Hamilton Microlab ML610-DIS Dispenser

The Microlab ML610-DIS is a specialized single-syringe configuration within the Microlab 600 series. This high-precision dispenser is designed to eliminate the variability of manual pipetting by providing a semi-automated, positive displacement fluid path that excels even with challenging liquids like viscous oils, volatile solvents, or heavy slurries.

The ML610-DIS is a "Single Syringe Dispenser" setup, typically used to dispense precise volumes of a single liquid from a large reservoir into multiple containers.

Technical Highlights

• Single Syringe Drive: The system utilizes one high-resolution syringe drive (48,000 steps over 60 mm) to pull liquid from a source and dispense it with a volume accuracy of ±1%.

• Positive Displacement Technology: Unlike air-displacement pipettes, the syringe plunger makes direct contact with the liquid. This ensures that accuracy is maintained regardless of atmospheric pressure or liquid density.

• Inert Fluid Path: The fluid only comes into contact with chemically resistant materials—specifically borosilicate glass, PTFE, and CTFE—making it suitable for aggressive chemicals and preventing sample contamination.

• Advanced Valve Logic: The ML610-DIS uses a high-precision universal valve that can be configured to handle everything from simple aliquoting to complex reagent additions.

Operational Efficiency

• Guided Software Wizards: The unit is controlled via a sunlight-readable touchscreen. The "Dispense Wizard" allows users to set a volume, prime the system, and begin a run in seconds.

• Ergonomic Hand Probe: The system comes with a lightweight hand probe featuring a trigger button, allowing the operator to focus on the target vessel while the pump handles the measurement.

• Minimized Waste: The Bubble Free Prime (BFP) syringes allow for rapid air removal with minimal reagent loss, which is critical when working with expensive or limited-volume samples.

• Data Logging: Each dispense is logged by the system, ensuring traceability for labs operating under GLP/GMP or ISO quality standards.

Common Applications

• Sample Preparation: Precise addition of reagents or buffers into vials or tubes.

• Reagent Aliquoting: Breaking down bulk chemicals into smaller, usable portions without the risk of cross-contamination.

• Industrial Fill-and-Finish: Semi-automated filling of small batches of product, such as diagnostic kits or cosmetic samples.

• Dose Accuracy: Providing consistent dosing for animal research or pharmaceutical formulation.
