WIGGENS Digtor 21 col Benchtop Centrifuge

Overview

The WIGGENS Digtor 21 col is a high-reliability benchtop centrifuge engineered for routine separation tasks in life science laboratories, clinical sample processing, and aesthetic medicine applications. Designed around fixed-angle rotor architecture, it operates on the principle of sedimentation under controlled gravitational force (RCF), enabling rapid concentration and isolation of cellular components—including adipose-derived stromal vascular fraction (SVF), platelet-rich plasma (PRP), and microvesicles—without thermal degradation or mechanical shear-induced disruption. With a maximum speed of 3000 rpm and an achievable relative centrifugal force of 1801 × g, the Digtor 21 col delivers consistent performance for low-to-moderate density separations such as whole blood fractionation, adipose tissue processing, and organelle pelleting. Its compact footprint and robust stainless-steel chamber meet stringent hygiene and operational safety requirements common in GMP-aligned clinical labs and ISO 13485-certified medical device manufacturing environments.

Key Features

• TFT color display with >3 m viewing distance, showing real-time RPM, RCF, elapsed time, acceleration/deceleration profiles, and rotor imbalance status
• Digital PCBS (Progressive Control Braking System) with 175 selectable acceleration/deceleration ramps to minimize post-centrifugation resuspension and preserve pellet integrity
• ULS (Unbalance Location System): identifies and displays the exact position number of unbalanced rotor bucket(s) prior to operation
• Stepwise speed/RCF control in increments of 10 rpm or 10 × g for precise protocol replication
• Real-time RCF calculation based on actual rotor geometry and rotational speed—not nominal values—ensuring metrological traceability
• Programmable timer range from 1 second to 99 hours; supports multi-step protocols with pause, hold, and auto-stop functions
• 40 user-programmable memory slots with password protection for method storage and operator accountability
• Brushless, maintenance-free motor with integrated thermal monitoring and automatic power-down after idle timeout
• Automatic rotor recognition and overspeed protection compliant with EN 61010-2-020
• Double-locking lid mechanism with mechanical interlock, emergency manual release, anti-drop hinge, and transparent inspection window
• Stainless-steel centrifuge chamber (AISI 304), autoclavable rotors and adapters (121 °C, 20 min), and removable rotor assembly with closed-lid access
• Active internal airflow management to limit temperature rise during extended runs

Sample Compatibility & Compliance

The Digtor 21 col accommodates standard conical tubes (15–50 mL), universal centrifuge tubes (up to 60 mL), and custom adapters for specialized containers used in regenerative medicine workflows. Its 4 × 60 mL capacity supports parallel processing of adipose aspirates, bone marrow harvests, or peripheral blood units. The instrument conforms to key international safety and electromagnetic compatibility standards: EN 61010-1 (general safety), EN 61010-2-020 (particular requirements for centrifuges), EN 61326-1 and -2-6 (EMC for laboratory equipment), and EU directives including RoHS (2011/65/EU), WEEE (2012/19/EU), EMC (2014/30/EU), LVD (2014/35/EU), and IVDD (98/79/EC). It supports audit-ready operation in GLP/GMP contexts through timestamped parameter logging and programmable security controls.

Software & Data Management

While the Digtor 21 col operates via embedded microprocessor control without external software dependency, all operational parameters—including speed, RCF, time, ramp profiles, and error logs—are stored internally with timestamping. Password-protected program recall ensures procedural fidelity across shifts and operators. Event-driven notifications (audible alerts + screen messages) report lid status, imbalance detection, overtemperature warnings, and completion signals. All configuration changes are recorded in non-volatile memory, supporting traceability per FDA 21 CFR Part 11 principles when integrated into validated lab information systems (LIMS) via optional RS-232 or analog output modules.

Applications

• Clinical isolation of stromal vascular fraction (SVF) from lipoaspirates in autologous regenerative therapies
• Routine preparation of PRP and platelet-poor plasma (PPP) for orthopedic and dermatologic applications
• Blood banking workflows: separation of packed red cells, buffy coat, and platelet concentrates
• Microbiological sample concentration prior to nucleic acid extraction or culture inoculation
• Preparative centrifugation of extracellular vesicles and exosomes from conditioned media
• Quality control testing of cell suspensions in biomanufacturing and ATMP (Advanced Therapy Medicinal Product) development

FAQ

What is the maximum RCF achievable with the Digtor 21 col?

The maximum relative centrifugal force is 1801 × g at 3000 rpm with the standard fixed-angle rotor.
Can the rotor be sterilized using autoclaving?

Yes—both the rotor and all compatible adapters are fully autoclavable at 121 °C for 20 minutes.
Does the centrifuge support real-time RCF adjustment during operation?

Yes—RPM and RCF can be modified dynamically while spinning, with immediate recalculation and display.
Is imbalance detection performed before or during rotation?

ULS performs pre-run imbalance verification and continuously monitors during acceleration; automatic shutdown occurs if imbalance exceeds safety thresholds.
What safety certifications does this model carry?

It bears CE marking per applicable EU directives and complies with EN 61010-1, EN 61010-2-020, EN 61326-1, and EN 61326-2-6.
