Product Description

The Chromatography screw cap 10ml is a precision-engineered closure designed for headspace vial applications, featuring a threaded screw design compatible with 10ml GC headspace vials. Constructed with PTFE/silicone septa, these Headspace vial screw caps ensure leak-proof sealing for volatile compound analysis in GC or HPLC systems. The caps operate reliably across temperatures from -20°C to 120°C and withstand autoclaving at 121°C. Ideal for pharmaceutical, environmental, or food testing industries, the 10ml GC headspace caps offer chemical resistance and consistent performance in automated samplers. Key advantages include enhanced sealing integrity, reduced vapor loss, and compatibility with standard crimpers. Potential drawbacks include septa degradation after repeated punctures. Color-coded rings simplify batch identification.
