, a standard size in many analytical laboratories, fitting 12x32mm vials. The primary construction involves an aluminum seal, providing a rigid and durable outer shell. This aluminum body is crucial for maintaining the seal’s shape and ensuring it crimps securely onto the vial neck.
The septum itself is a critical component, featuring a combination of PTFE/Red Rubber. The red rubber offers medium durometer, contributing to a good balance between flexibility and firmness, which aids in achieving a reliable seal. This is layered with a 15mil layer of clear PTFE, known for its exceptional chemical inertness.
These specifications matter immensely for sample integrity. The aluminum seal ensures a robust closure, while the PTFE/Red Rubber septum provides a barrier against a wide range of chemicals, preventing sample contamination or solvent evaporation. The 15mil PTFE layer is particularly important for handling aggressive solvents or sensitive analytes that can be compromised by less inert materials. The designation of “Red” in the product name refers to the color of the rubber septum, often a visual indicator of its material composition and durometer. The “PK100” signifies that each package contains 100 seals.
Performance & Functionality
In terms of performance, the Thermo Scientific Seal Red Crimp Top W/TEF PK100 C4011-98R Seal Red Crimp Top W/TEF PK100 performs its primary function exceptionally well: sealing vials to protect their contents.
