Overview
The Ortoalresa Dilitcen 22 is a high-capacity benchtop centrifuge engineered for reproducible, high-throughput separation in clinical diagnostics, biotechnology, and academic research laboratories. Designed and manufactured in Spain with over three decades of centrifugation expertise, it operates on the principle of sedimentation under controlled rotational force—applying precise radial acceleration to separate particles based on size, density, and shape. With a maximum capacity of 4 × 1000 mL and a rated speed of 14,300 rpm (21,948 × g), the Dilitcen 22 bridges the functional gap between standard benchtop units and floor-standing preparative systems—delivering large-volume processing without compromising footprint or operational safety. Its robust stainless-steel chamber, integrated thermal management, and microprocessor-controlled drive system ensure consistent performance across extended run cycles, particularly for applications requiring high sample integrity—such as plasma fractionation, cell pellet harvesting, and viral particle concentration.
Key Features
- Full-color TFT touchscreen interface visible from ≥3 meters, displaying real-time RPM, RCF, elapsed time, programmable acceleration/deceleration profiles (PCBS), and Unbalance Location System (ULS) feedback.
- Stepwise parameter control in increments of 10 rpm or 10 × g; dual-countdown timer (from setpoint or from zero) with 1-second resolution and programmable duration from 1 minute to 99 hours.
- 175 selectable acceleration/deceleration ramps via PCBS to minimize post-centrifugation resuspension—critical for delicate biological pellets and macromolecular fractions.
- ULS detects and graphically identifies the angular position of unbalanced tubes on-screen, enabling rapid correction prior to rotor engagement.
- 40 user-programmable protocols stored under password protection; automatic rotor recognition and memory retention of last-used parameters including speed, time, and brake profile.
- Brushless induction motor with zero-maintenance operation; automatic lid locking with dual electromechanical interlocks, emergency manual release, and drop-protection mechanism.
- Noise emission <60 dB(A) during operation; forced-air cooling maintains chamber temperature stability; auto-shutdown after 8 hours of inactivity (configurable).
Sample Compatibility & Compliance
The Dilitcen 22 accommodates standard laboratory consumables including conical tubes (5 mL, 10 mL, 15 mL, 50 mL), microplates (96-well, deep-well), and custom adapters—enabling seamless integration into routine workflows for blood banking, bioprocessing, and nucleic acid purification. All rotors and adapters are autoclavable (121°C, 20 min), supporting GLP-compliant cleaning validation. The centrifuge complies with IEC/EN safety standards for laboratory equipment (EN 61010-1, EN 61010-2-020) and electromagnetic compatibility (EN 61326-1, EN 61326-2-6). It meets essential requirements of EU Directives covering RoHS (2011/65/EU), WEEE (2012/19/EU), EMC (2014/30/EU), Low Voltage (2014/35/EU), and In Vitro Diagnostic Medical Devices (98/79/EC)—ensuring suitability for regulated environments including ISO 13485-certified facilities.
Software & Data Management
Equipped with native RS-232 and USB interfaces, the Dilitcen 22 supports bidirectional communication with laboratory information management systems (LIMS) and PC-based configuration tools. All run logs—including timestamped start/stop events, actual RCF achieved, rotor ID, imbalance alerts, and error codes—are stored locally and exportable in CSV format. Audit-trail functionality records operator login, protocol modification history, and parameter overrides—supporting compliance with FDA 21 CFR Part 11 requirements when deployed with validated software extensions. Firmware updates are delivered via secure USB import, maintaining traceability and version control.
Applications
- Clinical laboratories: Whole blood separation into serum/plasma, PBMC isolation, urine sediment analysis.
- Biotechnology: Harvesting mammalian and microbial cells, clarifying lysates, concentrating extracellular vesicles and recombinant proteins.
- Research settings: Preparative isolation of organelles (mitochondria, nuclei), subcellular fractionation, and high-yield nucleic acid recovery from large-volume samples.
- Quality control: Stability testing of suspensions and emulsions per USP light scattering methodology.
FAQ
Is the Dilitcen 22 suitable for biosafety level 2 (BSL-2) applications?
Yes—the sealed stainless-steel chamber, autoclavable rotors, and lid interlock system meet containment requirements for BSL-2 work when used with appropriate tube caps and secondary containment.
Can I use non-Ortoalresa rotors with this centrifuge?
No—automatic rotor recognition requires certified Ortoalresa rotors with embedded identification chips to prevent overspeed conditions and enforce safety limits.
Does the device support remote monitoring or network integration?
Standard RS-232/USB enables local PC connection; optional Ethernet gateway modules (sold separately) provide SNMP-compatible status reporting and event logging for centralized lab infrastructure.
What is the warranty coverage and service support structure?
Ortoalresa provides a 24-month limited warranty on parts and labor; field service engineers are available across EMEA and APAC regions, with technical documentation compliant with ISO/IEC 17025 calibration traceability requirements.
