Biofiltration – The Stirred Cell Edition
ByAndreaIntroduction: The lab purchased an Amicon 8010 Stirred Cell which has a 25mm diameter for membranes and holds 10mL of solution. The device works by placing the solution into the cell, pressurizing the system at 8-10 psi, and creates stirring via an elevated stir bar and the stir platform. This type of filtration system was chosen…
Barcikowski Particles
The Barcikowski samples, sent from Germany a month ago, continue to be a fecund source of inconsistant data. Using the DLS to monitor several filtrations has resulted in a series of baffling results that I think I’ve finally begun to understand. First, the promising results: A DLS of Sample 1 (a mixture of bioconjugated gold…
W620: Mechanical Testing
The production crew recently delivered W620 to the lab, which was created to mimic W504 (and W612). W620 shows high burst pressure and has air permeability comparable to W504/612.
Cells Growth in Different Media
ByAslanThe goal of this set of experiments was to study the growth rate of cells in 3 different media; 1. Complete Media 2. Exosome Free Media 3. Serum Free Media. We studied the effect of media on both ADSCs and FBs. Cells growth was monitored by a Matlab code that Henry has made for us….
Cell Growth on pnc-Si
ByJimA couple of summers ago a Penn State summer student named Joe Fantuzo was working in the lab measuring cell growth rates and cell spreading on pnc-Si membranes and comparing the results to glass coverslips and tissue culture grade plastic. At least that is what we hired him to do. Joe spent much of that…
KMnO4 as a Platform: absorbance vs. concentration
ByJimI discussed with Jess the possibility of using a negatively charged dye. People did use such dyes before but we probably need to order them at this time. Since now we can use the spectrophotometer to determine the concentration of a solution, we might be able to make use of the potassium permanganate (KMnO4) solution…
