Fisherbrand Microplate Centrifuge with 4 Plate Inserts

Fisherbrand Microplate Centrifuge with 2-Plate Rotor and 4 Plate Inserts (14-955-300)

The Fisherbrand Microplate Centrifuge (14-955-300) is a compact, quick-spin benchtop centrifuge specifically designed to flick droplets and condensation down from microplate walls and adhesive seals prior to PCR amplification or optical assay reading. Featuring a vertical rotor orientation that holds plates side-by-side without requiring plate lids or sealing tape during operation, this unit prevents sample evaporation errors and cross-well contamination. Equipped with an efficient, fixed-speed motor delivering up to 2,500 RPM (approx. 500 x g), the centrifuge features an immediate electronic brake that brings the rotor to a complete stop within seconds of opening the lid. Supplied complete with 4 removable plate adapters/inserts, this system accommodates standard 96-well, 384-well, skirted, semi-skirted, non-skirted, and deep-well PCR plates for essential pre-analytical sample preparation.

Technical Performance & Structural Attributes

• Vertical Rotor Loading Architecture: Holds two microplates vertically in place using centrifugal force, preventing liquid sloshing and eliminating the need for sealing film during quick spins.
• Instant Electronic Braking: Automatically engages rapid deceleration when the lid latch is released, minimizing cycle downtime between plate runs.
• Compact Benchtop Footprint: Conserves valuable benchtop space inside PCR preparation cabinets, laminar flow hoods, and mobile testing stations.
• Removable Plate Inserts Included: Comes equipped with 4 interchangeable adapter inserts to securely support non-skirted PCR plates and thin-walled microplates without deformation.
• Quiet Motor Operation: Low-vibration brushless motor runs quietly to maintain a comfortable working environment in high-throughput labs.

Key Benefits & Applications

• Pre-PCR Liquid Pooling: Rapidly spins down micro-liter droplets hanging on well walls to ensure accurate reagent volumes and uniform thermal transfer during PCR cycles.
• Assay Preparation & Plate Reading: Eliminates air bubbles trapped in multi-well plate liquid columns prior to optical absorbance or fluorescence plate reader measurements.
• High-Throughput Convenience: Vertical loading allows rapid insertion and removal of plates without tedious balancing procedures required by standard swinging-bucket centrifuges.
