Wow Rex are fast now as the have a depot in the UK.

My 50ml addition funnels arrived this morning just a few days since I ordered them. Fast but inaccurate they are 19/26 not 24/29 joints.
They do have PTFE stopcocks., very nice I must say, should I get some 19/29 glass to go with them.

It will cost me more for an adapter or stopper than a funnel.

PS: excellent problem correction service after contacting them they have already refunded my costs.

I do have some PTFE blocks I wonder how hard it can be to turn and drill PTFE.

Borosilicate glass:
Good temperature resistance and good thermal shock resistance but finite.
For normal, standard service typically 200-230°C, for short-term (minutes) service max 400°C
Maximum thermal shock resistance is 160°C

I'm sure you could probably find a single 19/26 stopper and a 19-24 adapter for pretty cheap if you keep looking. It's not like you need one for every funnel.

I see they have changed the ad to 19/26 and the free post to £14.50. Sorry I guess you missed the original ad. Apparently they sold 22 so perhaps some other members got lucky. Thinking about it if its $20 post for four its still a good price if you want four and with PTFE stopcocks.
