ELPRO LIBERO Loggers and liberoMANAGER 3.0

ELPRO-BUCHS AG is a Swiss provider of GxP-compliant temperature and condition monitoring for pharma and life sciences, headquartered in Buchs SG and active since 1986. It combines in-house hardware, software, GxP consulting, temperature mapping and calibration services, with 8 locations and 4 accredited calibration labs, and marked 10 years of presence in Asia in 2025.

For shipments, LIBERO Cx single-use USB and multi-use Bluetooth PDF loggers and LIBERO Gx cellular real-time loggers feed one validated cold chain database, liberoMANAGER 3.0. The software covers -200 °C to +400 °C, calculates stability budgets continuously, raises real-time alarms in transit and supports automatic data submission and product release at receiving sites. Customers are pharmaceutical, life sciences and logistics companies handling from a few hundred to tens of thousands of shipments per year.

• LIBERO Cx PDF loggers: single-use USB and multi-use Bluetooth loggers that create readable reports without extra software.
• LIBERO Gx real-time loggers: cellular IoT devices reporting temperature, humidity, alarms and location in transit.
• liberoMANAGER 3.0 database: one validated cold chain database for all LIBERO loggers from -200 °C to +400 °C.
• Stability budget engine: continuous calculation of remaining allowable excursion time per product.
• Automated receiving and release: automatic data submission and real-time product evaluation at receiving sites.
• Dashboards and API: custom KPI dashboards and API integration with shipping systems.

• A Vietnamese pharmaceutical importer can monitor vaccine and biologic shipments from Europe with real-time loggers and release goods faster on arrival.
• A pharma distributor can manage USB loggers for domestic deliveries to hospitals in one GDP-compliant database.
• A clinical trial logistics provider can track temperature-sensitive samples between sites in the region.

• Real-time alarms and continuous stability budget calculation help teams act before quarantines and product losses occur.
• Software-based alarming for mixed loads reduces the number of loggers needed per shipment.
• LIBERO Gx real-time loggers can be used on a usage basis, with ELPRO handling delivery, pick-up and refurbishment.
• One GDP-compliant database simplifies audit preparation across all shipments and sites.

Pharma cold chains are moving from passive data loggers read after arrival to real-time monitoring and automated release, driven by GDP rules, biologics and vaccines. Pharmaceutical distribution in Southeast Asia, including GSP and GDP compliant warehouses and importers in Vietnam, increasingly needs validated monitoring data for audits and product release.
