Overview
The Shanghai Anting DL-5C Automatic Lid-Release Benchtop Centrifuge is a refrigerated, low-speed centrifugal separation system engineered for routine sample processing in clinical laboratories, quality control environments, and academic research settings. It operates on the principle of sedimentation under controlled gravitational force (RCF), enabling efficient separation of suspended particles—such as cells, organelles, precipitates, or immiscible liquid phases—based on density differentials. Designed specifically for applications requiring gentle yet reproducible pelleting without thermal degradation, the DL-5C integrates active refrigeration to maintain sample integrity during extended runs. Its swing-bucket horizontal rotor configuration ensures uniform sedimentation across all tubes and minimizes shear stress on delicate biological specimens. The automatic lid-release mechanism enhances workflow efficiency and operator safety by preventing premature opening during deceleration or residual rotation.
Key Features
- Refrigerated operation with precise temperature control (typically 0–4°C range, ambient-dependent) to preserve thermolabile samples including plasma, serum, whole blood, and cell suspensions.
- Electronic lid lock system compliant with IEC 61010-2-020 safety standards, ensuring mechanical interlock engagement until rotational speed drops below safe threshold (≤100 rpm).
- Swing-bucket horizontal rotor (No. 1 configuration) accommodating up to 56 × 5 mL tubes at maximum rated speed (4000 rpm), delivering consistent RCF distribution and optimal pellet formation.
- Digital timer with adjustable range from 0 to 99 minutes, supporting both timed and continuous operation modes.
- High-strength engineering plastic housing offering corrosion resistance, vibration damping, and reduced mass—facilitating stable placement on standard laboratory benches without anchoring.
- Brushless DC motor providing high torque at low speeds, low acoustic noise (<65 dB(A)), and extended service life with minimal maintenance requirements.
Sample Compatibility & Compliance
The DL-5C supports common laboratory tube formats including polypropylene (PP) and polycarbonate (PC) conical-bottom centrifuge tubes (5 mL capacity), compatible with standard rack-based loading protocols. It meets essential electrical safety and electromagnetic compatibility (EMC) requirements per GB 4793.1–2007 (Chinese national equivalent of IEC 61010-1). While not certified to ISO 13485 or FDA 21 CFR Part 11 out-of-the-box, its electronic timer, lid-lock logic, and non-volatile run history (where implemented in firmware variants) support GLP-aligned documentation practices. Users performing regulated testing (e.g., clinical diagnostics per CLIA or ISO 15189) are advised to validate performance against local SOPs and conduct periodic calibration per manufacturer-recommended intervals.
Software & Data Management
The DL-5C operates via an embedded microcontroller interface with LED display and tactile push-button controls—no external PC connection or proprietary software required. All operational parameters (speed, time, temperature if equipped) are retained in volatile memory during power cycling; however, it does not feature audit-trail logging, user-access levels, or exportable run records. For laboratories requiring traceability, integration into LIMS or ELN systems must be achieved through manual entry or third-party hardware interfaces (e.g., RS-232 or analog signal output modules, where available as optional accessories). Firmware updates are performed exclusively by authorized service technicians using dedicated diagnostic tools.
Applications
- Routine blood component separation (serum/plasma isolation from whole blood in clinical labs).
- Precipitation recovery in protein purification workflows prior to column chromatography.
- Sedimentation of microbial cultures or yeast cells for downstream RNA/DNA extraction.
- Clarification of crude extracts in natural product screening or food safety analysis.
- Phase separation in emulsion stability studies and colloidal formulation development.
- Preparative centrifugation of particulates in environmental water or soil suspension analysis.
FAQ
Is the DL-5C suitable for centrifuging infectious or biohazardous samples?
Yes—when used with sealed, screw-cap conical tubes and operated inside a certified biosafety cabinet or secondary containment, provided rotor integrity and lid seal are verified before each run.
Does the unit include rotor balancing detection?
No—the DL-5C lacks automatic imbalance sensing; users must manually balance loads to within ±0.1 g per opposing position to prevent excessive vibration or shutdown.
Can the centrifuge operate without refrigeration?
Yes—the cooling system may be disabled via front-panel setting; however, prolonged runs above ambient temperature may compromise heat-sensitive samples.
What maintenance is required for long-term reliability?
Biannual inspection of rotor threads, lid gasket integrity, and motor brushless commutation status; annual recalibration of speed and timer accuracy using NIST-traceable tachometer and stopwatch.
Is rotor autoclaving supported?
No—rotors are constructed from aluminum alloy with anodized finish and are not designed for steam sterilization; wipe-down with 70% ethanol or approved disinfectants is recommended.
