Two new Tabless Tube Holder accessories for the Strata® and Strata™-X lines of silica-based and polymeric solid phase extraction (SPE) sorbents are available. These accessories hold SPE tubes in 96-well spacing to integrate with automated systems. All Strata and Strata-X products are now available in the tabless 1 mL tube format, enabling the user to arrange multiple sorbents within the holders. Users can also remove and replace a single SPE tube should they make an error.
