Is critical for laboratories with varying sample volumes. A high-throughput analyzer is appropriate for high-volume testing environments, while lower throughput analyzers may be sufficient for smaller labs. Choosing the right throughput is critical to meeting the lab's testing needs without bottlenecks or underutilization.

The HumaStar 300SR offers a higher maximum throughput of 300 tests per hour, while the Mindray BS-240 has a maximum throughput of 200 tests per hour.

Reagent Positions

The availability of reagent positions is critical for laboratories that need to perform a wide range of tests. A higher number of positions allows for more test flexibility, reducing the need for frequent reagent changes.

The HumaStar 300SR has 40 reagent positions, while the Mindray BS-240 has 80 reagent positions, offering a wider range of reagents.

Reagent cooling

Stable reagents are essential for accurate and reliable test results. Reagent cooling helps maintain reagent integrity, especially for tests that are sensitive to temperature fluctuations.

The HumaStar 300SR maintains reagents at 13°C below room temperature for stability, while the Mindray BS-240 offers a reagent cooling range of 2°C - 12°C.

Sample Positions

Adequate sample positions are critical for laboratories with varying sample volumes. Sufficient sample positions ensure that all patient samples can be processed efficiently, reducing the risk of sample backlogs.

The HumaStar 300SR has a larger sample capacity of 60 positions, while the Mindray BS-240 offers 40 sample positions.

Sample Barcode Reader

Improve the integrity of the testing process by reducing the risk of sample mix-ups and ensuring that results are accurately linked to the appropriate patient. This is especially important for clinical laboratories with high sample throughput.

The HumaStar 300SR comes with an internal sample barcode reader, making sample identification easier, while the Mindray BS-240 offers a sample barcode reader as an optional feature.


The type and capacity of cuvettes affect the cost of consumables, the number of tests that can be performed before cuvette replacement, and the environmental impact. Understanding cuvette configuration is important for cost and efficiency considerations.

The HumaStar 300SR uses 80 Bionex reusable cuvettes, providing a larger cuvette capacity, while the Mindray BS-240 uses 40 reusable cuvettes.

Water Consumption

Monitoring water consumption is important for controlling operating costs and minimizing environmental impact. Reducing water consumption can result in cost savings and contribute to sustainability efforts in the laboratory.

The HumaStar 300SR has a lower water consumption rate of less than 3 liters per hour, which is more water efficient compared to the Mindray BS-240 with a water consumption of ≤ 4 liters per hour.

In summary, the HumaStar 300SR is a compelling option for laboratories with larger sample volumes. Its outstanding feature is the significantly higher sample capacity, which meets the requirements of high-throughput laboratories. It also has the added benefit of lower water consumption, which not only reduces operating costs but also contributes to a more environmentally friendly laboratory.

Your decision between these two clinical chemistry analyzers should be based on your laboratory's specific priorities, such as test diversity, sample volume, water consumption, and the importance of clot detection in your testing processes.
