      Broken sep funnel. can it be fixed?  Bookmark   

i was trying to turn the knob to drain my junk and it snapped right where the end of the bulb meets the turner/spindle thing. i have all the glass so like if i had something to get it back together it would be solid again, but i don't know of anything that can hold glass acceps cyanoacrylate which is acetone soluble...that wouldent do me much good...any suggestions?

Lugh said it.
Very good form to have made a working arrangement with a scientific glass blower. Even better form to be able to make small repairs on borosilicate oneself.

      find a glassblower...  Bookmark   

In my experience, a glass blower will charge about twenty bucks or so to do the necessary repair. Part of the charge will be for "ashing" the broken parts prior to welding them. They put it in a kiln and ramp the temperature way up then back down to minimize the possibility of exposing the glassblower to toxins. Brand new glass doesn't need ashing and probably costs ten dollars to repair. At least in my neck of the woods.

      actually that's not why..  Bookmark   

they clean in an ultrasonic bath.. they cycle the ware cause the heat of welding the joint causes temper stress and strain, so the annealing of the repair joint must be done...

  That usually happens after the repair..

yah and that'll cost $20-40 or so.. they'll have to put a new stopcock in but not a problem..

      ashing vs annealing  Bookmark   

Well, CL... my local scientific glassblower puts used glassware in the oven overnight to volatize anything nasty before doing repairs and they refer to this process as "ashing". Annealing happens afterward to relieve stress. Ashing, welding a fitting on and annealing costs twenty bucks. Drop it off monday, pick it up wednesday.

      yes he will...  Bookmark   

Your glassblower is able to remove a stuck stopcock and probably won't charge you for it if he's welding your funnel back together. Be sure to ask if they have any glassware laying around that you might be able to use, mine had a box full of useful (for me)RBF's they were willing to sell for next to nothing because they'd been in the way for a few years. Every bee should try to meet a scientific glass blower if possible. And since we all probably like to tour a shop full of cool tools, it's a fun afternoon.

Remember to clean it thoroughly before taking it in to get repaired.

      Hey jimwig, lots of places can fix your ultrasonic  Bookmark   

Google for someplace that fixes lab equipment and analytical balances... I bet they can make your bath shake! Or just contact the manufacturer, they'll do it or recommend someone.

I used 5 minute epoxy on my filter funnel, still holding after many uses. I'd try it on the sep funnel.

A filter funnel does not undergo the same torture a sep funnel could be put thru,,,,,,
If you need it in 5 minutes, use the epoxy. If it's not needed right away, see the glassblower.
