In-Line Quality Control: The Methodology Eserplex Has Perfected Over 20 Years
Introduction: Beyond Final Inspection
In the pharmaceutical industry, inspecting the finished product is not enough. True excellence is built at every stage of the process. At Eserplex, we understood this more than two decades ago, and since then we’ve refined an in-line quality control system that has transformed the way we produce.
From reactive to preventive
Traditional final inspection detects errors—we prevent them. We implement continuous checks during production: dimensions, attributes, and technical compliance in real time. Every stage is documented and traceable, ensuring that what leaves our plant is flawless from the start.
Our internal methodology
Eserplex developed its own in-line quality control protocol, aligned with ISO 9001 standards and enhanced through years of experience. Our team is continuously trained to maintain the standards our clients demand. As a result, our complaint rate is below 0.2%.
What our clients gain
- Significant reduction in waste
- Guaranteed compliance in audits
- Deliveries without surprises or delays
- Operational and reputational confidence
As our CEO, Patricia Escallón, states: “Quality control is not audited at the end—it is embedded in every step of the process.”
