Permeance tests with new Omega rotameter
Yaron has acquired an Omega rotameter (FL-3803ST) with interchangeable flow tubes. The tubes operate in three different ranges low (6-61 mL/min, 042-15-N), medium (150-1,682 mL/min, 082-03-N), and High (1,000-23,752 mL/min, 034-39-N). I’ve attached an excel file with the calibration data…
SOP for bonding of PDMS to NPN
I’ve written a quick SOP document reflecting the procedure that resulting in successful permanent PDMS-NPN bonding. The procedure described in this document has not been optimized and may include unnecessary or otherwise sub-optimal steps. These steps reflect the steps that WERE…

Small Animal Model Hemodialysis Set-Up
Sprague-Dawley rats will be purchased from Harlan. These pre-manipulated animals will have been catheterized prior to shipment. We will feed them an adenine rich diet to induce uremia, high levels of urea in the blood. Once uremic, a rat will…
Schematic of Long Term Clearance Test Setup.
This is the setup used for the long term clearance testing. The fraction collector can be set to advance to the next collection tube at set intervals from 1 min to 99 min. I am currently conducting an evaporation test…
