Roche Cobas C311 or HumaStar 300SR

Throughput
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.

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 testing flexibility, reducing the need for frequent reagent changes.

Both the HumaStar 300SR and the Roche C311 offer the same maximum throughput of 300 tests per hour, making them suitable for medium to high volume laboratories.

The HumaStar 300SR has 40 reagent positions, while the Roche C311 has 42 reagent positions. The Roche C311 has a slight advantage in reagent capacity.

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.

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 keeps reagents stable at 13°C below room temperature. In contrast, the Roche C311 offers a reagent cooling range of 5°C - 15°C.

The HumaStar 300SR offers 60 sample positions, while the Roche C311 offers a significantly higher sample capacity of 110 positions, making it suitable for laboratories with larger sample volumes.

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 high-volume clinical laboratories.

Clot detection
In laboratories where clotting problems are common, clot detection is essential to identify and manage clot-related problems. It ensures the accuracy of results and reduces the need for repeat testing.

The HumaStar 300SR has an internal sample barcode reader, while the Roche C311 also has a sample barcode reader.

The HumaStar 300SR does not have clot detection, while the Roche C311 has clot detection capabilities that can improve the accuracy and reliability of results in laboratories.

Cuvettes
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 the cuvette configuration is important for cost and efficiency considerations.

The HumaStar 300SR uses 80 Bionex reusable cuvettes, providing a higher cuvette capacity, while the Roche C311 uses 66 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, making it more water efficient. In contrast, the Roche C311 has a higher water consumption rate of 12 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.
