Beckman Coulter, known for superior quality products, excels in terms of being reliable and durable. It brings PROTEOMELAB™ XL-A/XL-I, one of the latest additions in the field of Laboratory ultracentrifuge. It comes with in-solution characterization of small structures, colloids, particles, aggregates, oligomers, and proteins delivering perfect results that one can depend on. In-solution characterization facilitates testing in native conditions, allowing individuals to govern sample testing environment that accurately suits their needs. ProteomeLab XL-A/XL-I incorporates use of special column-free separating technique to estimate the relative change in distribution of molecular weights, along with offering an efficient and smooth mean for measuring self-associating systems, stoichiometry, and heterogeneity. Since the measurements are established on first principles of hydrodynamics and thermodynamics, it eliminates the need for standards or calibrations; as a result of which, individuals can spend more time on discovery and less time on setup.
