The high-efficiency monochromator and filter-based optical system, combined with an ultra-cooled photomultiplier tube (PMT), minimizes noise while increasing sensitivity, selectivity, and dynamic range.
Advanced shaking and user-installable gas mixer (CO2/O2) that support ideal environments for cell-based and microbial growth experiments are available as optional upgrades.
Automatically identify filter sets using NFC functionality, simplifying workflows and ensuring accuracy and reliability.
Precise and intuitive temperature regulation—from 5°C above ambient conditions up to 66 °C—empowering your lab to perform a wide range of temperature-sensitive assays with confidence.
Z-height optimization automatically adjusts the detection height to maximize sensitivity and signal quality—while minimizing sample volume—ensuring reliable results even in low-volume or precious samples.
The SpectraDrop Micro-Volume Microplate for low-volume (2 to 4 μL) and SpectraCuvette™ Adapter Plate for cuvette-based applications eliminate the need for additional instrumentation.
The intuitive touchscreen software simplifies tasks with Quick Read icons that save time when starting new experiments and a personalized library that stores frequently used protocols.
The optional enhanced time-resolved fluorescence (TRF) detection module is optimal for quantitating as little as femtogram protein samples, providing improved sensitivity, extended signal stability and versatility to support a wide range of applications.
