Hard To Find Geological Standards!

We have recently obtained the standards inventory of a major defunct laboratory. Most of these materials are hard to find or no longer manufactured. They are perfect to add to your calibration curve and/or replenish the stocks of your company’s standards library.

All of these items are in good condition and are accompanied by the certificate of analysis. These standards are in limited quantities and are subject to prior sale.
