DLAB MX-T6-Pro / MX-T6-S Orbital Roller Mixer

Overview

The DLAB MX-T6-Pro and MX-T6-S Orbital Roller Mixers are precision-engineered laboratory instruments designed for gentle yet effective homogenization of sensitive biological and chemical samples requiring controlled agitation without shear-induced degradation. Unlike vortex mixers or high-speed shakers, these devices employ a dual-motion principle—simultaneous orbital rolling and low-angle rocking—to generate laminar, non-turbulent fluid motion ideal for maintaining sample integrity during prolonged incubation or stabilization protocols. This kinematic profile ensures uniform suspension of particulates, prevents sedimentation in viscous media, and minimizes bubble formation—critical for applications such as anticoagulated blood handling, immunoprecipitation assays, antibody-antigen complex formation, and preparation of cell lysates prior to centrifugation. The MX-T6 series is not a high-shear homogenizer; rather, it functions as a low-energy, reproducible mixing platform optimized for compatibility with standard laboratory tubes (12–15 mm diameter), microcentrifuge tubes, culture flasks, and custom cylindrical vessels up to 50 mL volume.

Key Features

• Dual-mode agitation: Independent control of orbital rolling and rocking motions enables customizable mixing profiles suited to diverse sample viscosities and container geometries.
• Precision speed regulation: MX-T6-Pro offers digitally adjustable speed from 10 to 70 rpm with ±1 rpm repeatability; MX-T6-S provides analog-adjustable range from 0 to 70 rpm for basic operational flexibility.
• Intuitive digital interface (MX-T6-Pro): Backlit LCD display simultaneously shows real-time speed and timer status; programmable timing function supports durations from 1 minute to 19 hours 59 minutes with auto-shutdown.
• Robust mechanical architecture: All-metal chassis, balanced roller shaft assembly, and brushless DC motor ensure long-term stability, minimal vibration transmission, and consistent rotational torque across the full speed range.
• Compliance-ready design: IP21-rated enclosure protects internal electronics from vertically falling drips and solid objects >12.5 mm; meets IEC 61010-1 safety requirements for laboratory electrical equipment.
• Ergonomic footprint: Compact horizontal layout accommodates placement inside refrigerated chambers (5–40 °C ambient), biosafety cabinets, or stacked benchtop configurations without compromising airflow or accessibility.

Sample Compatibility & Compliance

Both models support common labware including polypropylene and glass test tubes (10–50 mL), Eppendorf-style microtubes, and narrow-necked culture bottles. The 24 mm amplitude and fixed 6-roller configuration provide optimal contact surface area for secure retention of upright or angled containers during operation. These instruments are routinely deployed in clinical diagnostics labs performing coagulation studies (e.g., preventing fibrin clot formation in EDTA-treated whole blood), research workflows involving chromatin immunoprecipitation (ChIP), and QC procedures for reagent stability testing. While not certified for ISO 13485 or FDA 21 CFR Part 11 out-of-the-box, the MX-T6-Pro’s digital logging capability (via optional RS232/USB interface firmware upgrade) supports audit-trail generation when integrated into GLP-compliant environments. All units comply with CE marking directives (EMC 2014/30/EU, LVD 2014/35/EU) and RoHS 2011/65/EU material restrictions.

Software & Data Management

The MX-T6-Pro operates via embedded firmware with no external software dependency. Its onboard controller stores last-used parameters (speed and time) across power cycles and features fail-safe thermal monitoring that halts operation if internal temperature exceeds safe thresholds. Though native data export is not supported, the device includes a TTL-level serial output port compatible with third-party LabVIEW or Python-based acquisition scripts for integration into automated lab systems. For regulated environments, users may implement procedural controls—including operator ID logging, calibration verification logs, and preventive maintenance records—as part of broader instrument qualification (IQ/OQ/PQ) documentation. The MX-T6-S lacks digital interfacing but maintains identical mechanical performance for settings where traceability is managed manually.

Applications

• Anticoagulant-dependent hematology workflows: Maintaining homogeneous distribution of blood cells during transport or pre-analytical holding periods.
• Immunoprecipitation and pull-down assays: Enhancing binding kinetics between target antigens and immobilized antibodies under mild agitation.
• Enzyme reaction incubations: Facilitating substrate-enzyme interaction in low-viscosity buffers without denaturation risks associated with vigorous shaking.
• Standard curve preparation: Ensuring uniform dilution series for ELISA, PCR master mixes, or calibration standards.
• Cell culture maintenance: Gentle resuspension of adherent cells post-trypsinization prior to counting or plating.
• Pharmaceutical excipient blending: Homogenizing suspensions of insoluble APIs in vehicle matrices during early-stage formulation development.

FAQ

Can the MX-T6-Pro be used inside a cold room at 4 °C?
No—the specified operating ambient temperature range is 5–40 °C. Prolonged use below 5 °C may affect motor efficiency and LCD responsiveness.

Is the roller angle adjustable?
No—the rocking angle is fixed at 6° to ensure consistent motion kinematics and prevent tube ejection during extended runs.

What is the maximum tube diameter supported?
Tubes up to 18 mm outer diameter can be securely held; wider containers require custom roller inserts (available separately).

Does the MX-T6-S include any form of speed calibration certificate?
DLAB provides factory calibration verification per unit, documented in the shipping dossier; NIST-traceable recalibration services are available upon request.

Can both models accommodate tilted tube orientation?
Yes—rollers are mounted on a pivoting base allowing manual adjustment between 0° (horizontal) and 10° inclination for enhanced mixing dynamics in low-volume samples.
