Batching could significantly decrease the sensitivity on the Sentinel EAD process, and wouldn't allow Charles River to deliver the level of diagnostics envisioned and demanded via the research community.

We just purchased a fresh Trane furnace with A/C. Your fellas were really professional, did an incredible occupation and had been a pleasure to acquire in our property.
