While BASIK™ brand screw caps are not designed for ion chromatography, they may work for some applications. But I would not use them sensitive methods.
We do suggest it might be worthwhile for maximum performance in IC to use our ultra-pure polyethylene screw caps, see image below.
Note that these caps, are a single use cap and will not reseal after injection.
