With no need for additional equipment, pressure or vacuum, solvent absorption is the most economic and user friendly concentration technique available to the clinician and research scientist. Just fill the unit with the solution to be concentrated, wait for the desired concentration level to be achieved and then pipette the concentration sample from the bottom of the reservoir. Ideal for general purpose laboratory concentration or purification prior to further analysis, Vivapore is particularly suited for labile solutions that can denature with alternative shear or pressure inducing methods or require processing in a cold room environment. Vivapore concentrators extend the solvent absorption technique to a totally new level of performance, application potential and ease of use. Requires stand.
