O novo VANTAstar^TM é o mais novo membro de nossa família. Este leitor de microplacas multimodo compacto foi concebido para ser operado de forma fácil e flexível assegurando que a programação do equipamento seja feita sem esforço para geração de dados de forma simplificada. Equipado com nosso sistema patenteado de monocromadores duplos LVF, filtros, espectrômetro UV/VIS e tecnologia de faixa dinâmica estendida EDR, o VANTAstarTM pode atender uma ampla gama de aplicações em pesquisa básica e ciências da vida.

O VANTAstar é um leitor de microplacas multimodo configurável compatível com todos os modelos de placas até 384 poços. A tecnologia de faixa dinâmica estendida (EDR) combinada com o sistema de autofoco aliados a redução de interferências cruzadas em luminescência faz com que os ensaios sejam realizados de maneira simples e sem otimizações manuais supérfluas.

Com a Unidade de Controle Atmosférico, incubação, múltiplas opções de agitação, escaneamento de poços e injetores de reagentes com aquecedor e misturador, o VANTAstar atende à todos os ensaios com base em células vivas.
