• HumaStar 300SR: The HumaStar 300SR offers a significantly higher maximum throughput of 300 tests per hour, making it more suitable for labs with higher testing volumes.

Reagent Positions:

• ELITechGroup Selectra Junior: Providing 15 reagent positions, the Selectra Junior is suitable for labs with a limited range of tests.

• HumaStar 300SR: With 40 reagent positions, the HumaStar 300SR offers more flexibility in testing, accommodating a broader range of tests.

Reagent Cooling:

• ELITechGroup Selectra Junior: The Selectra Junior features reagent cooling at 10°C, maintaining stable temperatures for reagent integrity.

• HumaStar 300SR: The HumaStar 300SR maintains reagents at 13°C below room temperature, ensuring stability for accurate and consistent test results.

Sample Positions:

• ELITechGroup Selectra Junior: Offering 25 sample positions, the Selectra Junior is suitable for labs with lower to moderate sample volumes.

• HumaStar 300SR: With a larger sample capacity of 60 positions, the HumaStar 300SR is well-suited for labs with higher sample volumes.

Sample Barcode Reader:

• ELITechGroup Selectra Junior: The sample barcode reader is optional, providing flexibility for labs to choose this feature based on their needs.

• HumaStar 300SR: The HumaStar 300SR comes with an internal sample barcode reader, contributing to accurate sample identification.

Cuvettes:

• ELITechGroup Selectra Junior: The Selectra Junior uses 48 semi-disposable cuvettes, offering a balance between reusability and disposability.

• HumaStar 300SR: Utilizing 80 re-usable Bionex cuvettes, the HumaStar 300SR provides a larger cuvette capacity, potentially reducing the frequency of cuvette replacements and offering flexibility in testing.

Water Consumption:

• ELITechGroup Selectra Junior: With a water consumption rate of 0.7 liters per hour, the Selectra Junior is efficient in water usage.

• HumaStar 300SR: The HumaStar 300SR has a very low water consumption rate of less than 3 liters per hour, contributing to operational cost efficiency and environmental sustainability.

Considerations:

• Throughput: The HumaStar 300SR has a significantly higher throughput, making it more suitable for labs with higher testing volumes.

• Reagent Positions: The HumaStar 300SR provides more reagent positions, offering increased flexibility in testing.

• Temperature Control: Both analyzers have reagent cooling features to maintain stable temperatures for accurate test results.

• Sample Tracking: The HumaStar 300SR comes with an internal sample barcode reader, enhancing sample identification accuracy.

• Cuvettes: Laboratories need to consider the type and capacity of cuvettes based on their preferences and cost considerations.

• Water Consumption: Both analyzers have low water consumption rates, contributing to operational cost efficiency and environmental sustainability. The ELITechGroup Selectra Junior has a slightly higher water consumption rate.
