MiniLab5000-L automated sample liquid handling system

Automation & Robotics · 2 models

Liquid handling is where analytical variability starts. A dilution made in a volumetric flask, a standard pipetted by hand, a vial left open while the autosampler waits: each step adds scatter that appears later as an out-of-control quality-control point. The MiniLab5000 line moves those steps onto a benchtop platform with an industrial weighing module, a machine-vision volume module and automated capping, so the analyst sets up a method rather than a sequence of transfers.

±0.1 µL by weight

An industrial weighing module dispenses by gravimetric measurement, with stated accuracy of ±0.1 µL.

Machine-vision volume

Vision-based constant volume works with digestion tubes, volumetric flasks and centrifuge tubes, not one vessel type.

Eight solvents and more

Multi-channel reagent addition handles more than eight solvents within a single preparation sequence.

Dual-station capping

Two capping stations double throughput and accept 2 mL vials, blood tubes, headspace vials and centrifuge tubes.

Models

Choose the configuration.

Two systems share that architecture. MiniLab5000-L covers the broader preparation sequence, from weighing and solid-liquid dissolution through aliquoting, dilution, extraction, filtration, heating and liquid-liquid extraction. MiniLab5000-T concentrates on dilution and constant volume: it uses machine vision to judge the fill level and the titration endpoint, adds indicator, internal standard or diluent, vortexes, and can run a color titration through to a result.

MiniLab5000-L

Automated liquid handling system for sample preparation

MiniLab5000-L automates the liquid preparation steps that precede an analytical run, covering weighing, dissolution, aliquoting, dilution, extraction, filtration, heating and liquid-liquid extraction in one sequence. It is built for laboratories that handle a mix of liquid and dissolved solid samples, including viscous ones, and want the preparation record to sit with the method rather than with an individual analyst.

MiniLab5000-T

Automated dilution and constant-volume system

MiniLab5000-T brings samples to volume and prepares their dilutions automatically. A machine-vision module judges the fill level in digestion tubes, volumetric flasks and centrifuge tubes, while the platform caps and uncaps vials, adds diluent, indicator or internal standard, and vortexes or shakes. An optional color titration package extends it to endpoint determination with automatic result output.

Questions

Before you buy.

What is the difference between MiniLab5000-L and MiniLab5000-T?

MiniLab5000-L is the broader preparation platform: weighing, dissolution, aliquoting, dilution, extraction, filtration, heating and liquid-liquid extraction. MiniLab5000-T is built around dilution and constant volume, adding machine-vision fill-level detection, indicator and internal standard addition, and optional color titration to an endpoint.

Can the platform handle viscous, volatile or hygroscopic samples?

Vortex and vertical shaking cover samples from 0 to 200,000 cps, and the liquid handling system is described as suitable for high-viscosity work. Vials are capped automatically between steps, which keeps volatile and moisture-sensitive samples closed while the run continues.

Does the system work with both acids and organic solvents?

The working chamber is built from PP polypropylene sheet of the type used in ultra-clean fume hoods, with exposed metal parts protected by PTFE and similar coatings, and the material is described as resistant to both acids and organic reagents. More than eight solvents can be added on separate channels.
