HsiangTai CN-1040 Benchtop Centrifuge

Overview

The HsiangTai CN-1040 Benchtop Centrifuge is a compact, brushless DC motor–driven laboratory centrifuge engineered for routine separation tasks in research, clinical, and quality control laboratories. Designed according to fundamental principles of sedimentation kinetics, it delivers consistent radial acceleration to accelerate phase separation of heterogeneous liquid samples—such as blood, cell suspensions, precipitates, and colloidal dispersions—based on particle density, size, and medium viscosity. Its fixed-angle rotor configuration enables rapid pelleting of microcentrifuge tubes and standard conical tubes without requiring complex rotor exchange protocols. With a maximum rotational speed of 5000 rpm and a corresponding relative centrifugal force (RCF) of 3250 × g, the CN-1040 operates within the low-to-mid speed range suitable for general-purpose applications including serum/plasma separation, microbial pellet recovery, and buffer exchange—without demanding ultra-high vacuum or refrigeration infrastructure.

Key Features

• Brushless DC motor ensuring long service life, minimal maintenance, and stable speed regulation under variable load conditions
• ABS polymer housing with integrated transparent polycarbonate viewing window for real-time process monitoring and enhanced operator safety
• Analog speed indicator with calibrated pointer scale for intuitive, non-digital speed verification—compatible with environments where electromagnetic interference (EMI) may affect digital displays
• Programmable 30-minute mechanical timer with automatic shutdown and audible end-of-run signal
• Integrated safety architecture: automatic lid interlock prevents operation when open; instantaneous power-loss braking halts rotation within seconds; dynamic imbalance sensing triggers immediate deceleration if rotor load asymmetry exceeds tolerance thresholds
• Soft-start and soft-stop ramp profiles reduce mechanical stress on both rotor assembly and sample integrity—critical for fragile biological aggregates or temperature-sensitive reagents
• Self-balancing design accommodates minor tube mass variations (±0.1 g per position) without manual counterbalancing

Sample Compatibility & Compliance

The CN-1040 supports standard conical-bottom centrifuge tubes up to 50 mL volume across multiple rotor configurations—including 15 mL × 8, 15 mL × 12, and 50 mL × 4 or × 6 arrangements—enabling flexible throughput scaling for small-batch processing. All rotors are precision-machined from high-strength aluminum alloy and certified for repeated autoclaving (121 °C, 20 min). The unit complies with IEC 61010-1:2010 for electrical safety in laboratory equipment and meets EN 61326-1:2013 electromagnetic compatibility requirements. While not a regulated medical device, its operational consistency aligns with GLP documentation practices for non-clinical laboratory studies, and its mechanical timer output provides traceable run-duration records suitable for internal SOP adherence.

Software & Data Management

As a manually operated benchtop instrument, the CN-1040 does not incorporate embedded software or digital data logging. However, its analog interface and deterministic mechanical timer ensure full auditability in regulated settings where electronic record systems are restricted or require validation. Users may integrate run parameters (speed, time, rotor type) into paper-based or LIMS-managed logbooks using standardized entry templates. For laboratories implementing 21 CFR Part 11–compliant workflows, external USB-connected tachometers or video-based speed verification tools can be deployed during qualification (IQ/OQ) to document performance against manufacturer specifications.

Applications

• Routine serum and plasma separation from whole blood specimens in clinical diagnostics labs
• Pelleting of bacterial and yeast cultures prior to DNA/RNA extraction or protein expression analysis
• Clarification of cell lysates and crude enzyme preparations in biochemistry workflows
• Recovery of precipitated proteins or nucleic acids following ammonium sulfate or ethanol precipitation steps
• Concentration of nanoparticles, liposomes, or extracellular vesicles in nanomedicine development
• Preparative centrifugation in teaching laboratories where robustness, simplicity, and cost-effectiveness are prioritized over programmability

FAQ

Is the CN-1040 refrigerated?
No. It is a ventilated ambient-temperature centrifuge and does not include active cooling.
Can I use this centrifuge for blood bank applications?
Yes—provided centrifugation protocols follow institutional SOPs for hematocrit or platelet-rich plasma preparation at ≤3250 × g.
What rotor options are available for the CN-1040?
Standard configurations include CA-1508 (15 mL × 8), CA-1512 (15 mL × 12), and CA-5004 (50 mL × 4); CA-5006 (50 mL × 6) is also compatible.
Does the unit support rotor certification documentation?
Yes—each rotor is supplied with a factory-issued calibration certificate indicating maximum rated speed and RCF values per ISO 15197:2013 Annex C guidelines.
How often should preventive maintenance be performed?
We recommend biannual visual inspection of rotor threads, lid latch mechanism, and motor ventilation grilles; no scheduled lubrication is required due to brushless motor design.
