    Nitrogen Gas Generator

    I've taken a little different approach. After months and months of disappointment looking for a supplier, I turned my hopes to ebay. eventually a 20kg CMS 240 appeared on eBay for a reasonable price (~$200 + $50 shipping) appeared.

    just got (finally) 20kg of CMS-240 for a psa nitrogen generator. if you had to do it again, anything you'd change? ie pressure level for the beds etc? I'm thinking of repurposing a dead oxygen concentrator to change the bed to CMS. Any suggestions?Any new projects ahead or is the OR and real life getting in the way?

    the spent gas is 'enriched' it is not particularly concentratedso, no - it won't work

    Low-Cost Research Glove Box

    this is a nice project but i think you've missed an important part. A glove box traditionally is +ve pressure with an inert atmosphere ie nitrogen gas. Similarly, the side tunnel serves to allow the transfer of items from atmospheric conditions to the inert glove box. there needs to be a second door that seals the main box when the side tunnel is open (and only opens after the tunnel is purged. On a side note, can you please detail the salt solution humidity regulation system? I'm not familiar with the setup.ThanksDoug

    flash powder

    for the record, I'm a chemist and a physician. No particulate is especially good to inhale HOWEVER, hard rock miners used to get aluminum inhalation therapy to treat silicosis. Aluminum dust is a pulmonary irritant. While I've heard of asbestosis and silicosis, we didn't get much training on the dangers of "aluminosis". ?There is a lot that is unknown in the world of occupational health and welfare. That being said, there is no capris on between inhaling asbestos and inhaling aluminum powder. Where did you ever get such an idea?

  • Slow Cooking Beef Short Ribs

    If you're interested in something different - texture-wise, try short ribs sous vide.I had twice braised Kalbi style short ribs at Allan Wongs in Hawaii. They were brilliant! I tried to duplicate this using a 48 hr cooking time at 52C. Briefly seared before going in, they were beautiful. I finished them with a reduction of the marinade and broiled them for 10 minutes to firm up the glaze. Mouthwatering and sooooo easy to do. Well worth the effort. Nitrous

  • Slow Cooking Beef Short Ribs

    Is it my imagination, or did you use boneless short ribs at one point in the photos?When you braise your ribs, wouldn't you typically use a lower temperature? 350F will boil the braising liquid - not really your intent here, is it?Otherwise, a nice instructable!thanks
