Trip Dr Posted December 9, 2003 Hello all, after doing a number of extractions that im less than happy with i've decided to try and get my hands on some top quality solvents. Now i've been checking out batco.com.au and come up with a few q's The solvents come in grades like extra pure, reagent grade, technical grade and with other names like 'dried analaR' as well as chromatography and spectroscoopy types. Now we would want the most pure grade but which is it? Or which grade is suited for basic extractions etc. ? Cheers Trip Dr Share this post Link to post Share on other sites
friendly Posted December 10, 2003 Usually reagent grade is good enough. However, read the label for impurities and other additives before you buy. A good way to test the purity of solvents on hand is to evaporate a little off in a glass petri dish and see if any residue remains. If no residue remains, the solvent is clean.

Shamanorrhea Posted December 14, 2003 Trip Dr, that link doesn't work. I was looking on google as well and it can't seem to find any mention of batco at all. Did you type something wrong? Share this post Link to post Share on other sites
