Calibration Microspheres for Flow Cytometry
Calibration microspheres are essential for the routine optimization and quality assurance of flow cytometers. To ensure the highest levels of accuracy in your flow cytometry workflows, we offer:
-
Size Calibration Standards: For precise scaling and verification of forward scatter (FSC) and side scatter (SSC) signals.
-
Fluorescence Signal Standards: Designed for the intensity calibration and sensitivity monitoring of fluorescence channels.
These microspheres ensure accurate signal detection, consistent data collection, and reliable instrument performance across all laboratory experiments.
Quality Criteria and Traceability
Our particle size standards are developed and characterized in accordance with the highest international metrological requirements:
-
Metrological Traceability: Fully traceable to the International System of Units (SI), including reference materials from the National Institute of Standards and Technology (NIST/USA) and the Joint Research Centre (formerly IRMM/Belgium).
-
Exceptional Monodispersity: Ultra-narrow size distributions with a Coefficient of Variation (CV) < 2% for the majority of our product range.
-
Geometric Precision: Perfectly spherical morphology with a symmetrical peak (Skewness ≈ 0) to ensure unambiguous measurement results.
-
Colloidal Stability: Engineered for high stability in suspension to prevent aggregation and ensure long-term reproducibility.
-
Regulatory Compliance: Produced and characterized in alignment with ISO standards and Certified Reference Material (CRM) guidelines.
To conclude:
By adhering to these rigorous standards, microParticles GmbH provides particle size standards that meet the most demanding international metrological criteria. Our commitment to precision ensures that our standards are among the most accurately characterized products currently available on the global market.
By combining continuous process improvement with state-of-the-art characterization, we deliver premium products of the highest quality to our global customers.
