Echo Qualified 384-Well Low Dead Volume (LDV) Source Microplates are designed to minimize dead volume when using the Echo Liquid Handler. This microplate is constructed of Cyclic Olefin Copolymer (COC) for optimal acoustic transfer performance and has been specially optimized for high precision aqueous liquid transfers when using the Echo 525 Liquid Handler. Each lot of our coated source microplates is tested and certified to meet stringent transfer performance specifications on the Echo acoustic liquid handling platform. The 384LDV Echo Qualified Carboxyl Coated Source Microplate is distinguishable from the standard Echo Qualified 384-well Source Microplates by a yellow dot on the long side of the lower P-24 corner.
