Hampton makes a "Detergent Screen" that works the same way as the Additive Screen.
http://hamptonresearch.com/product_detail.aspx?cid=1&sid=39&pid=31 It has 96 unique detergent reagents for crystal screening. It is a bit expensive, but if you don't want to purchase the whole kit you could just download the formulation table and then you will have a nice long list of possibilities.

So, besides chaps, is there any other detergents to be used during crystal screening? All suggestions are welcome. Thanks&Regards, Yuan -- Michael C.
