Introducing the alto™ microplate reader

Cerillo's next-generation microplate reader accommodates endpoint and kinetic optical density measurements with unparalleled flexibility. Ideal for ELISA and high-throughput microbial growth curve applications.

this powerful optical system provides flexible calibration modes, accommodating a wide array of experiments including ELISA and microbial growth curves with diverse starting points.

Alto seamlessly transitions between endpoint measurements, offering snapshots of reaction states and kinetic growth curve measurements, facilitating dynamic experiment tracking over time. With flexible calibration modes, alto is an ideal plate reader for a wide range of experimental conditions and enables high throughput experimentation.

Whether you work for an academic institution, a fast-paced biotechnology organization, or a large pharmaceutical company, the alto research platform can help you make your first or your next breakthrough discovery.
