Overview
The Titan SD2-100 Refrigerated Vortex Mixer is an engineered platform for precise temperature-controlled sample agitation in research and quality control laboratories. Unlike standard vortex mixers, the SD2-100 integrates active refrigeration with high-stability orbital shaking to maintain samples within a defined low-temperature range during homogenization—critical for thermolabile biomolecules, enzymatic reactions, cell suspensions, and reagent stabilization. It operates on the principle of eccentric orbital motion (vortexing) combined with Peltier-based cooling, enabling rapid thermal equilibration without external chillers or ice baths. The system is designed for continuous operation under ambient conditions up to 30 °C and delivers consistent mixing performance across a wide range of tube formats—including 0.2 mL PCR strips, 1.5 mL microcentrifuge tubes, and 15 mL conical tubes—while maintaining temperature stability ±0.5 °C at setpoints between 4 °C and 30 °C. Notably, the heating module is excluded from this configuration; the unit functions exclusively as a refrigerated mixer.
Key Features
- Peltier-driven refrigeration system with real-time PID temperature regulation and digital display
- Adjustable vortex speed range: 500–3,000 rpm with fine-tuned increment control (10 rpm steps)
- Orbital shaking motion (3 mm amplitude) optimized for uniform suspension without foaming or shear-induced denaturation
- Integrated safety features including over-temperature protection, motor stall detection, and automatic shutdown after 999-minute timer expiration
- Compact benchtop footprint (240 × 220 × 180 mm) with corrosion-resistant aluminum housing and non-slip silicone base
- Modular design supporting optional accessories: universal tube holders, deep-well plate adapters, and programmable timer kits
Sample Compatibility & Compliance
The SD2-100 accommodates standard laboratory consumables used in molecular biology, clinical diagnostics, and pharmaceutical QC workflows. Tube compatibility includes polypropylene, polycarbonate, and glass vials rated for low-temperature storage. Its operational parameters align with common procedural requirements outlined in ISO 15197 (in vitro diagnostic devices), CLSI EP15-A3 (precision evaluation), and USP (endotoxin testing preparation). While not certified to GLP or GMP standards out-of-the-box, the device supports audit-ready documentation when paired with validated SOPs and calibration logs per ISO/IEC 17025 guidelines. Temperature accuracy is verified using NIST-traceable thermistors during factory calibration; users are advised to perform periodic verification using calibrated reference probes.
Software & Data Management
This model operates via embedded firmware with no proprietary software dependency. All settings—including speed, temperature setpoint, and run duration—are configured directly through the front-panel keypad and LCD interface. A built-in non-volatile memory retains the last-used parameters across power cycles. For laboratories requiring electronic recordkeeping, the SD2-100 supports optional RS-232 serial output (via accessory cable) to log timestamped operational data—including actual temperature, speed, and runtime—to external LIMS or ELN systems. When integrated into regulated environments, this interface may be validated to meet FDA 21 CFR Part 11 requirements for electronic signatures and audit trails, contingent upon site-specific validation protocols and IT infrastructure controls.
Applications
- Pre-analytical preparation of plasma, serum, and whole blood samples prior to centrifugation or immunoassay
- Reconstitution and dispersion of lyophilized proteins and peptides at controlled low temperatures
- Homogenization of bacterial cultures and yeast suspensions during cold lysis protocols
- Stabilization of RNA extraction buffers and DNase/RNase inhibitor cocktails
- QC mixing of calibration standards and reference materials in environmental and food safety testing labs
- Continuous agitation of antibody-conjugated magnetic beads during incubation in automated immunoassay workflows
FAQ
Does the SD2-100 include a heating function?
No. This configuration is strictly refrigerated-only. The heating module is omitted by design and cannot be retrofitted without hardware modification.
What is the lowest achievable temperature?
The instrument achieves a minimum setpoint of 4 °C under standard lab conditions (25 °C ambient, ≤60% RH). Performance below 4 °C is not specified or guaranteed.
Can it cool samples pre-loaded at room temperature?
Yes. Typical cooldown time from 25 °C to 4 °C is approximately 12–18 minutes for a full load of 1.5 mL tubes, depending on thermal mass and ambient conditions.
Is calibration documentation provided with shipment?
Each unit ships with a factory calibration certificate referencing NIST-traceable standards, including temperature and speed verification points at 4 °C, 15 °C, and 30 °C.
Are replacement parts and service support available internationally?
Titan provides global spare parts distribution through authorized regional partners. Technical documentation, firmware updates, and remote diagnostics support are accessible via secure portal with valid product registration.
