Choosing the right clinical chemistry analyzer is critical for laboratories that want to deliver accurate and timely results. The Urit 8280 and HumaStar 600 are both top contenders on the market, offering a range of features designed to meet different laboratory needs. This article will provide a comprehensive comparison of these two systems, examining their throughput, reagent management, sample processing capabilities, and environmental impact. Our goal is to provide you with the information you need to make an informed decision about which system best suits your laboratory's needs.

When selecting a clinical chemistry analyzer, it's important to consider several factors to ensure the system meets the operational and diagnostic needs of your laboratory. The Urit 8280 and HumaStar 600 each offer unique advantages. Here, we compare these systems based on key considerations.

Throughput Max. Tests/Hour

High throughput is essential for laboratories to efficiently process large volumes of tests, improving turnaround times and patient care.

  • Urit 8280: With a maximum throughput of 640 tests per hour, the Urit 8280 is well suited for high-volume laboratories that need to process large numbers of samples quickly.
  • HumaStar 600: Offers throughput of up to 600 tests per hour, making it a competitive option for mid- to high-volume laboratories seeking a balance between efficiency and accuracy.

Reagent Positions

The number of reagent positions affects the laboratory's ability to offer a wide range of tests simultaneously, thereby increasing diagnostic capabilities.

  • Urit 8280: Features 80 reagent positions, providing ample capacity for a diverse test menu, ideal for laboratories that require versatility in their diagnostic offerings.
  • HumaStar 600: Equipped with 48 reagent positions, allowing for simultaneous testing of multiple parameters and enhancing operational efficiency.

Reagent Cooling

Proper reagent cooling is critical to maintaining reagent stability and ensuring accurate test results, especially for temperature-sensitive assays.

  • Urit 8280: Provides reagent cooling at 2-8℃, maintaining reagent integrity and ensuring reliable results over a range of test conditions.
  • HumaStar 600: Maintains reagent cooling at 9°C ± 2°C, ensuring optimal temperature control throughout testing.

Sample Positions

Sample position capacity directly affects workflow efficiency by determining how many samples can be processed at one time.

  • Urit 8280: With 99 sample positions, it supports efficient sample throughput, reducing the need for frequent reloading and accommodating peak laboratory workloads.
  • HumaStar 600: Provides 95 sample positions, facilitating efficient sample processing and workflow management.

Sample Barcode Reader

An internal barcode reader improves sample tracking accuracy, reduces manual errors and streamlines laboratory operations.

  • Both the Urit 8280 and HumaStar 600 include internal sample barcode readers, underscoring their commitment to accuracy and efficiency in sample processing.


The type and number of cuvettes affect the analyzer's operational efficiency and the laboratory's environmental footprint.

  • Urit 8280: Uses 120 semi-permanent cuvettes, striking a balance between reducing consumable waste and maintaining testing efficiency.
  • HumaStar 600: Utilizes 160 reusable cuvettes, promoting sustainability and cost-effectiveness in laboratory operations.

Water Consumption (L/H)

Importance: Water consumption has an impact on the environmental impact and operating costs of the analyzer, with lower consumption indicating a more efficient system.

  • Urit 8280: Consumes less than 25 liters per hour, aiming for efficiency while keeping operating costs in mind.
  • HumaStar 600: Consumes less than 5 liters of water per hour, contributing to cost efficiency and environmental sustainability.


In summary, both the Urit 8280 and HumaStar 600 offer compelling features for clinical chemistry testing. The choice between them should be based on your laboratory's specific needs, such as test volume, range of assays required, operational efficiency, and commitment to sustainability. While the Urit 8280 excels in throughput and sample capacity, making it suitable for high-volume laboratories, the HumaStar 600 is a strong contender for laboratories focused on efficiency and environmental sustainability. Carefully consider your lab's priorities to select the system that best supports your diagnostic capabilities and operational goals.
