LSUG Training

The Life Science User Group (LSUG) runs a regular training program to keep users updated with the latest changes in legislation and international standards including ISO 21501 and ISO 14644. These are hosted at local venues and focus on practical hands on particle counting activities, while also leaving time to exchange experiences informally with industry experts.

Local Service and On-Site Calibration

Our organization focuses on providing a premier level of service and technical support since we recognize that this is a critical point for production sites. Where possible we provide scheduled on-site calibration for particle counters to avoid the “data gap” or downtime caused by taking particle counting instruments off site. Our technical experts can help with your IQ/OQ validation, SOP assistance and ISO 21501-3 compliant calibrations for your HIAC and MET ONE particle counters.
