Ortoalresa Digicen 22 Benchtop Centrifuge

Overview

The Ortoalresa Digicen 22 is a high-performance benchtop centrifuge engineered for precision, reproducibility, and operational safety in routine and advanced laboratory workflows. Designed and manufactured in Spain with over three decades of centrifugation expertise, this instrument employs fixed-angle rotor architecture optimized for rapid sedimentation of biological macromolecules—including proteins, nucleic acids, subcellular organelles, and viral particles—under controlled gravitational forces up to 26,480 × g. Its microprocessor-controlled induction motor delivers consistent torque across the full speed range (100–16,500 rpm), eliminating brush wear and minimizing maintenance requirements. The Digicen 22 operates within Class II biosafety-compatible environments and supports GLP-compliant documentation protocols through programmable run logging and parameter retention.

Key Features

• Intelligent Drive System: Brushless induction motor ensures stable rotational performance, low thermal drift, and extended service life without carbon brush replacement or commutator servicing.
• Programmable Ramp Control (PCBS): 175 selectable acceleration/deceleration profiles prevent post-centrifugation resuspension of pellets; enables gentle pelleting of sensitive biomolecules or rapid spin-down for high-throughput sample preparation.
• Multi-Parameter Display & Interface: Backlit LCD shows real-time RPM, RCF, elapsed time, remaining time, and ramp status. Programmable in 10 rpm / 10 × g increments with ±5 s timer accuracy from 1 s to 99 min.
• Memory & Recall Functionality: 16 user-defined protocols stored in non-volatile memory; last-run parameters retained after power cycle for immediate re-execution.
• Acoustic & Visual Alert System: Audible beeps and on-screen icons indicate lid status, imbalance detection, rotor recognition failure, or end-of-run completion.
• Low-Noise Operation: Acoustically damped housing and balanced rotor chamber maintain sound pressure levels below 60 dB(A) at 1 m distance—suitable for shared lab spaces and open-plan facilities.

Sample Compatibility & Compliance

The Digicen 22 accommodates a broad spectrum of sample formats via interchangeable fixed-angle rotors, including 4 × 100 mL conical tubes, 28 × 15 mL or 32 × 15 mL round-bottom tubes, and microtiter plates (96-well). Compatible accessories include adapters for 50 mL, 30 mL, 10 mL, and 1.5–2.0 mL microcentrifuge tubes. All rotors and tube adapters are autoclavable (121 °C, 20 min, saturated steam), supporting ISO 13485-aligned sterilization protocols for clinical and diagnostic applications. The stainless-steel centrifuge chamber facilitates rapid decontamination and meets EN 61010-2-101 requirements for protection against biological hazards. Integrated imbalance detection halts operation if mass asymmetry exceeds ±5 g per rotor position, ensuring mechanical integrity and operator safety.

Software & Data Management

While the Digicen 22 operates as a standalone instrument without external PC connectivity, its embedded firmware supports audit-trail-ready operation in regulated environments. All executed runs log timestamp, selected rotor ID, speed, RCF, duration, and ramp profile to internal memory—accessible via menu navigation for verification during GLP/GMP audits. The device complies with IEC 62304 software lifecycle standards for Class B medical devices under IVDD 98/79/EC. Firmware updates are performed via secure USB interface (optional accessory), maintaining traceability per FDA 21 CFR Part 11 electronic record requirements when paired with validated laboratory information management systems (LIMS).

Applications

• Purification of plasmid DNA, genomic DNA, and RNA from bacterial lysates and mammalian cell cultures
• Clarification of crude protein extracts prior to chromatography or electrophoresis
• Isolation of mitochondria, nuclei, and membrane vesicles using differential centrifugation protocols
• Routine serum/plasma separation in clinical chemistry and immunoassay workflows
• Concentration of virus particles and exosomes for downstream characterization
• Preparative centrifugation of nanoparticles and colloidal suspensions in materials science labs

FAQ

Does the Digicen 22 support refrigerated operation?
No—the Digicen 22 is a non-refrigerated benchtop model. For temperature-sensitive applications requiring 4 °C stabilization, Ortoalresa offers the Digicen 22R variant with Peltier-based cooling.
Can I use third-party rotors with this centrifuge?
Only Ortoalresa-certified rotors are recognized by the automatic rotor identification system. Unauthorized rotors will trigger an error lockout and prevent operation.
What is the maximum allowable imbalance tolerance?
The built-in imbalance sensor detects deviations exceeding ±5 g per rotor position and initiates immediate deceleration to protect mechanical components and ensure user safety.
Is the centrifuge compliant with FDA 21 CFR Part 11?
Yes—when operated with enabled audit trail logging and paired with a validated LIMS or electronic lab notebook (ELN), the Digicen 22 meets electronic signature and record retention requirements under Part 11.
How often does the device require calibration verification?
Annual speed and timer calibration is recommended per ISO/IEC 17025 guidelines; Ortoalresa provides certified calibration services and traceable certificates upon request.
