Description

The BIOBASE 4001 is a high-performance, fully automated immunoassay analyzer designed to meet the rigorous demands of large-scale laboratories. Equipped with four sampling channels, advanced liquid handling capabilities, multiple incubators, and integrated safety features, it delivers exceptional precision, efficiency, and flexibility for high-throughput ELISA testing.

Key Features

1. Pressure-Based Liquid Detection: Air pressure-based technology for precise liquid level and clot detection.

2. High-Precision Pipetting: Delivers volumes as low as 5 μL with exceptional accuracy and repeatability.

3. Real-Time Gripper Monitoring: Position sensing with adjustable spacing and strength to handle various plate sizes and covers.

4. TIP Detection & Clot Monitoring: Ensures accurate sampling and minimizes cross-contamination.

5. Dual Thread Control: Allows simultaneous operation of sampling and handling units without interference.

6. Expanded Capacity: 12 incubators and 4 sampling channels boost throughput for high-volume labs.
