When selecting a clinical chemistry analyzer for your laboratory, it's important to understand its key features and functions. This comparison highlights the specifications of the HumaStar 200 and NormaChem 200 to aid in your decision-making process and ensure optimal performance for your laboratory.


Efficient throughput is critical for laboratories that need to process a high volume of tests in a given time frame. Throughput indicates the number of tests a clinical chemistry analyzer can perform per hour, directly impacting workflow efficiency and turnaround times.

  • HumaStar 200: Provides a maximum throughput of 200 tests per hour.
  • NormaChem 200: Offers a higher throughput of 275 tests per hour, making it suitable for high-volume laboratories.

Reagent positions

The number of reagent positions available on a clinical chemistry analyzer determines its testing flexibility and the variety of assays it can perform without the need for frequent reagent changes. A higher number of reagent positions can optimize workflow efficiency by reducing the frequency of manual intervention.

  • HumaStar 200: Offers 30 reagent positions.
  • NormaChem 200: Offers 44 reagent positions, providing additional capacity for diverse testing needs.

Reagent cooling

Maintaining stable reagent temperatures is critical to ensuring accurate and reliable test results. Proper reagent cooling mechanisms help maintain reagent integrity and prevent degradation, thereby increasing the accuracy of test results.

  • HumaStar 200: Provides independent reagent cooling to ensure stable reagent conditions.
  • NormaChem 200: Provides 24-hour non-stop cooling to maintain optimal temperature conditions for accurate results.

Sample Positions

Adequate sample positions are critical for effective sample volume management, especially in laboratories that handle varying sample volumes. Sufficient sample positions can optimize workflow efficiency and prevent sample processing bottlenecks.

  • HumaStar 200: Provides 60 sample positions to efficiently accommodate varying sample volumes.
  • NormaChem 200: Offers 44 sample positions, suitable for laboratories with moderate sample processing requirements.

Sample Barcode Reader

Integration of a sample barcode reader increases test accuracy and traceability by ensuring accurate sample identification and result linkage. This feature minimizes the risk of sample mix-ups and improves the overall integrity of the testing process.

  • Both the HumaStar 200 and NormaChem 200 include an internal sample barcode reader for accurate sample identification and traceability.


The type and capacity of cuvettes used in a clinical chemistry analyzer can impact operating costs and environmental sustainability. Reusable or semi-permanent cuvettes promote cost-effective testing and minimize waste generation, contributing to sustainable laboratory practices.

  • HumaStar 200: Uses 80 reusable cuvettes.
  • NormaChem 200: Uses 48 cuvettes with automatic cleaning, ensuring cleanliness and efficiency in the testing process.

Water Consumption

Monitoring water consumption is critical for sustainable laboratory management, as excessive water use can lead to increased operating costs and environmental impact. Clinical chemistry analyzers with low water consumption contribute to resource efficiency and sustainability.

  • HumaStar 200: Demonstrates low water consumption of less than 2 liters per hour.
  • NormaChem 200: Water consumption information not available.


Both the HumaStar 200 and the NormaChem 200 offer advanced features to meet the evolving needs of today's laboratories. The choice between the two depends on your laboratory's specific requirements, such as test volume, versatility, and workflow preferences. Consider factors such as throughput, reagent and sample locations, reagent cooling mechanisms, sample barcode reader integration, cuvette type, and water consumption to make the best decision based on your laboratory's goals and priorities.
