I recently tested intact samples from W415-T and W416-T. All samples from W415-T were completely intact except the one located 3.167 units from center, which had one medium pinhole. All samples from W416-T were intact, but a few had irregular membrane shape, one with constant area and two with about +5% membrane area. I thought…
Below is an image of HUVEC grown on RTP treated W303 for 72 hours. The cells were seeded at high density and therefore reached confluence prior to day 3. The first row shows the membrane area of the sample; the membrane is not intact. The second row shows the edge of the sample. Live and…
Transferred from other blog… Wafers 398 and 418 were recently tested for burst pressure. Wafer 398 had a burst pressure range of 4.28-8.24 psi, with the great majority of intact membranes on the wafer having no or one tiny pinhole. When removing samples from this wafer more shards than usual were created, with some fragments…
