Molecular Devices AquaMax 4000 Washer

The Molecular Devices AquaMax 4000 is a fully automated, self-contained microplate washer designed for biochemical assays, cellular research, and enzyme-linked immunosorbent assays (ELISA). Equipped with a dedicated 96-well wash head, the instrument delivers precise liquid dispensing and rapid aspiration without requiring external pumps or vacuum supplies.

Molecular Devices AquaMax 4000 Washing Capabilities

The AquaMax 4000 provides high washing efficiency while maintaining low residual volume per well. Key operational features include:

• Low Residual Volume: Precise aspiration needles reduce residual fluid to less than 2 µL per well. Consequently, it minimizes assay background noise and enhances signal-to-noise ratios.
• Gentle Cell Washing: Operators can fine-tune dispensing rates, aspiration angles, and probe heights. Therefore, the system preserves adherent cell monolayers during delicate cell-based assays.
• Multiple Wash Head Compatibility: While configured with a 96-well wash head, the base unit easily accepts interchangeable 384-well heads. As a result, laboratories can scale throughput without replacing the main chassis.
• Flexible Wash Protocols: The unit supports bottom washing, crosswise aspiration, and custom soak cycles. In addition, users can program multi-step wash sequences tailored to specific reagent chemistries.

Molecular Devices AquaMax 4000 Hardware and Interface

Engineered with an all-in-one footprint, the AquaMax 4000 integrates internal pumps and fluid controls directly into the benchtop unit.

Primary hardware components include:

• Standalone Touchscreen Display: A high-resolution color touchscreen eliminates the need for an external computer. Specifically, users can create, edit, and store complete protocols directly on the device.
• Automated Maintenance Cycles: Built-in rinse routines prevent salt accumulation and clogs within the dispense manifold. Furthermore, automated shutdown protocols maintain system readiness between runs.
• Liquid Level Sensing: Integrated sensors in the fluid reservoir bottles monitor wash buffers and waste levels. Thus, the system prevents dry runs and waste bottle overflows during unattended operation.

Data Management and Laboratory Applications

The unit offers comprehensive protocol storage and user management settings to ensure reproducible assay conditions across multiple operators. Furthermore, USB connectivity enables rapid protocol backup and transfer across instruments.

Ultimately, the Molecular Devices AquaMax 4000 supports routine workflows in pharmaceutical discovery, academic biology, clinical diagnostics, and high-throughput screening laboratories requiring dependable, repeatable microplate processing.
