“Reverse” centrifuge seperations
Back in November we were visited by Tom Berkelman of BioRad to see if he could use our NPN membranes to successfully separate some proprietary nanoparticles from IgG in a solvent with secret ingredients. These particles have an interesting absorbance spectrum as well as strong fluorescence. During that visit and in subsequent separations in the…
W415-T and W416-T: Air Permeability and Burst Pressures
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…
Experimental Validation of the ECMO Model
Two of my recent posts have dealt with my efforts to model ECMO and to experimentally validate this model. This post will describe the key change I made to my experimental system since my last post and describe my efforts to recreate the experimental results with my model — successfully! In an turn of extraordinary…

SepCon Permeability Tests
This is some really preliminary data that I hope to add to in the next couple of days. Yesterday I prepared 4 SepCon samples from wafer 310. I spun them at 3.3 psi for 2 hours with just PBS. I recorded the permeability, and then performed the exact same test with 3mg/mL protein in the…
Karl’s Thesis
Hey all, Here’s my thesis: ksmith thesis I filmed the public portion of my defense and posted the video to youtube. I’m not leaving till the end of the week, and I’ll be back for a week in mid-May as well as being generally around Rochester this summer (this isn’t goodbye!) but my permanent email address…
