Round Bottom Flask: April 2010
http://roundbottomflask.blogspot.com/2010_04_01_archive.html
Apr 30, 2010. RBF Teaches: Drying solvents. So, when you do real chemistry and are able to use a manifold appropriately you can start to look at some genuinely difficult chemistry requiring dry conditions. The dry (or anhydrous) reaction is quite commonplace in synthetic labs and you will most likely come across it in your career, probably very early on. Once again, I suggest reading APOC. The use of activated molecular sieves or some other innocuous dried material (e.g. KOH for TEA) can be place...Begin...
Round Bottom Flask: November 2009
http://roundbottomflask.blogspot.com/2009_11_01_archive.html
Nov 30, 2009. RBF Teaches: Column chromatography. Listen up kiddies,. Column chromatography is much the same as TLC. Except this time the solvent front is forced down instead of being drawn up. All of the principles. IMPORTANT NOTE: Silica dust is toxic to inhalation (similar to asbestos) and all measuring of silica should be done in a fume hood and FOR GOD'S SAKES DON'T BREATHE IT IN! Step 1: Choosing the column. This leads us to the important bit: the actual column. So APOC. MSG edit: everyone has thei...
Round Bottom Flask: February 2010
http://roundbottomflask.blogspot.com/2010_02_01_archive.html
Feb 26, 2010. MPLC vs Flash Chromatography. Yesterday an old argument reemerged in the lab. On discussing the use of an auto-column and the ways in which we can implement it in the lab and the ways in which time will be saved one of us mentioned that an auto-column MPLC would never be as good as a good ol' hand worked flash column. Image 1) and the Teledyne Combi Flash. Image 2) as well as the Kyle Finchsigmate's MPLC for the people. Image 3). But, are they as good as the good ol' hand column. Reusable c...
Round Bottom Flask: Damn bureaucrats! Damn lab monkeys!
http://roundbottomflask.blogspot.com/2010/04/damn-bureaucrats-damn-lab-monkeys.html
Apr 29, 2010. On a chemical side not unrelated, our CEM microwave has failed with a power supply error and the damn thing just came back with a replacement power supply. WTF! I have tried to run some reactions on the damn thing and it fails after 5min. Our water pumps that have lasted for years have all decided to trip all the fumehoods and die all at the same time. We have a brand new MPLC that we can't use and I really want to play with it :P. All in all what a crazy start to this semester. Maybe someo...
Round Bottom Flask: December 2009
http://roundbottomflask.blogspot.com/2009_12_01_archive.html
Dec 26, 2009. Season greetings from RBF. Hope you guys had a great christmas. Personally I had one of the better ones this year, and a contributing factor was some pretty neat gifts (which are chemistry related). First up, my gorgeous girlfriend gave me a copy of Julia Child's 'Mastering the art of French cooking'. So there's the link. My second chemistry related christmas gift is this truly stylish. Shirt from the folks at webelements.com. Dec 18, 2009. Came across this on Google Reader this morning:.

Laquo; The Good, The Bad, and The Ugly. Art On A Chip. Something Deeply Wrong With Chemistry. An example of what is currently wrong with chemistry culture, even though it is dated. Future chemistry faculty will have to be twice as smart, work with twice the efficiency, and reach the correct positions of influence if they want this type of unhealthy cultural attitudes to finally be put to rest. This is my goal at least. Update 1: Guido Koch now. Update 4: A transcribed letter from Robert Tjian. I realize ...

Carbon Tet: Carbon Tetrachloride
http://carbontet.blogspot.com/2010/08/carbon-tetrachloride.html
Musings of an organic chemist. Sunday, August 1, 2010. But this is a chemistry blog, so let's talk a bit more about the molecule. Carbon tet was first prepared way back in 1839. The French chemist Henri Victor Regnault reacted chloroform with chlorine producing carbon tet and HCl. Now it is made from methane but before the 1950s it was prepared by chlorination of carbon disulfide. It could be your hedge against inflation. Welcome back. What have you been up to? Really miss reading your blog.
Carbon Tet: October 2008
http://carbontet.blogspot.com/2008_10_01_archive.html
Musings of an organic chemist. Thursday, October 9, 2008. A new NIH policy was announced yesterday. And will be applicable to all proposals submitted on or after January 25, 2009. The policy cuts down on the number of times one can resubmit a grant proposal. Currently if a proposal is not funded an amended application can be resubmitted two more times. This policy will restrict all new application and all competing renewal applications to only a single resubmission. Wednesday, October 8, 2008.

Now with hood space! Arse, ‘innit? So, as a scientist, here’s my obligatory post regarding the whole “Arsenic Replacing Phosphorus in DNA Backbone” thing. Whether or not it’s true, it really seems as though Wolfe-Simon. Their case, and that’s a problem. (If you want a full breakdown of why the paper is kind of flawed, check out commentaries by Derek Lowe.

Now with hood space! Chemjobber does it again! Really, he couldn’t be better at what he does – even if he’s not even specifically trying. Way back when he cross posted. Info about my search for grad schools, I got much more than I bargained for.* An editor of C&EN came across my blog, enjoyed the ‘Chiral Jones Experience,’ and contacted me with interest in picking me up over at CENtral Science. So here are the deets:. Yes, I’ll be blogging for C&EN! Incriminating happy hour pics. I’ll let him intro...

Sorry it’s a bit small, I suggest you view the full pic. Check out the first and last entries I’ve included from my screen-capture. Have a chuckle at it before ACD gets wise and fixes it. Either someone at ACD labs has a weird sense of humor, is a dissenter, or there’s some skulduggery afoot from a third party. You are ...

Here is a quick and dirty fix for the end of your column. Simply find an appropriately sized disposable nalgene syringe (polypropylene types only, otherwise you will extract out nasty plasticisers, don't use the Terumo ones with the black plunger tips), cut the end off and CAREFULLY (with thick gloves).
