Titan Timi-2S Dual-Speed Micro Centrifuge

Overview

The Titan Timi-2S Dual-Speed Micro Centrifuge is a compact, benchtop-ready centrifugation solution engineered for rapid, reliable separation of small-volume biological and chemical samples in resource-constrained or high-throughput laboratory environments. Utilizing fixed-angle rotor geometry and direct-drive brushless DC motor technology, the Timi-2S delivers precise, repeatable acceleration and deceleration profiles at two preset rotational speeds—4000 rpm and 7000 rpm—enabling users to select optimal conditions for pelleting nucleic acids, precipitating proteins, clarifying cell lysates, or concentrating microvolume reagents without requiring programmable speed control. Its mechanical design adheres to ISO 13485-aligned manufacturing practices and incorporates passive thermal management to maintain ambient operating temperatures during extended use, minimizing sample warming—a critical factor in preserving enzyme activity and RNA integrity.

Key Features

• Dual-speed operation with tactile push-button selection (4000 rpm / 7000 rpm), eliminating menu navigation delays and reducing operator error in time-sensitive workflows.
• Fixed-angle aluminum rotor accommodating up to 16 × 0.2–2.0 mL microcentrifuge tubes (2 × 8-position configuration), optimized for uniform radial force distribution and rapid sedimentation kinetics.
• High-efficiency brushless DC motor ensures low vibration, extended service life (>10,000 hr MTBF), and compliance with IEC 61000-6-3 electromagnetic compatibility standards.
• Integrated safety interlock system prevents lid opening during rotation and automatically halts operation if imbalance exceeds 5% mass asymmetry across opposing tube positions.
• Compact footprint (155 × 168 × 118 mm) and lightweight construction (≤1.8 kg) enable placement on crowded biosafety cabinets, cold room benches, or mobile lab carts without structural reinforcement.
• Non-slip silicone base and beveled edge design provide stable operation on inclined or polished surfaces, meeting ASTM D4941-15 static friction requirements for laboratory equipment.

Sample Compatibility & Compliance

The Timi-2S supports standard polypropylene and polyethylene microcentrifuge tubes (0.2 mL PCR strips, 0.5 mL, 1.5 mL, and 2.0 mL formats), including certified RNase/DNase-free variants. It is validated for use with common aqueous buffers (PBS, Tris-HCl, TE), ethanol/isopropanol precipitations, and low-viscosity organic solvents (e.g., chloroform in phenol-chloroform extractions). While not designed for clinical diagnostic use under CLIA or IVD regulations, its mechanical performance aligns with general-purpose laboratory requirements defined in ISO/IEC 17025:2017 Annex A.2 for equipment verification, and routine operation satisfies GLP documentation prerequisites for raw data traceability when paired with laboratory notebooks or LIMS-integrated log entries.

Software & Data Management

As a non-programmable, hardware-controlled instrument, the Timi-2S does not incorporate embedded firmware, touchscreen interfaces, or digital connectivity (USB/Ethernet/Wi-Fi). This architecture eliminates cybersecurity vulnerabilities, reduces calibration drift from software aging, and ensures deterministic response timing—critical for SOP-driven QC/QA labs operating under FDA 21 CFR Part 11 Annex 11 principles where audit trails must reflect physical actuation only. Operational parameters are recorded manually or via external timestamped logbooks; no electronic records are generated, thereby simplifying compliance validation for regulated environments where ALCOA+ data integrity criteria apply strictly to instrument-generated outputs.

Applications

• Routine microscale pelleting in molecular biology workflows—including plasmid minipreps, spin-column binding/elution steps, and post-PCR cleanup.
• Cell fractionation support: rapid removal of cellular debris prior to Western blot sample preparation or ELISA plate coating.
• Point-of-use concentration of dilute antibody solutions, fluorescent dyes, or synthetic oligonucleotides in core facilities and teaching labs.
• Field-deployable centrifugation in mobile diagnostics units or environmental sampling vans where power efficiency (<12 W idle, <35 W peak) and mechanical robustness are prioritized over variable speed control.
• Quality control screening in pharmaceutical excipient manufacturing, supporting USP dissolution testing sample clarification protocols.

FAQ

Is the Timi-2S suitable for centrifuging blood samples?
No—it is not rated for biohazard containment or aerosol suppression. Blood processing requires sealed rotors, biosafety certification (e.g., IEC 61010-2-020), and validated decontamination cycles.
Can I use 0.5 mL tubes in the Timi-2S rotor?
Yes—the rotor accepts all standard conical-bottom microcentrifuge tubes ranging from 0.2 mL to 2.0 mL, provided tube height does not exceed 46 mm.
Does the unit include a rotor locking mechanism?
Yes—a spring-loaded cam latch secures the rotor assembly during operation and requires deliberate downward pressure to release, preventing accidental disengagement.
What is the expected service interval for maintenance?
Under normal usage (≤4 hrs/day, ambient temperature ≤30°C), no scheduled maintenance is required; annual visual inspection of rotor threads and lid seal integrity is recommended per ISO/IEC 17025 Clause 6.4.8.
Is CE marking applicable to this device?
The Timi-2S complies with the essential health and safety requirements of the EU Machinery Directive 2006/42/EC and carries CE marking for export to EEA markets; full Declaration of Conformity is available upon request.
