MSQ Caps for Low Adsorption Vials

We recommend using LA vials with our new MRQ polypropylene cap/PTFE silicone septa. This cap and septa combination was purposely designed for use with mass spectrometry. It shows little to no background contamination when compared to other cap and septa products in the marketplace.
