Overview
The Titan Timi-12k is a compact, palm-sized high-speed microcentrifuge engineered for rapid, reliable sample separation in resource-constrained or space-limited laboratory environments. Designed around a brushless DC motor and precision-machined aluminum rotor assembly, it delivers stable rotational dynamics at speeds up to 12,000 rpm with a maximum relative centrifugal force (RCF) of 8,550 × g. Its operational principle relies on radial acceleration-induced sedimentation—enabling efficient pelleting of cellular components, precipitated nucleic acids, protein aggregates, and small-volume particulate suspensions. Unlike floor-standing or benchtop centrifuges, the Timi-12k eliminates the need for dedicated bench space or external cooling systems, making it ideal for use inside biosafety cabinets, cold rooms, or mobile diagnostic units where footprint and power efficiency are critical constraints.
Key Features
- Compact footprint (155 × 168 × 118 mm) optimized for placement on crowded workbenches or within laminar flow hoods.
- Brushless DC motor ensures low noise (<55 dB(A)), extended service life, and minimal heat generation during continuous operation.
- Fixed-angle rotor accommodates standard 0.2–2.0 mL microtubes and up to eight 1.5/2.0 mL tubes simultaneously (max. 16 mL total capacity).
- Digital speed control with ±50 rpm accuracy and real-time rpm/RCF dual-display interface for method reproducibility.
- Automatic rotor identification is not implemented; however, rotor geometry is factory-calibrated for Timi-12k-specific angular configuration (12° tilt), ensuring consistent RCF calculation across all operating speeds.
- Soft-braking deceleration profile minimizes resuspension of sensitive pellets, particularly beneficial for RNA isolation and antibody purification workflows.
Sample Compatibility & Compliance
The Timi-12k supports common polypropylene and polyethylene microcentrifuge tubes compliant with ISO 7218 and ASTM D4169 standards for tube integrity under centrifugal stress. It is routinely validated for use with commercially available spin-column kits (e.g., silica-membrane-based DNA/RNA purification systems) and low-volume protein precipitation protocols. While not certified for clinical diagnostics under FDA 21 CFR Part 820 or IVD Directive 98/79/EC, its mechanical design adheres to IEC 61010-1:2010 safety requirements for electrical equipment used in laboratory environments. Routine maintenance—including rotor inspection per manufacturer-recommended intervals (every 500 hours or annually)—supports long-term compliance with GLP documentation practices.
Software & Data Management
The Timi-12k operates as a standalone instrument without embedded software or network connectivity. All parameter inputs (time, speed) are managed via tactile push-button controls with LED feedback. No data logging, audit trail, or electronic record functionality is provided—consistent with its classification as a Class I general-purpose laboratory device under ISO/IEC 17025 Annex A.3. For laboratories requiring traceability, users may integrate the Timi-12k into broader digital lab workflows via external timers, barcode-scanned protocol sheets, or LIMS-linked SOP documentation referencing fixed operational parameters (e.g., “Timi-12k @ 12,000 rpm, 30 sec, 4 °C”).
Applications
- Routine pelleting of PCR products, plasmid preps, and column-eluted nucleic acids prior to ethanol precipitation or downstream enzymatic reactions.
- Clarification of bacterial lysates and mammalian cell supernatants in early-stage bioprocessing development.
- Micro-volume solvent extraction steps in environmental sample preparation (e.g., pesticide residue analysis in water extracts).
- Point-of-need centrifugation in field-deployable molecular testing platforms, including isothermal amplification assays requiring rapid spin-down before lateral flow detection.
- Teaching laboratories conducting foundational centrifugation experiments where cost, safety, and ease of operation outweigh advanced programmability requirements.
FAQ
Is the Timi-12k suitable for use with sealed PCR tubes?
Yes—its rotor design accommodates capped 0.2 mL strip tubes and individual 1.5/2.0 mL tubes rated for ≥12,000 rpm per manufacturer specifications.
Does it include temperature control?
No—the Timi-12k is a non-refrigerated microcentrifuge. Ambient operation is recommended; for temperature-sensitive applications, pre-chill samples and rotor prior to run.
Can it be operated continuously for extended durations?
Continuous operation is limited to ≤15 minutes per cycle to maintain thermal stability of the motor and electronics; allow ≥5 minutes cooldown between cycles.
What safety certifications does it carry?
It complies with IEC 61010-1:2010 for laboratory electrical safety and carries CE marking for EMC and Low Voltage Directive conformity.
Is rotor balancing required before each run?
Yes—symmetrical loading of opposing tube positions is mandatory. The rotor does not support single-tube operation; minimum load is two tubes placed diametrically opposite.
