Another thinking-out-loud post.<\/p>\n\n\n\n
I have inherited a 500mL round bottom flask and heating mantle from my lab. I’m trying to see what I would need to make it into an essential oil still.<\/p>\n\n\n\n
Option 1 is the cheapest<\/p>\n\n\n\n
Total: \u20ac46.97<\/p>\n\n\n\n
Same but 1 size down<\/p>\n\n\n\n
Total: \u20ac37.05<\/p>\n\n\n\n
Same but 2 sizes down again, needs adapter<\/p>\n\n\n\n
Total: \u20ac47.40<\/p>\n\n\n\n
This one is the most simple option; a reflux separator with a condenser, straight onto the flask.<\/p>\n\n\n\n
Total: <\/p>\n\n\n\n
Same as before but reduced to 24\/29, i.e. thinner separator & column<\/p>\n\n\n\n
Total: \u20ac56.60 (200 mm) \/ \u20ac65.67 (300 mm) \/ \u20ac67.76 (400 mm)<\/p>\n\n\n\n
Same as before but reduced to 19\/26, i.e. thinner separator & column<\/p>\n\n\n\n

This one is the maximum I can do with my 500 mL heating mantle, although I could possibly fit a 2L chromatography flask too. Total: <\/p>\n\n\n\n Putting a stopcock between the boiling flask and the reservoir is a bad idea. It’ll clog up with plant material. Also, I want the biggest diameter reservoir opening possible, to make it easier to fill\/empty\/clean.<\/p>\n\n\n\n Ok I’ve decided I want the 5mL graduated 24\/29 Clevenger and a Dimroth on top of it, but I think I can get away with a shorter 200mm one because of the low heating power and high efficiency of the condenser. I can ramp up the coolant pump if needed, or just add another condenser on top if it turns out to be too short.<\/p>\n\n\n\n Total: \u20ac109.80 (dual with stopper) or \u20ac107.37 (single, no stopper)<\/p>\n\n\n\n What would a 2L biomass flask cost?<\/p>\n\n\n\n Total: \u20ac126.56<\/p>\n\n\n\n What about the one with a bigger mouth?<\/p>\n\n\n\n Total: \u20ac130.70<\/p>\n\n\n\n I’ve bought a Clevenger (5mL graduated, 24\/29 connections). <\/p>\n\n\n\n I’ll try to connect everything I already have up first. But none of those things are made to connect. There are 4 places that I’d like to be mostly “steam tight”:<\/p>\n\n\n\n To be continued.<\/p>\n","protected":false},"excerpt":{"rendered":" Another thinking-out-loud post.
