20mm crimp cap

The 20mm Caps with Septa are specifically designed for secure sealing and precise analysis of headspace samples in laboratory settings. These caps have a 20mm diameter, ensuring a tight and reliable fit on crimp headspace vials. The septa, made of high-quality materials, provide excellent sample integrity by preventing contamination and evaporation during storage and analysis.

Teflon and silicone rubber or ultra-pure silicone are used as raw materials to ensure that the septa are non-toxic; to ensure excellent functions, it is particularly suitable for gas chromatography, and to ensure that the septum does not fall into the sample vial during the injection process;

20mm Crimp neck with 6ml, 10ml, and 20ml hold-up volume. Available in flat or rounded bottom designs for accurate instrument compatibility. Pre-assembled 20 mm crimp caps with septa are ready to use with any headspace crimp top vials.

There are two types of packaging for 20mm Crimp Top Closures produced by Aijiren, one is packaged in plastic bags, the other is packaged in threaded plastic cans, and the quantity is 100 per bag/can. Aijiren is packaged in cans. Because 20mm Crimp Top Closures are easily squeezed and deformed during transportation, which affects the sealing effect in the experiment, they are packed in cans.
