LabTech M64 Automated High-Throughput Parallel Concentrator

Overview

The LabTech M64 Automated High-Throughput Parallel Concentrator is an engineered solution for quantitative solvent removal in analytical laboratories requiring reproducible, multi-sample preparation under controlled thermal and gas-flow conditions. It operates on the principle of simultaneous nitrogen-assisted evaporation combined with precise water-bath temperature regulation—commonly applied in sample prep workflows prior to GC, LC-MS, ICP-MS, and environmental residue analysis. Unlike single-channel concentrators, the M64 supports true parallel processing across up to 64 independent sample positions, significantly reducing batch processing time while maintaining inter-channel consistency. Its modular architecture separates the heating and gas delivery subsystems from the sample-holding racks, enabling flexible adaptation to diverse container geometries without mechanical retrofitting. Designed for routine use in QC/QA labs, environmental testing facilities, and contract research organizations, the M64 meets fundamental operational requirements for method robustness, operator safety, and traceable process control.

Key Features

• 64-channel parallel concentration capability with individual channel independence and uniform thermal/gas exposure
• Programmable water bath heating (range: ambient to 100 °C, ±0.5 °C stability) with real-time digital monitoring
• Motorized vertical positioning system for nitrogen manifold—automatically lowers during sample loading and raises during concentration
• Quick-swap nitrogen needle cartridge design: enables rapid reconfiguration between 12-, 24-, 48-, and 64-position layouts; unused ports sealed via inert polymer blind plugs
• Integrated illuminated viewing window with front-access transparent panel—enables continuous visual monitoring without lid opening or process interruption
• Multi-layer safety architecture including water level sensor, pressure transducer feedback loop, and motor current monitoring for overload detection
• Color touchscreen HMI with intuitive workflow navigation, parameter logging, and status visualization (temperature, gas flow, elapsed time, alarm history)
• Modular rack interface supporting standard 12 × 75 mm, 15 mL, 50 mL conical, and custom-fabricated tube formats (available upon specification submission)

Sample Compatibility & Compliance

The M64 accommodates a broad range of sample containers—from microcentrifuge tubes (2 mL) to large-volume glass vials (200 mL)—through interchangeable, laser-cut aluminum or PTFE-coated stainless steel racks. All rack designs comply with ISO 8573-1 purity class 4 for compressed air/nitrogen pathways when used with certified lab-grade gas sources. The instrument’s mechanical and electrical construction adheres to IEC 61010-1:2010 safety standards for laboratory equipment. While not inherently 21 CFR Part 11 compliant out-of-the-box, audit trail functionality—including user login timestamps, parameter change logs, and run completion records—can be enabled via optional firmware upgrade to support GLP/GMP-aligned documentation practices. No hazardous materials are employed in its structural assembly; all wetted parts are chemically resistant to common organic solvents (e.g., acetonitrile, methanol, ethyl acetate, hexane).

Software & Data Management

The embedded control system runs on a real-time Linux kernel with deterministic I/O response. All operational parameters—including setpoint temperature, nitrogen flow rate (via integrated mass flow controller), ramp profiles, hold times, and endpoint criteria—are configurable per run. The interface stores up to 1,000 method templates locally, each associable with user-defined metadata (e.g., analyst ID, project code, SOP reference). Data export is supported via USB 2.0 port in CSV format, compatible with LIMS integration and statistical process control (SPC) platforms. Optional Ethernet connectivity enables remote monitoring and centralized fleet management through LabTech’s LabControl Suite, which provides role-based access control, electronic signature support, and automated backup to network drives—facilitating alignment with ISO/IEC 17025 documentation requirements.

Applications

• Residue analysis in food and agricultural commodities (e.g., pesticide multiresidue methods per AOAC 2007.01 and EN 15662)
• Environmental water and soil extract cleanup prior to GC-ECD or LC-MS/MS quantification
• Pharmaceutical impurity profiling and stability-indicating assay sample prep (aligned with ICH Q2(R2) guidance)
• Forensic toxicology sample concentration for blood, urine, and tissue extracts
• High-throughput clinical biomarker discovery workflows involving plasma/serum derivatization
• Standard addition calibration series preparation with volumetric precision maintained across all 64 channels

FAQ

What is the maximum recommended nitrogen pressure for optimal evaporation efficiency without splashing?
The M64 is calibrated for operation at 0.1–0.3 MPa (1–3 bar) inlet pressure; typical method development uses 0.2 MPa for 15 mL tubes containing 10 mL of ethyl acetate.
Can the instrument be validated for regulated environments?
Yes—IQ/OQ protocols are available from LabTech; PQ execution requires site-specific test samples and documented acceptance criteria per internal SOP.
Is third-party software integration supported?
The device exposes a documented ASCII command set over RS-232 and TCP/IP, enabling integration with CDS, ELN, and MES systems via middleware.
How often does the water bath require maintenance?
Deionized water should be replaced weekly; annual descaling using citric acid solution is recommended if operating above 60 °C for extended durations.
Does the M64 support gradient temperature programming?
No—it maintains a single user-defined setpoint per run; multi-step thermal profiles require external sequencing via method chaining in the control software.
