Particle Counters

Particle counters are precision monitoring instruments used to detect and quantify airborne particulate matter in cleanrooms, controlled environments, and pharmaceutical manufacturing spaces. These devices play a critical role in ensuring compliance with regulatory standards such as ISO 14644, EU GMP Annex 1, and FDA guidelines, which mandate strict limits on airborne contaminants to protect product integrity, patient safety, and the overall sterility of manufacturing processes. By providing real-time data on airborne particles, particle counters enable laboratories and production facilities to maintain the highest standards of cleanliness and operational control. Used extensively in pharmaceutical production, semiconductor manufacturing, biotechnology, aerospace, and hospital sterile compounding, particle counters are essential tools for validating cleanroom classifications, performing environmental monitoring, and supporting aseptic process qualifications. These instruments detect particles typically in size ranges of 0.3 to 10 microns, including dust, microorganisms, and other potential contaminants that may compromise sensitive operations. Modern particle counters are available in both portable and fixed (continuous monitoring) formats. Portable units are used for routine cleanroom qualification and troubleshooting, while remote, facility-integrated systems provide continuous data logging and instant alerts for deviation from cleanroom standards. Many systems offer features such as multi-channel sizing, data storage, USB or Ethernet connectivity, ISO and EU GMP reporting formats, and integration with environmental monitoring systems (EMS) or laboratory information management systems (LIMS). By identifying trends or spikes in particle concentration, these devices allow for proactive maintenance, contamination source investigation, and process optimization. Their use is essential for cleanroom certification, routine monitoring, and supporting root cause analysis during out-of-specification (OOS) events. At Wasteless Bio, we supply surplus and refurbished particle counters from top-tier manufacturers. Each listing includes specifications such as flow rate, detection range, compliance standards, reporting capabilities, and integration options. Sourcing particle counters through Wasteless Bio offers a cost-effective way to uphold rigorous cleanroom standards while promoting sustainable lab practices through equipment reuse and circular procurement.
