Our Patented Fixed Focus Technology

The Countstar Rigel is equipped with a highly precise, full-metal optical bench, based on our patented “Fixed Focus Technology” (pFFT), never demanding a user-dependent focusing prior to any image acquisition.

Our Innovative Image Recognition Algorithms

Our protected image recognition algorithms analyze more than 20 single parameters of each classified object.

Intuitive, Three-step Analysis

The Countstar Rigel is designed to guide you from sample to results in less time than comparable methods. It simplifies your work flow, allow-ing for increased productivity, and increases efficiency by analysis more parameters than classical methods.

Step One: Staining and injecting the sample
Step Two: Selecting appropriate BioApp and start analysis
Step Three: Viewing Images and checking result data

Compact, All-in-one Design

Ultra-sensitive 10.4’’ touchscreen

App-structured user interface allows for an intuitive, 21CFR Part 11 compliant, user experience. Personalized user profiles guarantee for a fast access to specific menu features.

Individually Designed and Customizable BioApps

Individually designed and customizable BioApps (assay protocol tem-plates) offer the access to an in-depth analysis of cells.

Up to Three Fields of View per Sample with High Repeatability

Up to three fields of interest selectable views per chamber to increase accuracy and precision of low concentrated sample analysis

Up to Four LED Wavelengths for up to 13 Fluorescence Channel Combinations

Available with up to 4 LED excitation wavelengths and 5 detection filters, allowing for 13 different combinations of fluorescent analysis.

Filter combinations of the Countstar Rigel series for popular fluorophores

Acquisition of bright-field and up to 4 fluorescent images automatically

in a single test sequence

Accuracy and Precision

The Countstar Rigel hard- and software creates trust by its ability to analyze five samples at a time producing accurate and precise results. The patented Fixed Focus Technology in combination with the exact chamber height of 190µm in each Countstar chamber are the basis for a coefficient of variation (cv) of less than 5% regarding cell concentration and viability in the range of 2×10⁵ to 1×10⁷  cells/mL.

Reproducibility tests chamber to chamber= cv <5 %
Reproducibility test slide to slide; cv <5 %
Reproducibility test Countstar Rigel to Countstar Rigel: cv < 5%

Accuracy and Reproducibility Test between 6 Countstar Rigel analyzers

Meeting the Actual Requirements of Modern cGMP Biopharmaceutical Research and Manufacturing

The Countstar Rigel is designed to meet all actual requirements in modern cGMP regulated biopharmaceutical research and production environments. The software can be operated compliantly to FDA’s 21 CFR Part 11 regulations. Key features include tamper-resistant software, encrypted storage results and image data, multi-role user access management, electronic signatures and log files, that provide for a secure audit trail. Customizable IQ/OQ document editorial service and PQ support by ALIT experts are offered to guarantee a seamless integration of Countstar Rigel analyzers in the validated productions and laboratories.
