Centurion Scientific C2004 Benchtop Centrifuge

Overview

The Centurion Scientific C2004 is a robust, CE-marked benchtop centrifuge engineered for routine separation tasks in clinical diagnostics, microbiology, cell culture, and general laboratory workflows. It operates on the principle of sedimentation under controlled centrifugal force—generating radial acceleration to separate components based on density, size, and shape within heterogeneous suspensions. Designed for reliability in high-throughput environments, the C2004 delivers consistent performance at speeds up to 4000 rpm and relative centrifugal forces (RCF) up to 2200 × g—sufficient for pelleting bacteria, mammalian cells, and subcellular organelles without compromising sample integrity. Its compact footprint (27 × 32 × 47 cm) and low acoustic signature (<60 dB[A]) make it suitable for shared lab spaces, biosafety cabinets, or quality control laboratories where operational noise and spatial constraints are critical considerations.

Key Features

• European-sourced brushless DC motor ensuring long service life, minimal maintenance, and precise speed regulation across the full 500–4000 rpm range
• Stainless-steel centrifuge chamber with smooth, crevice-free interior surfaces for rapid decontamination and compliance with ISO 13485 cleanroom-compatible cleaning protocols
• Four-point lid locking mechanism with integrated lid position sensor—prevents operation unless fully engaged and automatically halts rotation if opened mid-run
• Dual-mode display: simultaneous or selectable readout of rotational speed (rpm) and relative centrifugal force (×g), supporting method transfer between instruments using either unit convention
• Ten programmable run profiles with independent acceleration/deceleration ramp settings (10 selectable levels), enabling optimization for shear-sensitive samples such as peripheral blood mononuclear cells (PBMCs) or exosome preparations
• Pulse mode (1–90 s) for brief, controlled mixing prior to full-speed runs—ideal for resuspending pellets or homogenizing viscous reagents
• Integrated safety systems: real-time imbalance detection with auto-recovery reset, overspeed monitoring via optical tachometer, and thermal cut-off for motor protection
• High-strength steel-alloy chassis providing mechanical stability during extended operation and resistance to vibration-induced drift

Sample Compatibility & Compliance

The C2004 supports standard laboratory tube formats—including polypropylene and polycarbonate conical tubes (15 mL, 50 mL), glass centrifuge tubes, and sealed PCR strip carriers—when used with validated rotors. Compatible rotor options include the BRK5324 (24 × 15 mL angle rotor), BRK5308 (8 × 50 mL angle rotor), and BRK1000 (4 × 100 mL horizontal rotor), all rated for maximum operation at 4000 rpm / 2200 × g. Each rotor undergoes individual dynamic balancing and is certified to EN 61000-6-2 (immunity) and EN 61000-6-3 (emissions). The instrument complies with IEC 61010-1:2010 for laboratory electrical equipment safety and meets essential requirements for in vitro diagnostic (IVD) use under EU Regulation 2017/746 when operated within defined parameters and maintained per manufacturer-recommended intervals.

Software & Data Management

While the C2004 operates via an embedded microcontroller without external PC connectivity, its firmware architecture supports full audit trail functionality required under GLP and GMP environments. All parameter changes—including speed, time, acceleration/deceleration ramps, and program recalls—are timestamped and stored in non-volatile memory. The system retains the last ten executed protocols along with start/stop timestamps and any triggered safety events (e.g., lid interlock breach, imbalance alert). Optional data logging modules (sold separately) enable RS-232 or USB-to-serial export of session logs compliant with FDA 21 CFR Part 11 requirements when paired with validated third-party LIMS integration software.

Applications

• Routine pelleting of bacterial cultures (E. coli, Bacillus spp.) and yeast cells from liquid media
• Separation of whole blood into plasma, buffy coat, and erythrocyte fractions for downstream ELISA or flow cytometry
• Clarification of cell lysates prior to protein purification or nucleic acid extraction
• Preparative isolation of mitochondria and nuclei from tissue homogenates using differential centrifugation protocols
• Concentration of viral particles or extracellular vesicles from conditioned cell culture supernatants
• Quality control testing of reagent stability, including emulsion phase separation and particle settling kinetics

FAQ

Is the C2004 suitable for biosafety level 2 (BSL-2) applications?
Yes—the stainless-steel chamber and sealed rotor interface minimize aerosol generation; when used with capped tubes and appropriate biosafety-certified rotors, it meets CDC/NIH BSL-2 containment recommendations.
Can I validate centrifugation methods on this instrument for regulatory submissions?
Absolutely—the device’s ±1 rpm repeatability, traceable speed calibration, and event-logged operational history support IQ/OQ/PQ documentation aligned with ISO/IEC 17025 and ASTM E2500-13 guidelines.
Does the C2004 support continuous operation beyond 99 minutes?
No—the timer is fixed at 0–99 minutes; however, sequential programs can be manually chained to achieve extended runs without interruption.
Are rotor certifications included with purchase?
Each rotor ships with a unique serial-numbered certificate of conformity, listing maximum speed, RCF, and material composition per ISO 15523-1:2021 standards.
What maintenance is required to retain warranty coverage?
Annual verification of speed accuracy and imbalance threshold calibration by an authorized Centurion Scientific service technician is mandatory; user-performed cleaning and visual inspection logs must be retained for audit purposes.
