Bruker's Acquifer Imaging Machine (IM) is a fully automated widefield microscope that can perform brightfield and fluorescence imaging on various materials. This technology is ideal for high-content and phenotypic screening of small-model organisms due to its complete data storage and processing capabilities.
The combination of a static sample container and mobile optical unit provides stability during imaging, making it excellent for imaging motion-sensitive samples like non-adherent cell cultures or embryos.
The IM system has unique features, including temperature regulation, a robotic lid, and an open interface. The seamless integration with automated workflows enables researchers to conduct sophisticated time-lapse studies, screening, and high-throughput imaging tests.
Only Acquifer IM Provides:
Intuitive Design and Use
- Adaptive feedback microscopy
- Software and workflow for imaging automatically centered samples and visualizing enormous screening datasets
- Effortless configuration of imaging experiments
Sample-Centered Approach
- Built-in temperature control (20 to 40 °C) with ± 0.5 °C homogeneity over whole plate and over time
- Optimal imaging conditions for sensitive specimens and long-term observations
- Uniblock optical design moves to your sample while your sample remains stationary

To achieve precise live-sample imaging, the sample chamber temperature is tightly regulated. The temperature control mechanisms are engineered for long-term stability and to minimize gradients across the plate.
Versatile Application

The versatile and user-friendly machine control and assay configuration accommodates a wide range of specimens, from whole organisms and microorganisms to cell monolayers, stem cells, organoids, spheroids, and tissues.
Supervised Feedback Microscopy
The Plate-Viewer software allows for the easy visualization of low-magnification pre-screen data of a full microtiter plate. Various tools and matching algorithms facilitate the selection of regions of interest for each well and ensure robust localization of target structures.
Add-On Photo Manipulation
