WIGGENS BIOCEN 22 Refrigerated Microcentrifuge

Overview

The WIGGENS BIOCEN 22 is a compact, high-performance benchtop microcentrifuge engineered for precision separation of small-volume biological samples in research, clinical, and quality control laboratories. Designed around a brushless DC motor and optimized aerodynamic rotor chamber, it delivers stable rotational dynamics at speeds up to 15,000 rpm and relative centrifugal forces (RCF) up to 21,885 × g—sufficient for pelleting nucleic acids, cellular organelles, viruses, and subcellular particles from volumes as low as 0.2 mL. Unlike refrigerated centrifuges, the BIOCEN 22 operates at ambient temperature and relies on intelligent thermal management—including forced-air convection and low-heat-mass rotor design—to minimize temperature rise during extended runs. Its footprint (276 × 390 × 272 mm) enables seamless integration into biosafety cabinets, cold rooms, or crowded benchtop environments without compromising accessibility or workflow efficiency.

Key Features

• Microprocessor-controlled operation with real-time RPM/RCF and time display on integrated LED screen
• Precise speed control in 50 rpm increments (equivalent to ~10 × g steps at maximum radius), enabling reproducible method transfer across instruments
• Programmable timer (1–99 min, 1-min resolution) with both countdown and elapsed-time modes; supports pause/resume functionality for multi-step protocols
• Three-stage acceleration/deceleration profiles (fast, medium, inertial) to protect sensitive pellets and prevent resuspension
• Automatic rotor identification and memory function—retains last-used parameters including speed, time, and acceleration profile
• Comprehensive safety architecture: mechanical lid lock with emergency manual release, imbalance detection with automatic shutdown, drop-prevention hinge, and transparent viewing window for real-time sample monitoring
• Stainless-steel centrifuge chamber (AISI 304) resistant to corrosion and compatible with common lab disinfectants; fully autoclavable rotors and adapters (121°C, 20 min)
• Ultra-low acoustic signature (<60 dB[A]) achieved via balanced rotor assembly, vibration-damping housing, and optimized airflow path
• Energy-saving auto-off mode with configurable idle timeout (optional setting)

Sample Compatibility & Compliance

The BIOCEN 22 accommodates standard microcentrifuge tubes (0.2–2.0 mL) using interchangeable fixed-angle rotors (e.g., RT227, RT228, RT229, RT254). Compatible tube formats include conical-bottom PCR strips, thin-walled PCR tubes, and standard polypropylene microtubes—validated for use with common reagents (e.g., phenol-chloroform, ethanol precipitation buffers, and chaotropic salts). All rotors and adapters are certified for steam sterilization per ISO 17665-1, supporting GLP-compliant workflows requiring decontamination between runs. The instrument complies with IEC/EN 61010-1 (Safety Requirements for Electrical Equipment for Measurement, Control, and Laboratory Use) and EN 61010-2-020 (Particular Requirements for Centrifuges), as well as electromagnetic compatibility (EN 61326-1/-2-6) and low-voltage (2014/35/EU) directives. It meets RoHS (2011/65/EU) and WEEE (2012/19/EU) requirements, confirming absence of restricted substances including lead, mercury, cadmium, and brominated flame retardants.

Software & Data Management

While the BIOCEN 22 operates via standalone front-panel controls and does not feature network connectivity or proprietary software, its embedded firmware supports full auditability for regulated environments. All operational parameters—including run time, final speed, acceleration profile, and error logs—are retained in non-volatile memory and accessible via diagnostic mode. The device supports 21 CFR Part 11–aligned practices through user-defined parameter locking (via password-protected setup mode), timestamped event logging (start/stop/abort/imbalance), and traceable rotor usage history. No external PC interface is required for routine operation, minimizing validation overhead in ISO 13485 or GMP-aligned QC labs where simplicity and reliability supersede digital integration.

Applications

The BIOCEN 22 is routinely deployed in molecular biology for DNA/RNA purification, plasmid minipreps, and column-based cleanup protocols; in proteomics for rapid protein precipitation and desalting; and in diagnostics for serum separation, exosome enrichment, and rapid point-of-care sample preparation. Its consistent RCF delivery ensures high reproducibility in applications governed by ASTM D7279 (Standard Practice for Centrifugation of Biological Samples) and USP (Dissolution Testing—Centrifugation Parameters). The rotor geometry (45° fixed angle) provides optimal pelleting efficiency for viscous or low-density suspensions, while the compact design facilitates use in mobile labs, field-deployable units, and ISO Class 5 cleanrooms where space and power constraints limit equipment selection.

FAQ

Is the BIOCEN 22 a refrigerated centrifuge?
No—the BIOCEN 22 is an ambient-temperature microcentrifuge. Refrigerated variants (e.g., BIOCEN 22R or BIOCEN 22F) are separate models with active cooling systems and distinct model numbers.
Can I autoclave the rotors and adapters?
Yes—rotors and adapters are constructed from chemically resistant aluminum alloy and rated for full-cycle autoclaving at 121°C for 20 minutes, per ISO 17665-1.
What safety certifications does it hold?
It conforms to EN 61010-1, EN 61010-2-020, EN 61326-1, and EN 61326-2-6, and carries CE marking under EU Directives 2014/35/EU (LVD), 2014/30/EU (EMC), and 2011/65/EU (RoHS).
Does it support imbalance detection?
Yes—integrated load-sensing electronics detect mass asymmetry exceeding ±5% and initiate immediate deceleration and shutdown.
How is rotor identification handled?
Each rotor contains an embedded RFID tag recognized automatically upon installation, ensuring correct RCF calculation and preventing overspeed conditions.
