Hi Christian,

I am no expert in animal studies but based on my experience in our department, products from Phoenix research lab seems to be up to the standard. Here is the link to the products that they have :http://www.phoenixreslabs.com/products/

You should check out the rodent Ocuscience system.  

This link will give you information about the system with many citations using it: http://www.ocuscience.us/id91.html

Thank you so much Nabin and Carl for your help!
