ferhat00 Posted January 6, 2010 Share Posted January 6, 2010 Are there any suppliers which sell fluorescent dyes, such as fluorescein, rhodamine, oregon green etc in large bulk volume, such as 1-2Litre bottles? Many thanks in advance. Link to comment Share on other sites More sharing options...
CharonY Posted January 7, 2010 Share Posted January 7, 2010 Uh. Litres? No idea. But as they are more stable in dried form I would search for that instead. Sigma for instance sells 500 g of rhodamine for around 130 bucks, fluorescein was around 200, I think. Link to comment Share on other sites More sharing options...
Mokele Posted January 9, 2010 Share Posted January 9, 2010 Look into supply companies for ecology and watershed management. Non-toxic colored dyes are often used to evaluate stream flow rates and watersheds. Link to comment Share on other sites More sharing options...
