Texan reagent reservoirs are reusable -- an environmentally sound alternative to disposable reagent reservoirs. Their extra-large capacity means fewer refills and time saved. The V-shaped basin is compatible with both eight- and twelve-place multiple pipettors with minimal reagent waste. Lids are removable -- attached with ball and socket hinges -- and latch tightly for secure storage of left-over reagents. With lids closed, Texan reagent reservoirs are stackable. A perimeter ridge on the lid prevents sliding. Construction is clear, chemical-resistant, autoclavable polypropylene. Molded graduation marks provide volume indication at 25, 50, 75, 100, 125, and 150 mL.
