Selecting a clinical chemistry analyzer is a crucial decision for laboratories, impacting workflow efficiency, turnaround times, and overall testing accuracy. Both the HumaStar 100 by HUMAN and the Spin 120 by Spinreact are instruments designed for smaller laboratories, but understanding their strengths and weaknesses is essential for making an informed choice. This comprehensive comparison equips you with the knowledge to choose the ideal analyzer for your specific laboratory needs.

Decision Factors


Throughput refers to the number of tests a clinical chemistry analyzer can perform in an hour. A higher throughput translates to faster analysis times, quicker turnaround times for test results, and improved overall laboratory productivity.

  • HumaStar 100: Offers a maximum throughput of 100 tests per hour. This is suitable for smaller laboratories with moderate testing volumes.

  • Spin 120: Provides two throughput options: 100 tests per hour for basic tests. 300 tests per hour when electrolyte testing (ISE) is included.

This flexibility in throughput can be advantageous for laboratories with fluctuating testing demands that occasionally require higher processing speeds.

Reagent Positions

The number of reagent positions on a clinical chemistry analyzer influences its versatility and testing capability. More reagent positions allow laboratories to conduct a wider range of tests without frequent reagent changes, enhancing workflow efficiency and minimizing downtime.

  • HumaStar 100: Provides 30 reagent positions, allowing for a diverse range of tests.

  • Spin 120: Offers 28 reagent positions, which may slightly limit test menu options compared to the HumaStar 100.

Reagent Cooling

Clinical chemistry reagents require specific temperature ranges for optimal performance and accurate test results. A built-in reagent cooling system safeguards reagent integrity and guarantees consistent test outcomes.

  • HumaStar 100: Includes an independent reagent cooling system, ensuring temperatures remain stable even if the main power switch fluctuates.

  • Spin 120: Utilizes a 4-15°C temperature range for reagent storage. While not a full-fledged cooling system, it helps maintain appropriate temperatures.

Sample Positions

The number of sample positions on a clinical chemistry analyzer impacts its capacity to handle fluctuating sample volumes. A sufficient number of positions is essential for efficient sample processing and reducing backlogs.

  • HumaStar 100: Provides 60 sample positions, accommodating laboratories with moderate sample volumes.

  • Spin 120: Offers only 8 sample positions, which is a significant limitation. This analyzer is best suited for laboratories processing low sample volumes or those prioritizing a smaller footprint.

Sample Barcode Reader

  • Importance: An integrated sample barcode reader safeguards against sample mix-ups and guarantees accurate test results linked to the corresponding patients. This feature is particularly advantageous for laboratories processing a moderate number of samples and minimizing the risk of errors.

  • HumaStar 100: Includes an internal sample barcode reader for enhanced accuracy in sample identification and reduced risk of errors.

  • Spin 120: Sample barcode reader is listed as optional, so its availability may need to be confirmed with the supplier and factored into the cost comparison.


Cuvettes are disposable or reusable containers that house the reaction mixture during clinical chemistry testing. The type and quantity of cuvettes influence consumable costs and waste generation.

  • HumaStar 100: Utilizes 80 reusable cuvettes, minimizing consumable costs and environmental impact.

  • Spin 120: Employs 40 disposable cuvettes, leading to higher consumable costs and greater waste generation.

Water Consumption

Water consumption is a growing concern in laboratory management. Clinical chemistry analyzers with lower water consumption rates contribute to cost savings and environmental sustainability efforts.

  • HumaStar 100: Demonstrates a very low water consumption rate of less than 1 liter per hour (8 ml/test).

  • Spin 120: Consumes 2.5 liters of water per hour, significantly higher than the HumaStar 100. This can impact operational costs and environmental footprint.

Both the HumaStar 100 and Spin 120 offer advanced features and reliable performance tailored to meet the evolving needs of modern laboratories. The choice between the two depends on your laboratory's specific requirements, such as testing volume, flexibility, and operational preferences. Consider factors such as throughput, reagent and sample positions, cuvette type, and sample barcode reader integration to make the best decision aligned with your laboratory's goals and priorities.
