MP Biomedicals is a biotech company that specializes in Cell Biology and Molecular Biology products.  I am most familiar with MP Biomedicals as the main supplier of radioactivity to most scientists that I know.  Below is a link to their Promotions page, where they offer free samples.  I am most intrigued by the Encapsulated LB Media that they are currently offering.  They might save a lot of time for people who grow a lot of bacteria.
