Submit Samples

4/12/24 - Orders requiring polished sections are currently delayed due to an interruption in our resin supply. Based on our supplier’s delivery estimate, we project that polished section orders will resume shipping in mid- to late June.

Orders submitted in the meantime will be prepared for immediate embedding upon receipt of resin. Thank you for your patience!

Unpolished sections (optical use only) are unaffected and can be completed at normal and rush turnarounds.
