Funding

Actually, I work 2 jobs. The full-time job takes care of my needs.
The part-time job takes care of my wants and hobbies. It's taken me
a few years to assemble my lab but IMHO, condensers are
probably the most creative labglass I've ever laid eyes on. This is why
I collect them. Current types in my collection are Alihn, Buchler,
Cold Finger, Friedrich, Graham, Liebig. The retorts I look for are antique.
I haven't had much success there.

glass retorts

There are 2 glass retorts up for sale on Ebay now under item 3832981725. Most likely you have already noticed.

Glassware has always fascinated me too -some of it gives me a woody.

Lot

Currently, I'm bidding on a small "lot" of labglass that contains 2
condensers I'm looking for. If the eBay snipers don't blow my
brains out, I'll post back with the excess for the forum members.
Wish me luck !

P.S. Magpie, can't argue with you on your last post - Mr. Johnson stands
pony up $400 for my last centrifuge only to get the rotor. All I wanted was the fucking rotor ! But, no problem - 1 centrifuge will back up the other ! I'll never be lonely !

I do have a 300mm graham condender, with 24/40 joints, in good condition, the only exception is a slight stain of potassium permanganate on the joints, I don't know how to remove. Interest? I guess I'll decide on my books, I have 16 chem textbooks, I don't need all of them,but I'll keep a few. Now I just need to keep enough glassware to carry out basic reaction, and extracting plant alkaloids.

I used one to get my hotplate so I don't see why you can't. You sign up with a site and enter your ebay ID, the max price you want to pay and the item #. It will enter a dollar over the next highest bidder about 5 seconds before the bidding ends. However there are other snipers so your max price determines whether you win or lose sometimes. What if, what is isn\'t true?

I think they just delete your account if you are caught. Edit: I found this on eBay "eBay rules prohibit use of this Contact eBay Member feature to offer to buy or sell directly without bidding on and winning the item on eBay. We strongly advise recipients of these email offers to report them to eBay. Participants in these 'off eBay' transactions lose their ability to use eBay Feedback and our buyer protection programs.

Requirements: - Watch or stopwatch with countdown function. - two open browser tabs - price limit. Open the main page for the auction about 15 minutes before it ends. Take the stopwatch and set it to countdown from 1 minute. Click bid but make sure it opens in a different window. Make sure you're logged in, enter your max price so that you only have to make one click to submit. Keep refreshing the main page for the auction as fast as possible after the 2 minute mark. Start your timer at 1 minute and submit your bid preferably at 10s, somewhat earlier if you have a slower connection. Works everytime for me.

MUHAHAHAHAHAHAHA ! thunderfvck National Hazard Posts: 347 Registered: 30-1-2004 Location: noitacoL Member Is Offline Mood: No Mood Sorry, I just have a couple of things to say about sniping tools...I love them! I use SnipeRight which I think is one of the best ones out there right now. I registered the product for about$15 American, not too shabby I think.

What I like about this program is that they have their own server that deals with the sniping. So I don't even have to be on the computer when the bid ends. This is especially useful since I'm often in school when the bids do end, and unless I want to run out of class to snipe an auction on these SHIT computers...I think you get the point.

You can also choose the times that you want to snipe at, usually about 8 seconds does the trick although you can go as low as 2 seconds but that's pushing it. The server is very fast and I don't have to worry about my computer locking up on me which has been a problem for me many a time. You simply choose your max bid, and the time you want it sniped at and it's done! Go to bed, play with yourself, whatever! They'll do it all themselves.

I've never lost a bid because of this.

You can even simulate "real" bidding patterns so that it doesn't look like you've sniped it.

All in all, I think the program pays for itself (a comment someone else had said which I completely agree with).

If you're going to snipe - SnipeRight!

hahaha. I'm not affiliated with them in any way, but it really is a great program!

MadHatter, I've received the centrifuge! The customs seem to not even have opened the crate, there was only one layer of duct tape on the box.

It's very beatiful and has a place of honor on one of my tables. I haven't tested it yet, I need to go and buy a 220-->110 volt transformer capable of at least 150W first; which I cannot really spare the cash for until the 27th. Then I'll finally be able to make ultra-pure PbO<SUB>2</SUB>!

I don't know how I will ever repay your kindness. If I ever find a way of making good PbO<SUB>2</SUB> anodes, I'll send you the first 3 I make.

Thank you!

Condensers

I just purchased 2 more condensers for my collection on eBay. I wish they had been in
lots so I could ship the rest out. One is a double-jacketed Liebig and the other is a reflux
condenser that looks like an inverted Graham. The water flows through the coil instead of
the gasses needing to be condensed. I'll post pictures when I receive them. I've been
working a hell of a lot of overtime lately, so it was time to shop ! May as well enjoy it !

 Quote: The water flows through the coil instead of the gasses

This is referred to as a Dimroth condensor in europe.

It has the advantage that it can be used in angled horizontal position, contrary to a graham. Cooling effectiveness is lower as gasses can creep up along the wall, which is at room temperature.

Condenser

Vulture, thank you for the info on this ! I'll post the pictures of both condensers when they
come in.

I actually saw one of those Dimroth condensers in the shop next to mine, but the new guy turned
it back over to the State Of Maryland, required by law, instead of giving it to me. I would have
loved receiving this, at no charge, to my collection. What a waste ! What is the State Of
Maryland going to use it for ? It was in a machine shop !

the double-walled(high efficiency) Liebig on the bottom.

I'm waiting for another condenser to come in. It's part of a vacuum distillation setup. It looks
like a high efficiency Allihn condenser. I'll post pictures when it arrives.
