Vitl Ther-mix Programmable Heating and Mixing System

Overview

The Vitl Ther-mix is a programmable heating and mixing system engineered for precision thermal and mechanical control in life science laboratories. Based on Peltier-based active heating/cooling and synchronous orbital shaking, the Ther-mix delivers reproducible, gradient-free temperature uniformity across sample vessels while maintaining consistent mixing kinetics. Unlike conventional heat blocks or vortexers, the Ther-mix integrates independent top-lid and base heating zones—eliminating condensation during prolonged incubation and enabling precise thermal management of sealed tubes and plates. Its core architecture supports fully autonomous execution of multi-step protocols involving dynamic temperature ramps, variable speed mixing, and timed dwell phases—making it suitable for applications where thermal homogeneity, kinetic consistency, and hands-free operation are critical.

Key Features

• Intuitive 4.3-inch capacitive LCD touchscreen interface with multilingual support for protocol creation, editing, and recall
• Dual-zone thermal control: independently regulated base plate (up to 99.9 °C) and heated lid (up to 105 °C) to prevent evaporation and condensation in capped tubes and sealed microplates
• Orbital mixing with 3 mm radius and speed range of 200–3000 rpm (0–80 g load); reduced range of 200–2000 rpm for heavier loads (80–300 g)
• Temperature accuracy of ±1 °C across full operating range (ambient to 105 °C), verified per ISO/IEC 17025 traceable calibration procedures
• Sorbothane™ isolation feet for vibration damping and acoustic noise reduction (<45 dB(A) at 1 m)
• Modular heating platform design: interchangeable, pre-calibrated modules compatible with 0.2 mL PCR tubes, 0.5 mL tubes, 1.5/2.0 mL microcentrifuge tubes, 96-well PCR plates, and deep-well plates
• Onboard storage for over 100 user-defined protocols with timestamped execution logs
• Compliance with IEC 61010-1 for laboratory equipment safety, CE and UKCA marking, and RoHS Directive 2011/65/EU

Sample Compatibility & Compliance

The Ther-mix accommodates standard laboratory consumables without adapter requirements: single tubes (0.2–2.0 mL), tube racks (up to 24 positions), 96-well PCR plates (full- or half-block), and 384-well formats via optional high-density modules. All heating modules undergo factory calibration against NIST-traceable reference standards and are supplied with individual calibration certificates. The system supports GLP/GMP-aligned workflows through audit-trail-enabled protocol logging and user-access controls. While not classified as a medical device under FDA 21 CFR Part 820 or EU MDR, its performance specifications meet ASTM E2927-21 (Standard Practice for Thermal Validation of Laboratory Equipment) and ISO 13485-relevant environmental control criteria when deployed in quality-controlled bioanalytical settings.

Software & Data Management

No external software installation is required—the Ther-mix operates as a standalone instrument with embedded firmware supporting protocol export via USB flash drive (CSV and proprietary .therm format). Each executed run records timestamped metadata including setpoints, actual temperatures (base/lid), rotational speed, elapsed time, and error flags. Logs are retained for ≥10,000 cycles and support manual review or integration into LIMS environments via structured CSV parsing. Firmware updates are delivered via secure HTTPS download and validated using SHA-256 checksums. The system does not transmit data externally by default and contains no wireless interfaces—ensuring compliance with institutional IT security policies and GDPR/CCPA data residency requirements.

Applications

• Enzyme-linked immunosorbent assay (ELISA) plate incubation with simultaneous gentle agitation to enhance antigen–antibody binding kinetics
• PCR master mix preparation and pre-thermal cycling equilibration with controlled ramp rates (0.1–5.0 °C/min)
• Nucleic acid extraction workflows: lysis buffer activation, proteinase K digestion, and silica-magnetic bead binding steps requiring defined temperature–time–shear profiles
• cDNA synthesis and reverse transcription reactions sensitive to thermal overshoot or uneven mixing
• Controlled denaturation and renaturation of DNA, RNA, and proteins under programmable thermal gradients
• Bacterial cell lysis and plasmid miniprep protocols demanding consistent shear stress and temperature stability
• Immunoprecipitation wash steps requiring low-shear mixing at 4 °C or 37 °C
• Cell suspension homogenization prior to flow cytometry analysis
• Antibody–antigen complex formation studies requiring extended incubation with intermittent mixing

FAQ

Is the Ther-mix compliant with FDA 21 CFR Part 11 for electronic records?
No—the Ther-mix does not implement electronic signatures, role-based access control, or audit trail encryption required under Part 11. It may be used in FDA-regulated environments for non-GxP auxiliary tasks; formal validation documentation is available upon request.

Can I use the Ther-mix without a heating module installed?
No—operation requires a mechanically secured heating module. The instrument will not initiate protocols unless a module is detected and properly fastened using the included torque-limited screwdriver.

What is the maximum recommended load per tube position during mixing?
For optimal thermal transfer and mechanical stability, total mass per position should not exceed 300 g—including tube, cap, and liquid volume. Exceeding this limit may reduce speed range and compromise temperature uniformity.

Does the Ther-mix support remote monitoring or network connectivity?
No—it has no Ethernet, Wi-Fi, or Bluetooth interfaces. All interaction occurs locally via touchscreen or USB export. This design prioritizes cybersecurity and electromagnetic compatibility in shared lab infrastructure.

Are calibration certificates provided with each heating module?
Yes—each module ships with a unique serial-numbered calibration certificate showing deviation values at three temperature points (25 °C, 55 °C, and 95 °C), traceable to UKAS-accredited laboratories.
