Storage plates are ideal for automated storing, archiving, and transporting chemicals. Rigid, automation-compatible plates are designed for various protocols requiring solvent resistance, including DSMO. Two full-width white writing patches provide easy labeling or bar coding. Polypropylene lid is compatible with automated lidding and de-lidding devices. Ethylene vinyl acetate (EVA) mat cover for U-bottom plates significantly reduces cross-contamination for long-term storage. Mat cover working volume is 160??L with DSMO and 200??L with aqueous solutions.
