Keebio Palm-Sized Centrifuge Series

Overview

The Keebio Palm-Sized Centrifuge Series is a compact, high-efficiency microcentrifuge engineered for rapid, precise sedimentation of microliter-scale biological samples in molecular biology, clinical diagnostics, and quality control laboratories. Operating on the principle of radial acceleration-induced sedimentation, these instruments generate controlled centrifugal force (RCF) to separate suspended particles—such as nucleic acids, proteins, cellular debris, or bacterial pellets—based on density and size differences within low-volume tubes. Designed specifically for routine handling of PCR tubes, spin columns, and microfuge tubes (0.2–2.0 mL), the series delivers reproducible performance across a broad speed range (3,000–10,000 rpm), enabling both quick spin-downs and extended pelleting protocols without requiring benchtop footprint redistribution.

Key Features

• Integrated Universal Rotor Architecture: A single, precision-machined aluminum rotor accommodates all standard microtube formats—including 0.2 mL PCR strips (2 × 8-position), 0.5 mL, 1.5 mL, and 2.0 mL conical or round-bottom tubes—via snap-in silicone adapters. Eliminates cross-contamination risk and mechanical wear associated with frequent rotor swaps.
• Intelligent Lid Interlock System: The transparent polycarbonate lid rotates up to 95° for unobstructed access and incorporates a safety switch that halts rotation immediately upon opening and initiates spin-up only after full closure—fully compliant with IEC 61010-1 mechanical and electrical safety requirements.
• Preset & Programmable Timing: Dedicated soft-touch buttons provide instant selection of fixed-duration spins (3 s, 10 s, 30 s) for rapid sample consolidation; an extended digital timer supports continuous operation or precise intervals from 0 to 9999 seconds, suitable for gradient pelleting or column-based purification steps.
• Thermally Stable Brushless DC Motor: Delivers consistent torque and minimal heat generation during prolonged use. Rated for >10,000 hours MTBF, ensuring long-term reliability under daily QC or high-throughput lab workflows.
• Compact Ergonomic Form Factor: At just 156 × 176 × 121 mm and weighing 1.6 kg, the unit fits comfortably inside biosafety cabinets, cold rooms, or crowded laminar flow hoods—ideal for point-of-use centrifugation adjacent to pipetting stations or thermal cyclers.

Sample Compatibility & Compliance

The Keebio series supports standardized consumables used across ISO 15195-accredited clinical labs and GLP-compliant research environments. Tube compatibility includes certified DNase/RNase-free polypropylene microtubes (Eppendorf-type), PCR strip tubes (0.2 mL, 8-well format), and spin-column assemblies used in nucleic acid extraction kits (e.g., QIAamp, NucleoSpin). All models meet CE marking requirements per Directive 2014/30/EU (EMC) and 2014/35/EU (LVD), and conform to IEC 61010-1:2010 for protection against electric shock, mechanical hazards, and abnormal temperature rise. No internal battery or wireless module is included—ensuring full traceability and audit readiness for FDA 21 CFR Part 11–aligned documentation systems.

Software & Data Management

This is a stand-alone, hardware-controlled centrifuge with no embedded firmware-based data logging or network interface. All operational parameters—including speed, time, and RCF—are set manually via front-panel controls and are not stored or exportable. This design aligns with ISO/IEC 17025:2017 Clause 7.7.1 (control of equipment records) by eliminating software-dependent calibration drift or versioning dependencies. Users maintain manual logbooks or integrate run records into LIMS via external timestamps, satisfying GLP audit requirements for instrument usage traceability without introducing electronic record complexity.

Applications

• Rapid spin-down of condensation in PCR tube caps prior to thermocycling
• Post-extraction clarification of lysates in DNA/RNA isolation workflows
• Microfiltration support for syringe-driven spin columns (e.g., desalting, buffer exchange)
• Bacterial pellet collection from small-volume cultures (≤2 mL)
• Centrifugal separation of immunoassay reagents in point-of-care test development
• Pre-analytical sample conditioning for HPLC or mass spectrometry sample prep

FAQ

What tube formats are supported without additional accessories?
Standard configurations include adapters for 0.2 mL, 0.5 mL, 1.5 mL, and 2.0 mL microcentrifuge tubes. PCR strip compatibility (2 × 8-position) requires the optional Keebio PCR rotor kit—available separately for Keebio-4K, Keebio-6K, and Keebio-10K+ models.
Is the centrifuge compatible with 110 V power supplies used in North America?
Yes—dual-voltage input (110–220 V, 50–60 Hz) enables seamless deployment in both EU and North American laboratory infrastructures without transformers or voltage converters.
Does the unit require routine calibration per ISO/IEC 17025?
While no formal recalibration is mandated for speed or time accuracy due to its analog control architecture, users should verify rotational speed annually using a calibrated handheld tachometer per ISO 17025 Clause 6.4.3—and document results in equipment maintenance logs.
Can the centrifuge be operated inside a refrigerated environment?
Yes—rated for ambient operation between 5 °C and 40 °C; however, condensation on internal components may occur below 10 °C. For sustained cold-room use, allow thermal equilibration for ≥30 minutes before operation.
Are spare rotors and adapters available through Keebio’s authorized distribution network?
Yes—original-equipment adapters for 0.2 mL PCR strips, 0.5 mL tubes, and dual-capacity 1.5/2.0 mL rotors are stocked and shipped globally with traceable serial-numbered packaging.
