Discovery Products and Services Inc. (DPS) is a new but aggressively growing company, which has assembled a wide array of building blocks and reagents to support and enhance your chemistry needs. Our resource pool includes chemicals from United States, Eastern Europe, China, South Korea, India and Central Asia. We ONLY offer samples we can readily deliver. In a nutshell, if it is not on the shelf, we do not offer it. Updates to our availability are weekly and while some samples we have limited supply of, we aggressively pursue a restocking policy to bring our on hand amounts back to projected levels.
