Mindray BS-240 Fully Automated Chemistry Analyzer

The Mindray BS-240 is a compact, fully automated, benchtop clinical chemistry analyzer designed to meet the diverse needs of small to medium-sized laboratories. Despite its small footprint, it offers robust functionality and advanced features, making it an optimal solution for laboratories with varying test volumes.

Key Features:

• Compact Design: The BS-240 is one of the smallest 200 tests per hour (T/H) throughput automatic chemistry analyzers available, saving valuable laboratory space. It provides 40 positions for samples and 40 positions for reagents, with 40 of these positions being interchangeable to extend capacity as needed.

• High Throughput: Capable of processing up to 200 photometric tests per hour, with the option to increase to 400 tests per hour when equipped with an Ion-Selective Electrode (ISE) module.

• Efficient Operation: Features a minimum reaction volume of 100 μL, reducing reagent consumption and operational costs.

• Advanced Sampling Technology: Incorporates smart-sampling technology that enables automatic hemolysate preparation for Hemoglobin A1c (HbA1c) testing, enhancing productivity and accuracy.

• User-Friendly Interface: Equipped with intelligent software and a user-friendly interface, the BS-240 simplifies operation and maintenance, including step-by-step maintenance guides.
