Precision Particle Standards – Expertise You Can Trust
At microParticles GmbH, we specialize in high-quality particle standards that support precision measurement, instrument calibration, and quality assurance across industrial, pharmaceutical, clinical, and scientific applications.
Particle Size Standards:
are essential for calibrating instruments like flow cytometers, laser diffraction devices, and disc centrifuges, and are widely used in method validation, uncertainty analysis, and filter testing.
Key Features:
- Traceable to primary reference materials of the National Institute of Standards and Technology (NIST/USA) and European Institute for Reference Materials and Measurements (IRMM/Belgium)
- characterized using: TEM, SEM, Differential Sedimentation, Electrical Sensing Zone Method.
- Highly colloidal stability
For accurate particle quantification, we offer:
Particle Count Standards:
- with 10⁶ particles/ml
- using 10 µm polystyrene microspheres in a stabilized aqueous suspension
- Certified via Beckman Coulter Multisizer 4e
- available in 10 ml and 15 ml vials, with custom options on reques
