That would be Sigma-Aldrich http://www.sigmaaldrich.com/sigma-aldrich/home.html
They are a chemical manufacturer and supplier, particulary into universities. The way I read it, most boffins would one of their catalogues delivered each qtr and dream up ways to spend their grant money on its goodies.
Here is an example of a Dyesol product in their catalogue. http://www.sigmaaldrich.com/catalog/ProductDetail.do?N4=703214|ALDRICH&N5=SEARCH_CONCAT_PNO|BRAND_KEY&F=SPEC
More expensive than direct from Dyesol. $1000US a gram, where we charge $1000AUD
