Selecting a clinical chemistry analyzer is a crucial decision for laboratories, impacting workflow efficiency, turnaround times, and overall testing accuracy. Both the HumaStar 200 by HUMAN and the XL-200 by ERBA Mannheim are capable instruments, 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.


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 200 & ERBA XL-200: Both analyzers offer a maximum throughput of 200 tests per hour. This is suitable for mid-sized laboratories managing moderate to high testing volumes.

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.

  • ERBA XL-200: Provides 50 reagent positions, accommodating a broader test menu without frequent reagent changes, offering greater flexibility.

  • HumaStar 200: Provides 30 reagent positions, allowing for a diverse range of tests.

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

  • ERBA XL-200: Utilizes an 8-12°C air cooler for reagent cooling.

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 200: Provides 60 sample positions, accommodating laboratories with moderate to high sample volumes or fluctuating sample loads.

  • ERBA XL-200: Offers 39 sample positions, which may be limiting for laboratories processing high sample volumes.

Sample Barcode Reader

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 high-throughput laboratories processing a large number of samples and minimizing the risk of errors.

  • HumaStar 200: Includes an internal sample barcode reader for enhanced accuracy in sample identification and reduced risk of errors.

  • ERBA XL-200: 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 200: Utilizes 80 reusable cuvettes, minimizing consumable costs and environmental impact.

  • ERBA XL-200: Employs 45 reusable cuvettes.

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 200: Demonstrates a low water consumption rate of less than 2 liters per hour.

  • ERBA XL-200: Consumes 6 liters of water per hour, significantly higher than the HumaStar 200. This can impact operational costs and environmental footprint.


Both the HumaStar 200 and ERBA XL-200 are capable clinical chemistry analyzers. The ideal choice for your laboratory depends on your specific needs and priorities.
