Gas mixing/blending

Submitted by Kyle Grice / DePaul University on Wed, 12/06/2017 - 08:19

Hi All,

I want to mix gases in several ratios for an experiment. In grad school we had a gas mixer to make the 5-10% H2 in N2 regen gas, but I haven't been able to find the model online. 

Does anyone have a gas mixer to measure the flow of two gases, and if so, what's the brand/item info? Any other ideas on how to mix gas flows? This would be with flowing gases, not a static amount of gases. 

Thanks!

Kyle

NMR parts

Submitted by Chip Nataro / Lafayette College on Mon, 12/04/2017 - 13:41

We are getting rid of our old JOEL Eclipse 400. It has a multinuclear probe, gradient shimming, temperature controller and auto-sampler. It is essentially good for parts. Is anyone interested? Let me know.

Research and Social Media

Hi All,

Has your research benefitted from social media (Besides VIPEr of course!)? Has anyone started a research collaboration over social media (Viper included, but I'm thinking of twitter, researchgate, etc)? I am looking for anecdotes to include in a workshop/talk about social media and professional development. I've got my stories already (Viper included!), but wanted to hear about others. 

Cheers,

Kyle

Cleaning lab coats

Submitted by Catherine / East Tennessee State University on Fri, 07/21/2017 - 10:18

How do people handle cleaning lab coats if their department/university doesn't have a cleaning service?  I'm not sure I'm comfortable with bringing lab coats home to wash, but I also don't want to have to throw out and replace dirty coats.

Cheap Digital Microscope?

Submitted by Kyle Grice / DePaul University on Fri, 11/18/2016 - 14:25

Hello,

Has anyone had luck with a cheap digital microscope? I mainly use microscopes to look for crystals to send off, but I would like to connect it to a computer (hence the digital part) so I can take a picture if I want to email to my crystallographer. 

Thanks!

Shelves for chemical storage

Submitted by Joanne Stewart / Hope College on Tue, 10/25/2016 - 09:41

Dear IONiC friends,

It is time for us to replace our shelves in our chemical storage room. Does anyone have any recommendations? We have a big store room, so cost will be a factor. But we of course want to be as safe as possible. Are lips necessary? What chemically-resistant surface do you have? (Yes, we have professionals on this, but this community always has great suggestions.)

Thanks,

Joanne

cheap O2 removal for glove box

Submitted by Tim Herzog / Weber State University on Mon, 05/16/2016 - 16:45

I've been trying to get an old glove box working better and came accross a cool new option from Vac atmospheres for O2 removal.  They now sell activated cartridges for a couple hundred bucks each that contain an already active copper catalyst for O2 removal.  For about 2k, you can buy a little blower that the cartridge mounts to and turn any air tight chamber into a glove box.  For me, the economics will work out better than maintaining the specialty gas cylinder required for regeneration.

Unusual and Humorous Results

Submitted by Clifford Rossiter / SUNY Potsdam on Tue, 10/06/2015 - 13:45

A research student (Nicole Stephens) walks into my office and asks me to look at her TLC plate. Upon looking under the UV light I burst out laughing. I have never seen a TLC like this before and wanted to share the joy. Please feel free to share any humorous anecdotes with fellow Vipers.
