MassSTAR – fast, reliable and fully automated for clinical labs
MassSTAR automates the processing of Chromsystems’ diagnostic assays, offering a CE-IVD-compliant, walkaway solution for clinical laboratories. Designed to replicate manual workflows with high fidelity, it minimises pipetting errors while maintaining analytical precision.
With built-in error handling, workflow monitoring and Total Aspiration and Dispense Monitoring (TADM™), MassSTAR tracks every pipetting step in real time, detecting issues such as blood clots, foam or incorrect volumes and initiating corrective actions automatically. The intuitive graphical user interface (GUI) guides users through setup, monitors progress and supports a wide range of sample tube formats. MassSTAR also performs inventory checks for samples, reagents and labware and exports sample lists with target values directly to LC-MS/MS instruments, enabling laboratories to process high sample volumes efficiently with minimal manual intervention.

Total aspiration and dispense monitoring

One of the key safety features is the total aspiration and dispense monitoring (TADM™) of the instrument. Each aspiration and dispensing step, also in each pipetting channel, is monitored in real-time. TADM verifies the sample transfer with a traceable digital audit trail and identifies errors such as blood clots or incorrect volumes that have been transferred. In case an error during aspiration is detected a new attempt to pipette the sample is started. If the error is repeated, the sample is then excluded. Another advantage of TADM is its ability to detect the use of incorrect reagents.
System components
The barcode reader
The integrated 1D barcode reader ensures seamless identification and tracking of all labware:
1D barcode reader
Supports sample tubes, microplates, and carriers
Prevents mix-ups and misidentification
Enables full traceability of samples and reagents
Enhances workflow safety and compliance
Pipetting
MassSTAR ensures highly accurate and reproducible pipetting across all workflow stages. Each aspiration and dispense step is monitored in real time using advanced sensor technology, allowing the system to detect and respond to issues such as clogs, foam, air bubbles, or incorrect volumes.
Real-time monitoring of all pipetting actions
Automatic error handling and sample exclusion
Compatible with various tube formats and labware types
Ensures consistent sample preparation and minimizes manual errors
The heater-shaker
The integrated heater-shaker module plays a key role in homogenization and incubation. It combines precise temperature control with programmable shaking speeds to ensure optimal reaction conditions for every assay.
Ensures uniform mixing and reagent distribution
Supports time-optimized incubation steps
Fully integrated into the automated workflow for walkaway operation
While shaking is in progress, the software executes parallel tasks to maximize efficiency and reduce overall runtime
The CO-RE Gripper
The CO-RE® Gripper is an intelligent transport module that enables safe and efficient movement of labware across the deck. Mounted directly on the waste block, it requires no additional space and operates seamlessly within the automated workflow.
Transports microplates and deep well plates
Picked up directly by the pipetting arm for streamlined operation
Saves deck space and simplifies labware logistics
The centrifuge
A fully integrated centrifuge ensures precise and reproducible separation of sample components. It is seamlessly embedded into the workflow.
Centrifugation of deep-well plates for protein precipitation and extraction
Optimized speed and timing for clinical sample types
Ensures clean supernatant transfer and minimizes matrix effects
Reduces manual handling and improves reproducibility
Operates in parallel with other workflow steps to maximize efficiency
Robust towards imbalance
Further features
Compression-induced O-Ring

Lower Total Cost:
Up to 15 x life span
Simplified serviceability
Reduced preventive maintenance
Total aspiration and dispense monitoring
One of MassSTAR’s key safety features is Total Aspiration and Dispense Monitoring (TADM™), which tracks every pipetting step in real time. This intelligent system ensures accurate sample handling and immediate error detection.
Real-time monitoring of aspiration and dispensing across all channels
Detects clots, foam, short samples, and incorrect volumes
Automatically retries failed pipetting steps or excludes faulty samples
Identifies incorrect reagent usage and system leaks
Provides a complete digital audit trail for full traceability and compliance

MassSTAR allows the sample preparation of 288 samples per batch for vitamin D, 176 for immunosuppressants and 96 for MassTox® TDM Series A. The complete parameter menu has been comprehensively tested. Method comparisons between manual and automated sample preparation clearly demonstrate a high correlation of data. In essence: same results, lower risk of pipetting errors, increased throughput and reduced costs.
