Hi everybody, I’m going to be trying some new things soon using hexane and pentane and I don’t have a fume Hood. I’d like to get myself a proper respirator to protect against these solvents specifically and more preferably. I did a search and did not find anybody talking about it here. I hope y’all are staying safe. What cartridgs/specs do we need to stay safe in this business? Pentane looks expensive so I’d like to find how to put together an inexpensive condenser setup I could use for crystallization. Any leads on that would be appreciated too.
The scale at which you are playing with pentane and the vessel in which you play affect the style of condenser.
If you’ve got jacketed stainless reactor, or even a an old CLS base lying around you might use one of the condensers Glacier Tanks now sell
If you’re using the boiling flask from your SPD you might find a reflux condenser on eBay that plugs right in.
Maybe start here?

Thanks for that condenser link. Good info there. I don’t have access to that ppe link. Just using a 5 L roto right now. No cls or spd. I haven’t bought anything specifically for crystallization yet, I suppose a jacketed stirred reacter with condenser is best and an open air pyrex dish on a shelf is the low tech way. I was thinking of using my roto to warm the Pentane and dissolve extract, but I don’t want to tie it up through the whole crystallization process. I’m very small scale I’d like a 1 or 2L batch size.
