I've uploaded some images, anyone have any ideas on what they are used for? I figure the square thing is most likely for some demonstration about circulation and has no practical use.

Top looks like a goofy long ass burette (what kind of end is on the other end). The bottom one seems like it could be some sort of radiation exposure tube almost. As if the tube is placed around something like a radioactive sample, or even light or heat (some form of energy).

I was woundering the same thing about the bottom one and if it maybe some kind of flask for doing photochemistry. It would give alot more surface area exposed to light for the reaction to progress. If not, thats sure as hell what I would use it for

Interesting suggestion! I bet it was used for the classical DCPIP/chloroplast reduction demonstrations done in biology.

The long thing I think is just a thistle tube. A pointlessly large thistle tube.

That was the word I was looking for. I couldn't think of it, and I didn't want to say "stupid ass funnel". Thistle tubes are useless IMO if you have an addition or separatory funnel and glass tubing.

I think this thing is a water distillation set up of some sort, but I can't figure out how the damn thing would work, so does anyone have an idea?
It is clearly missing something since it plugs in, but I don't see how to attach any other items to it that would be heated by it, etc. Also it seems like no matter where you put in the liquid, it ends up going through the entire thing, but I haven't really studied it at all much.

Maybe I can get some useful thing out of it at least?

This is off the topic of the thread, but I figured it went best here vs making a new thread.
I have this broken heating magnetic stirrer. Right now it is in pieces, but I can skrew it back together. but it hasn't had any magnetic properties, let alone stirring capabilities and the heat didn't appear to be controllable - it was either on when it was plugged in, or off when it wasn't. I don't understand electronics all that well, but would you think it is worth trying to fix, or just toss it?

Douchermann · « **Reply #7 on:** June 08, 2009, 05:08:31 AM »

You could send it to me and I could take a look at it. It should be a solid state electromagnet that rotates it's field, as opposed to a motor that spins a magnet. This is because of the heating function. Because of this, it might be very difficult to diagnose the issue, but I could sure as hell try. It's moderately difficult to run a crash course in electronic engineering through the keyboard to you haha.

Vesp · « **Reply #8 on:** June 08, 2009, 06:04:24 AM »

I seriously might.
You'd send it back if you got it working, right?

Edit: When I've looked at it, I think it really just needs to be reconnected at the bottom, and make get a new controller thing. It looked like there was some heat damage done to it.

Douchermann · « **Reply #9 on:** June 08, 2009, 07:25:56 AM »

Well it depends on what kind of controller thing we're talking about. This isn't the pre-1999 anymore haha. They don't sell replacement parts for anything lol. If you sent it here, I could take a look at it, tell you what was wrong with it, attempt to fix it, and if I can't, I could send it back, or throw it out for you haha.

Sedit · « **Reply #10 on:** June 08, 2009, 08:10:29 AM »

Can you open it up and show us a picture Vesp. Im the man when it comes to electronics but I would have to have an idea whats inside.

It sounds like you should have 8 electro magnets inside to spin the bar. These may act as a current limiter also but if they(or even one) is burnt out and the heating element runs parallel to it then all the power will be going streight to it instead of some being diverted to the magnets. Its just a hunch because I have no idea what it consist of.

Vesp · « **Reply #11 on:** June 08, 2009, 08:20:48 AM »

I'll try to get a decent picture of it soon, so you can help diagnose it. I'll probably send it to Douchermann, since that seems like the best way to fix it. I doubt I could do it.

Vesp · « **Reply #12 on:** June 10, 2009, 06:16:41 AM »

Here are some pictures of the inside of the magnetic stirrer. Hope this helps, but I doubt it will. It was the best I could get (took them at night in a porch light)

If you think it will help, I'll get better pictures tomorrow.

heh, so whats the problem doc?

Sedit · « **Reply #13 on:** June 12, 2009, 05:41:55 AM »

Fuck I posted a whole long thing here but it didnt go thru....

err summery time...

that thing on the right be it a capacitor or control knob looks shorted across the terminals....

Main problem you have with the heat is what I believe is your thermocouple there(white thing connected to the board with little wires...looks like a white bullet) looks burnt where it connects....no thermocouple no heat control, just steady on.

Post some pictures of the face of the board so I can see, and go over each piece with a multimeter to make sure you have continuity...

Smell for oil from blown capacitors and look for smoke around the resistors.

all right I'll get more pictures tomorrow.

I didn't even think of that! Good idea.

So what ever happened with this Vesp did you find out what was blown out?

Im going to post some pictures sometime in the next few days or so showing a DYI magnetic stirring/oil bath. Its all self contained and uses the heating elements out of an old hair dryer. I already had the oil bath up to 350 degrees F and I have no doubt that it could reach 450-500 with ease. Now its just a matter of fixating it to my homemade magnetic stirring unit.

Keep us updated on how the hotplate is comming along. If ya can fix it send it to me before you throw it out

Ill put it to good use.

Vesp · « **Reply #16 on:** June 25, 2009, 05:33:22 AM »

I haven't looked at it since. I think I might try to take it to some eletronic repair dude and see if they can charge me a fuck ton to fix it.. I really need one and I don't know enough about electronics to figure out the problem - plus I don't have a soldering kit.

Sedit · « **Reply #17 on:** June 26, 2009, 12:48:49 AM »

Honestly my pencil soldering guns I found so unacceptable for soldering small fragile pieces that I chose to use a nail on the end of a stick that has been warmed with an alcohol lamp. Resisters and transistors have a habit of blowing out when working with pencial irons.. and I wont even get started on the pain it is to solder a microchip.

Like I said before try to get some detailed pictured of the under side and the top side of the motherboard itself so I can see what is attached to where and Im 99% sure I could walk you thru the rest. Why spend 50-100$ to fix something when radio shack will cost about 2$-5$.

Send me a piece of unused glassware and the hotplate and I will fix it and send you back the hotplate in a jiffy(you pay shipping;D).... Hey a poor mans gotta do what a poor mans gotta do

What sort of glassware?

That doesn't sound like a bad deal at all to me...

Sedit · « **Reply #19 on:** June 26, 2009, 02:42:41 AM »

HEHE

Whatcha got

Theres almost no doubt I could fix it because I doubt that more the 1 thing failed and thats tossing everying else out of wack.

Ill give any glassware back if I feel its totaly fucked...{ect.....blown coil on an electromagent cant be fixed at radio shack...most of the time.} That takes specific replacement parts.
