When it comes to selecting the right clinical chemistry analyzer for your laboratory, thorough comparison is essential. In this comprehensive review, we'll compare the features and specifications of two prominent analyzers: the HumaStar 100 by HUMAN and the ChemWell 2 by Awareness Technology, aiding you in making an informed decision for your laboratory's testing needs.


Efficiency in sample processing is paramount for laboratories with high testing volumes. Let's see how these analyzers stack up in terms of throughput:

  • HumaStar 100: Offers a maximum throughput of 100 tests per hour, ensuring timely results for laboratories with moderate to high testing demands.
  • ChemWell 2: Matches the HumaStar 100 with a throughput of 100 tests per hour, providing efficient sample processing capabilities for laboratories of various sizes.

Reagent Positions

The availability of reagent positions directly impacts the analyzer's capacity to perform a diverse range of tests without frequent reagent changes:

  • HumaStar 100: Equipped with 30 reagent positions, allowing for a wide array of tests to be conducted without compromising efficiency.
  • ChemWell 2: Does not specify reagent positions, which may limit its ability to accommodate a broad range of tests simultaneously.

Reagent Cooling

Maintaining stable reagent temperatures is crucial for accurate test results. Let's compare the cooling mechanisms of these analyzers:

  • HumaStar 100: Features independent reagent cooling, ensuring optimal temperature control and stability throughout testing.
  • ChemWell 2: Maintains reagent temperature between 8-12°C, providing adequate cooling to preserve reagent integrity and ensure reliable test results.

Sample Positions

Sufficient sample positions are essential for managing diverse sample volumes efficiently:

  • HumaStar 100: Offers 60 sample positions, enabling efficient sample processing and workflow optimization.
  • ChemWell 2: Does not specify sample positions, potentially limiting its capacity to handle varying sample volumes effectively.

Sample Barcode Reader

Integration of a sample barcode reader enhances testing accuracy and traceability:

  • HumaStar 100: Includes an internal sample barcode reader, ensuring seamless sample identification and result linkage.
  • ChemWell 2: Offers an optional sample barcode reader, providing flexibility in sample identification methods.


The type and capacity of cuvettes impact operational costs and testing efficiency:

  • HumaStar 100: Utilizes 80 reusable cuvettes, promoting sustainable laboratory practices and minimizing waste.
  • ChemWell 2: Does not specify cuvette information, necessitating further clarification regarding its cuvette type and capacity.

Water Consumption

Monitoring water consumption is essential for sustainable laboratory management:

  • HumaStar 100: Consumes less than 1 liter of water per hour (8 ml/test), contributing to cost efficiency and environmental sustainability.
  • ChemWell 2: Does not specify water consumption, requiring additional information to assess its environmental impact and operational costs.

Both the HumaStar 100 and ChemWell 2 offer advanced features and reliable performance tailored to meet the diverse needs of modern laboratories. The choice between the two depends on your laboratory's specific requirements, such as throughput, reagent and sample positions, cooling mechanisms, sample barcode reader integration, cuvette type, and water consumption.
