So I am now gradually clearing old samples, some of them 20 years old, out of the #glovebox. I had kind of assumed that they were mostly dead.
Not quite. A few grams of brown NaMeCp caught fire after 5 or 6 minutes in air. And two samples of K4Si4 went off with a flash/bang when I dropped them into a wet beaker. More are waiting. #yikes

Depressing to think of the embodied emissions, but at least no one else has to deal with the surprises in future… #chemistry #academiclife #shitejihad

The atmosphere is now as good as I've seen it in years. There's bit of a white film on the window that needs wiping off and ancient samples that I don't suppose I'll ever use again.
Once we've done our shite jihad I suspect that my #glovebox will be good to go for another decade or two - I've seen second hand microprocessor controllers on eBay and relays, fuses and so on are easy. Someone will inherit an old but solidly working box when I go.
So quick, let's get some #chemistry done. 2/2

And so my #glovebox is is undead!! Atmosphere well below 5 ppm of oxygen. Now the cleanup begins.

The spots are a very sensitive organometallic compound used as an indicator. Green is good. Orange is baaaaaad. #chemistry #academiclife

#GloveBox Saga. So the regeneration cycle is on for the catalyst on my #glovebox. Because I'm out of town I've got a couple of students primed to take photographs of solenoid valves to see whether the lights go on in the right order and whether when VRE opens the gas actually flow. If the light is on but gas doesn't flow then it's back to ordering another replacement part. How many weeks might that take? #sigh #chemistry #academiclife

I return to my #glovebox to discover that the catalyst heated but the gas did not flow through at all - the flow rate seemed correctly set at the start. Does this mean that there's a deeper problem still lurking?

A whole day wasted. I'll have to try again tomorrow. Fingers crossed.

#Glovebox purged with 100 bar (7 m3 of nitrogen). Now the catalyst is heating up waiting for its nitrogen/hydrogen feed to reduce it down and activate it. We might have a working box by morning.

And then the shite jihad will begin. Time to clear out a lot of ancient samples and abandoned schlenks. There's a fair bit of rather manky white phosphorus and alkali metal in there so there may be some fun to be had…  #chemistry #academiclife

After multiple vicissitudes the correct replacement circuit breaker for my #glovebox has finally arrived. When it was installed, the blower that runs the recirculation in my glove box came back to life. 🍾🍾🍾 So now I need to purge the box with a cylinder of nitrogen and regenerate the catalyst which I have completely replaced. It's been a 2 ½ month emotional roller coaster. Fingers crossed we'll have the atmosphere down around 5 ppm O2 before the end of the week. #chemistry #academiclife

@seventeenmagpie I don't know. I'm utterly baffled. The computer that controls the box got itself into a state where it just heated the crap out of the catalyst while circulating the box. That should be impossible but somehow something or someone got it into that state.
I've got new catalyst in there. But that's when the pipework must have cracked. And now something else is misbehaving… #sigh #glovebox

Could be a tamper to with the #carbattery, or some that the #carradio pings You for #unlockcode😏!
#HakunaMatata🤷, look around #glovebox or wherever about within, #inshaAllah, U could find #lockpin to #doityourself #mwenyewe!

Cleaning out my glove box, I found my Google Maps beta version 1.0 from 2003. It didn't zoom very well, but it worked great when I had a weak signal.
