Gel Card Centrifuge
Specialized benchtop centrifuge for gel card testing with 24-card capacity, 4000 rpm maximum speed, and programmable timing for blood banking and immunohematology applications.
The Gel Card Centrifuge is a specialized laboratory centrifuge designed for gel card testing applications in blood banking, immunohematology, and clinical diagnostics. This compact benchtop instrument accommodates up to 24 gel cards simultaneously, providing controlled centrifugal separation at speeds up to 4000 rpm with ±20 rpm precision. The unit features programmable timing from 1 second to 999 minutes, enabling precise protocol execution for antigen-antibody reactions and blood typing procedures.
Operating at noise levels ≤60 dB, this centrifuge maintains a quiet laboratory environment while delivering consistent performance for gel card agglutination assays. The universal power supply (AC110-220V, 50/60Hz) and compact footprint (480×358×270mm) make it suitable for diverse laboratory settings requiring reliable gel card processing capabilities.
How It Works
The gel card centrifuge operates on the principle of controlled centrifugal separation to enhance antigen-antibody reactions within specialized gel matrix cards. During centrifugation, the applied centrifugal force drives red blood cells through the gel medium, where specific antibodies are immobilized. Positive reactions result in agglutinated cells trapped at various levels within the gel column, while negative reactions allow cells to pellet at the bottom.
The precise speed control (±20 rpm accuracy) and programmable timing ensure reproducible separation conditions across different assay protocols. The rotor design accommodates standard gel card formats, maintaining uniform centrifugal force distribution across all 24 card positions. This controlled environment enables clear differentiation between positive and negative reactions, critical for accurate interpretation of blood typing and compatibility testing results.

Practical Tips
Verify speed accuracy quarterly using a tachometer or speed verification kit to ensure precise centrifugal force delivery.
Why: Speed accuracy directly affects gel card assay interpretation and result reproducibility.
Clean the rotor and chamber weekly with mild detergent and inspect for gel card residue that could affect balance.
Why: Residue buildup can cause vibration and interfere with proper card seating during centrifugation.
Allow gel cards to reach room temperature before centrifugation and avoid overpacking the rotor beyond rated capacity.
Why: Temperature equilibration ensures consistent viscosity while proper loading prevents mechanical stress and ensures even force distribution.
If excessive vibration occurs, check rotor balance by redistributing cards and ensure the unit is level on a stable surface.
Why: Vibration can affect separation quality and cause premature wear of centrifuge components.
Document centrifugation parameters for each assay type to establish standardized protocols and ensure result consistency.
Why: Standardized parameters enable protocol validation and support quality assurance requirements.
Always ensure the lid is properly closed and locked before starting centrifugation, and never attempt to open during operation.
Why: The lid interlock system prevents operator injury from rotating components and maintains proper centrifugation conditions.
Schedule annual professional service calibration to verify timing accuracy and mechanical integrity.
Why: Regular calibration maintains instrument specifications required for regulatory compliance and quality assurance.
Use only gel cards within their expiration dates and store according to manufacturer specifications before centrifugation.
Why: Expired or improperly stored gel cards can produce false results regardless of centrifuge performance.

Compliance
What gel card formats are compatible with this centrifuge?
The rotor adapter accommodates standard gel card formats used in blood banking. Consult product datasheet for specific card dimensions and compatibility requirements.
How do I determine optimal centrifugation parameters for different assays?
Follow gel card manufacturer protocols for speed and timing. Typical blood typing requires 1-5 minutes at 1000-3000 rpm, while antibody screening may require different parameters.
What maintenance is required for consistent performance?
Regular cleaning of the rotor and chamber, periodic speed verification, and annual service calibration ensure reliable operation and accuracy.
Can this centrifuge be used for other applications besides gel cards?
This unit is specifically designed for gel card applications. The rotor adapter and chamber configuration are optimized for gel card dimensions and may not accommodate other tube formats.
How does the noise level compare to standard laboratory centrifuges?
At ≤60 dB, this unit operates significantly quieter than high-speed centrifuges, making it suitable for patient care areas and open laboratory environments.
What happens if there's a power interruption during centrifugation?
Consult user manual for power failure procedures. Most protocols can be repeated if interrupted, but specific gel card assays may require fresh samples for accurate results.
How do I ensure balanced loading for optimal performance?
Distribute gel cards evenly around the rotor positions. If running fewer than 24 cards, place them in opposing positions to maintain rotor balance and prevent vibration.
