We arrange the shipment of commercial standards purchased from Absolute Standards, a standards manufacturer based in Hamden, CT, USA. 

We arrange the shipment only after you receive all your HPLC packages.

Commercial standards are shipped by Fedex overnight priority. The package is shipped via cold chain with samples kept on ice and it costs ca. USD 150-200 in shipping costs, hence it is important to receive the standards at the earliest and store in a freezer.
