Shimadzu Aluminum Crimp Cap 20 mm 200 Caps

The Shimadzu 220-97331-06 Aluminum Crimp Cap is a laboratory consumable designed for securely sealing vials, particularly those used in analytical applications such as chromatography. This cap has a diameter of 20 mm, making it compatible with vials that have a 20 mm crimp-top finish.

Aluminum crimp caps provide a robust and leak-proof seal when applied with a crimping tool. The metal construction ensures a strong hold, preventing sample evaporation and contamination, which is crucial for maintaining sample integrity in sensitive analyses. These caps are commonly used with headspace vials for gas chromatography (GC) applications, as they can withstand the elevated temperatures and pressures involved in the headspace sampling process. The Shimadzu 220-97331-06 Aluminum Crimp Cap is an essential component for reliable sample containment in analytical laboratories.
