INTEGRA reagent reservoirs offer a convenient solution for the temporary storage of non-solvent based liquids during any pipetting application. The system consists of disposable, crystal clear polystyrene inserts that fit into reusable bases with clearly visible volume markings. The pour-back spouts in the corners of the reservoir allow pouring back the liquid into the original container without spills. The reagent reservoirs are available in 10, 25, 100 ml size and are stackable for space saving storage. Features and benefits: - Light is refracted so that graduations below the liquid surface become invisible, making it easier to identify the exact desired volume line. - Pour-back spouts molded into the corners of each reagent reservoir control liquid flow and enable the easy, spill-free return of reagent to its original container. - Base accommodates two reservoirs, one acting as a lid.
