Use Borosilicate Chemical Storage Bottle with GL45 Thread as Reaction Flask?
these Borosilicate Chemical Storage Bottle with GL45 Thread are
easily available and seem to be quite sturdy.
could you take a GL45 Cap,
drill a hole and place a
NS adapter on top of the GL45cap
at the bottom of the GL45cap is the screw thread of the NS adapter
which can be wrapped around with some teflon and screwed
down with a smaller GL20 cap upside down with a hole drilled in it.
use it for anything up to ~150C
these GL45 caps come with teflon inserts.
maybe drill 1 or 2 additional holes add a hose adapter
for liquid additions.
would this work safely or is there a better way?

I have seen them used such way in various applications, including gas washing or bubbling.

when using 29/32 NS and x liters of volume.
what minimal diameter in centimeters
should be there as an opening hole for the distillation head ?
cause the vapor needs space to go through.
cause these glass adapters with screw end have different diameters...
not sure which one would be suited if you do a simple distillation
of a solvent for example 2 liters.
what diameter is required min?

Looking at the very wide range of caps Duran makes I dont see why not.
My next gas washing bottle is from Duran Schott. I know they have caps that accomodate overhead stirrers and even some of their bottles seem to be
designed for more than just holding a liquid.

Sohxlet has very narrow channel for vapors to travel. The diameter effects mostly on flow kinetics and it's not that important in batch-wise mini
scale operations. Biggest issue is choking by condensed liquid, which will cause uneven boiling, fraction separation and other issues and could
hypothetically build pressure in the apparatus. If the distillate could solidify in any circumstances, then the issue would be gravely pronounced.
Hence nothing prevents you from using for example 8mm PTFE tubing for distillation vapor transfer.
But for the matter, I don't see use for storage bottles because jointed glassware is dirt cheap and sources from China and eastern europe supply
multi-liter flasks with multiple necks in all major nominations starting from few dozen bucks a piece.

I have used sealed 100 ml media bottles as reaction vessele, but I never tried to distill or other function in them. That seems overly complex. If
you just need to run a reaction at a set temperature, I just put the bottles into a bath or oven in a holder and as long as they are sealed, not
generating pressure, and the temp is not much above the BP of the solvent, they work fine. i used to do multiple reactions that way when I was
trying to do high throughput chemistry. I also used various vials and test tubes for small reactions as well.

The lids can be changed to have a hole with a silicon teflon seal. Making an adapter to connect to joints isn't hard. Media bottles are generally
rugged, and provided you account for the fact a flat bottom won't handle heat gradients and pressure the way a round bottom will, you have a
convenient reaction flask at hand.
