CueSee® Mix is a unique packaging concept that is revolutionizing quality control. This innovative, dual-chambered device keeps various fractions separated and prevents reactions between components of the desired matrix. A simple twisting motion allows the fractions to combine. Then, mix the components and the matrix is ready to test. CueSee® Mix will open doors with its ease of use, elimination of the need for pipetting, and by solving matrix interactions - all in a single container. This concept is ideal for creating liquid matrices that are as close to human specimens as possible and suitable for quality control, calibration verification, proficiency testing, competency assessment, method validations, and lot comparisons.
