Hamilton Microlab ML620-DIS

The Microlab ML620-DIS is the premium single-syringe configuration in the Microlab 600 series. While it shares the same high-precision mechanical hardware as the ML610, the "620" designation identifies it as the Advanced model. It is designed for laboratories that require not just precision dispensing, but also enhanced data security, custom programmability, and full compliance with stringent regulatory environments.

The "Advanced" Advantage

The primary difference between the ML610 and the ML620 lies in the software capabilities. The ML620-DIS provides full access to the most sophisticated features of the Microlab 600 controller:

• Custom Method Programming: Unlike the standard model, the ML620 allows users to create and save highly complex, multi-step liquid handling sequences beyond simple dispensing.

• Enhanced Security: It features multi-user login with tiered access levels (Administrator vs. Operator), ensuring that validated protocols cannot be altered by unauthorized personnel.

• Compliance Ready: It is fully equipped for FDA 21 CFR Part 11 and GLP/GMP environments, featuring an unalterable electronic audit trail that tracks every action and dispense event.

Core Technical Specifications

• Single Syringe Drive: Features a high-torque motor with 48,000-step resolution, providing ultra-fine control for volumes from 10 µL to 50 mL.

• Positive Displacement: By using Hamilton’s precision syringes, the system maintains ±1% accuracy and 0.2% precision, unaffected by the liquid's viscosity, temperature, or vapor pressure.

• Universal Valve System: The high-speed valve allows for rapid switching between filling and dispensing, minimizing the fluid path's dead volume.

• Inert Materials: Every component in the fluid path is crafted from borosilicate glass, PTFE, or CTFE, ensuring compatibility with virtually any chemical or solvent.

Operational Features

• Smartphone-Style Interface: A 5.7-inch color touchscreen provides an intuitive environment for managing methods.

• Large Storage Capacity: The ML620 can store up to 2 GB of methods and log files, which can be easily exported via the integrated SD card slot or USB port for external reporting.

• Bubble Free Prime (BFP): Specialized syringe designs allow for nearly instantaneous priming with zero air bubbles, saving expensive reagents and time.

Ideal Applications

• Regulated Laboratories: Pharmaceutical and clinical labs that must comply with strict auditing and security protocols.

• R&D Environments: Where complex, custom-programmed liquid handling routines are necessary for experimental consistency.

• Precision Aliquoting: Reliable, high-accuracy distribution of expensive reagents, standards, or volatile organic compounds.
