The Whitesides Chamber implemented in the McGrath Lab has now successfully generated a steady and linear gradient
ByHenry September 28, 2009

Hi all, After nearly a month of troubleshooting the fabrication of Whitesides Chamber we finally have the capability to generate a steady and linear gradient of molecules. In the presented case, we have generated a gradient of rhodamine 6G (R6G), which is a fluorophore that allows us to visualize and confirm the existence of the…

Membrane Anneal Study: W510X, W600 Testing
ByKarl Reisig June 26, 2008

I recently tested W510X and W600 described by Dave here for air permeability, rhodamine diffusion, and burst pressure. No air permeability was observed; even a sample with one very small pinhole (W600 800C anneal) only had a permeability of 11 cc/atm*cm2*s. To verify the lack of pores I performed rhodamine diffusion on the W600 700C…
