Supporting Reliable, Compliant Facility and Utilities

Two areas of control

Maintaining a facility in a state of control is essential to protecting product quality, patient safety, and regulatory compliance.

Effective environmental monitoring, cleaning, and qualification programs help identify changes before they become contamination events, failed batches, or costly investigations.

A well-controlled facility also reduces operational costs by minimizing repeat testing, production delays, rejected product, emergency remediation, and unplanned downtime. By understanding trends and addressing risk early, organizations can maintain reliable operations while avoiding the far greater expense of responding after control has been lost.

Utility services

Maintaining critical utility systems is essential to protecting product quality, patient safety, and regulatory compliance

Routine testing of utilities helps identify microbial, chemical, or performance changes before they affect manufacturing operations or product integrity.

A well-controlled utility program also reduces costs by preventing failed batches, repeat testing, emergency sanitization, production delays, and unplanned system shutdowns. By monitoring trends and addressing changes early, organizations can maintain reliable operations and avoid the significantly greater cost of responding after a utility system has fallen out of control.

Clean Steam & Compressed Gas

Clean steam and compressed gas systems can directly influence product quality, equipment performance, and controlled manufacturing environments. PlumGXP provides testing for microbial contamination, endotoxin, condensate quality, particulates, moisture, oil, and other applicable quality attributes to help verify that these critical utilities remain suitable for their intended use. Routine testing and trend review can identify emerging system changes before they lead to contamination risks, process disruption, or costly investigations.

Water Systems

PlumGXP supports pharmaceutical water system qualifications and routine monitoring of performance. Testing capabilities include microbial enumeration, Total Organic Carbon (TOC), conductivity, pH, nitrates and bacterial endotoxins, as applicable to the water grade and client requirements. Biofilms can develop within pharmaceutical water systems when microorganisms attach to internal surfaces and form protective communities that are difficult to remove once established. Routine testing detect subtle increases or recurring organisms before the system reaches an action level, allowing earlier investigation, sanitization, and corrective action.

Autoclave

Autoclave validation and routine cycle monitoring help demonstrate that steam sterilization processes consistently achieve the required level of microbial inactivation. PlumGXP supports studies using chemical and biological indicators, including biological indicator population verification, log-reduction analysis, and positive- and negative-control evaluation. These services help confirm indicator performance, verify cycle effectiveness, and provide documented evidence that sterilization processes remain reliable and suitable for their intended use.

Keep Critical Utilities Under Control

PlumGXP helps verify the quality and reliability of pharmaceutical water, clean steam, compressed gases, and sterilization systems so potential issues can be identified early—before they affect product quality, compliance, or operations.
