TKA 310 Line of Fully Automated Analyzers for EIA/ELISA Assays

TKA 310 Line of Fully Automated Analyzers for EIA/ELISA Assays Laboratories that perform few analyses can afford to equip themselves with one of these “walk-away” analyzers, thus avoiding the use of several machines, helping reduce costs, save room and protect against human error. The programs allow the creation of profiles containing up to 8 assays to be carried out in a single session. It is also possible to carry out different assays on the same microplate, provided that such assays have the same temperature and incubation schedule. The two models in this line—the TKA 312 and TKA 313—, perform similarly, they only differ in the number of operated microplates: two and three respectively. Like all TKA Analyzers the software of these units allow the storage of Standard Curves that can be retrieved later and used to adjust one or two Calibrators, reducing analysis cost. Reagent containers are included in the kit.
