Construction of a Rotovap/Bump trap, in lathe.

[@birtday6326]

Wow. Great videos by a master. Cool to see how the stuff I use is made. No wonder its so expensive. Could sure use one of those bump traps.

[@willowandt]

This is a great simple way well done i see ppl do them on the bench ....not me lathe man,

[@loganathan1490]

Excellent work

[@dans5595]

when i was a chemistry grad student in the '80s, i loved glass blowing at the bench. simple stuff; ampules, cold traps, in situ vac line mods, side arms, etc. i would love to return to it at a higher level as a retirement job. any advice?

Thanks for sharing!

[@dustinbodie5675]

you're pretty damn good dude! wish i had someone like you teaching me.

[@ktfords]

+Dustin Bodendorfer thanks! Glad you enjoyed.

[@ktfords]

Thanks Dustin!

[@andrewaldrich3602]

Really interesting process. I wish I was allowed to use the lathe in my school's glass blowing shop

[@bigredinfinity3126]

Your school had a labglass shop wow we didn't even have decent flasks and most condensers were stolen

[@gabrielfelix1481]

there is no reason to build such a small piece on the lathe

[@028healey]

@@gabrielfelix1481 there are numerous reason!

[@hassanhanafe6644]

Wonderful work brother

[@jeremybutt9281]

Amazing craftsmanship!. Loved it.

[@grendelum]

I have no idea what you just made but damn you've got skill !!!

[@ktfords]

+orion khan Thank you!

[@grendelum]

Kevin Teaford - the one time I worked with glass in chem 101 I burned the dren out of myself (hot glass looks just like cold glass)... my lab partner did the rest of our glassworks for the year (I still have a scar)... still really wild seeing glass on a lathe !!

[@jackarmstrong4051]

wow beautiful work dude

[@ktfords]

Thanks a lot!

[@joyztik]

Would it be possible to weld a piece of glass tube to the side of a mason jar to convert it into a filtering flask? Like a DIY project.

[@timecode37]

sure, but be aware that you won't be able to do any vacuum filtration with a mason jar

[@LittleGreenB4g]

Great informative video. Thanks for sharing!

[@ktfords]

Thanks!

[@jwdshiff]

what model torch is the small needle flame one you were using for most of the video? it looks like a great little lathe torch (not the nationals - although very cool quartz tips)

[@ktfords]

jwdshiff Glad you like the torches. If you are interested, I just posted how to make the quartz tips. thanks

Your ground joints will stop popping off if you use graphite tape!

[@AmbassadorJJ]

How do you finish these up? Do you anneal these in an oven or is there a special way to do it?

[@ktfords]

Good question, once I take it out of the late, I put it into the annealing oven for 30 minutes at 565 Celsius. This process will relieve all this stress that I created while I worked on it.

[@BaKer312213]

Found my dream job

[@jaskaransingh1761]

any scientific glass blowing school in usa or Canada??

[@ktfords]

+Jaskaran Singh Not that I know of..try to find glass company and learn from the bottom up.

[@Василий-с5х]

Я вручную это делаю.

[@ktfords]

FYI, Manually is not the only way, just a way. The reason for the video, was to show how to the job with no card board supports and come out with a completely straight center tube. Can you do that Manually???? No you can't.
