Titan Timi-7k Compact Palm-Sized Centrifuge

Overview

The Titan Timi-7k is a compact, palm-sized centrifuge engineered for rapid, reliable micro-volume sample separation in resource-constrained or space-limited laboratory environments. Designed around a brushless DC motor and precision-machined aluminum rotor assembly, it operates on the principle of sedimentation-based separation—applying controlled centrifugal force to accelerate phase separation of suspended particles, cells, or precipitates from liquid matrices. Its fixed-angle rotor geometry ensures consistent trajectory and minimal runout across repeated cycles, supporting high reproducibility in routine benchtop workflows such as PCR tube pelleting, spin-column purification, microfiltration preparation, and small-scale reagent clarification. With a maximum rotational speed of 7000 rpm and a corresponding relative centrifugal force (RCF) of 2910 × g, the Timi-7k delivers sufficient acceleration for low-to-moderate density differentials without requiring refrigeration or complex balancing protocols.

Key Features

• Ultra-compact footprint (55 × 168 × 118 mm) optimized for biosafety cabinets, laminar flow hoods, and mobile lab carts
• Brushless DC motor with soft-start/stop control to minimize sample disturbance and extend service life
• Fixed-angle rotor accommodating up to eight 1.5/2.0 mL microcentrifuge tubes or four 4 mL tubes—compatible with standard polypropylene and polycarbonate centrifuge tubes
• Digital LED display showing real-time speed (rpm), elapsed time, and status indicators (run/pause/error)
• Programmable timer (0–99 minutes) with automatic rotor deceleration and audible end-of-run alert
• Over-speed and imbalance detection circuitry compliant with IEC 61010-1 safety standards for laboratory electrical equipment
• Low acoustic emission (<55 dB(A) at 1 m) suitable for open-plan labs and teaching environments

Sample Compatibility & Compliance

The Timi-7k supports common micro-volume consumables used across molecular biology, clinical diagnostics, and quality control labs—including Eppendorf-style 1.5/2.0 mL tubes, spin columns, and 4 mL round-bottom microtubes. It is not intended for use with hazardous, volatile, or high-viscosity samples exceeding ISO 15195-defined Class B biohazard containment thresholds. The device meets CE marking requirements under Directive 2014/30/EU (EMC) and 2014/35/EU (LVD), and conforms to GB/T 14710–2009 environmental testing standards for domestic laboratory instruments. While not certified for GMP or GLP-regulated production environments, its operational repeatability and traceable timing functionality support documentation practices aligned with ISO/IEC 17025 clause 7.7 (ensuring result validity).

Software & Data Management

The Timi-7k operates as a standalone instrument without proprietary software dependencies. All operational parameters are set via front-panel controls; no USB, Bluetooth, or network interface is provided. However, its programmable timer and consistent RCF output enable integration into documented SOPs where manual log entries (e.g., operator ID, date/time, speed/duration, sample ID) fulfill basic audit-trail requirements per FDA 21 CFR Part 11 Annex A guidance for non-electronic records. For laboratories implementing LIMS or ELN systems, centrifugation events can be manually recorded using standardized metadata fields including “Instrument ID”, “Run Time”, “RCF Applied”, and “Tube Configuration”.

Applications

• Routine pelleting of nucleic acids, proteins, or cellular debris prior to electrophoresis or spectrophotometric analysis
• Spin-down of column-based DNA/RNA extraction kits (e.g., silica-membrane or magnetic bead formats)
• Clarification of bacterial lysates, enzyme reaction mixtures, or antibody supernatants
• Preparation of calibration standards and QC reference materials in analytical chemistry workflows
• Field-deployable sample stabilization in environmental monitoring and point-of-care research settings
• Student training in fundamental centrifugation principles within undergraduate life science curricula

FAQ

Is the Timi-7k suitable for continuous operation?
No—this model is rated for intermittent duty cycles only. Continuous operation beyond 30 minutes requires ≥10-minute cooldown intervals to maintain thermal stability of the motor and electronics.
Can I use this centrifuge with 0.5 mL tubes?
Yes, when used with compatible tube adapters (sold separately); the rotor accepts 0.5 mL tubes only when inserted into designated 1.5 mL tube slots with proper mechanical support.
Does the Timi-7k include a rotor lock mechanism?
Yes—a manual rotor latch prevents accidental lid opening during operation and ensures secure rotor seating before acceleration.
What voltage does the power adapter supply?
The included external AC/DC adapter outputs 12 V DC at 2 A, meeting SELV (Safety Extra-Low Voltage) requirements per IEC 61558-2-16.
Is rotor calibration required prior to first use?
No factory calibration is needed—the rotor is statically balanced during assembly and verified per ISO 1940-1 Grade G6.3 tolerances; users should visually inspect for deformation or corrosion before each use.
