Capabilities

Prove the Process. Then Build the System.

PuroGen validates process feasibility on its own platform before a custom system is engineered. R&D subcontract manufacturing gives you real validation data — and the confidence to commit capital.

Engagement Model

Two Phases. One Continuous Pathway.

Most sterilization engagements begin with a capital commitment before process feasibility is confirmed. PuroGen inverts that sequence. Prove the process first. Build the system once the data supports it.

1R&D Subcontract Manufacturing

Feasibility before capital.

PuroGen runs process development and proof-of-concept work on its own validated SteriFlex platform. Your material or device is processed, characterized, and tested under controlled conditions. The output is real validation data — not a demonstration.

Material compatibility testing

Cycle parameter optimization

Biological indicator challenges

Preliminary validation data package

Custom system specifications defined by data

2Custom System Engineering

Engineering defined by evidence.

Phase 1 data drives Phase 2 specifications. Chamber dimensions, cycle parameters, and validation scope are defined by what was proven — not estimated. The custom system is built to a validated process, not the other way around.

Bespoke chamber engineered for your portfolio

Parametric control configured to proven cycle parameters

IQ/OQ/PQ developed in parallel with engineering

ISO 22441-aligned documentation for all target markets

Installation and commissioning at your facility

The continuity advantage: Because Phase 1 is conducted on PuroGen's own validated platform, the data generated feeds directly into Phase 2 validation protocols. There is no translation gap between proof-of-concept and production — the same process chemistry, the same biological indicators, the same parameter logic. Phase 1 is not a pilot. It is the first chapter of the validation package.

Phase One

R&D Subcontract Manufacturing

PuroGen offers R&D subcontract manufacturing for organizations that need process feasibility confirmed before committing to custom system engineering. Work is conducted in-house on PuroGen's existing validated platform under rigorous documentation protocols.

Feasibility Assessment

Technical evaluation of your material, device, or substrate against VHP process parameters. Includes material compatibility screening and initial cycle development to confirm viability before any capital commitment.

Process Development

Systematic cycle development using PuroGen's existing validated SteriFlex platform. Parameters — concentration, temperature, humidity, dwell time, vacuum profile — are optimized for your specific application.

Material Compatibility Studies

Documented testing of material performance pre- and post-VHP exposure. Results inform chamber specifications and cycle parameters for the subsequent custom system build.

Preliminary Validation Data

Biological indicator challenges, sterility testing, and cycle reproducibility studies conducted during the R&D phase generate real validation data — not demonstration results. This data feeds directly into the IQ/OQ/PQ pathway.

Regulatory Pathway Mapping

Assessment of applicable standards (ISO 22441, FDA Category A, EU MDR) and documentation requirements for your target regulatory markets. Validation scope defined before engineering begins.

Proof-of-Concept Report

Structured documentation of R&D findings: process parameters, compatibility data, preliminary validation results, and recommended specifications for the custom system build.

The data generated in Phase 1 is not demonstration data. It is produced under the same rigorous protocols applied to production validation — and it feeds directly into the IQ/OQ/PQ evidence package for the custom system.

Load configuration engineering for maximum cycle efficiency
Internal fixture and rack design
Cleanroom and facility integration planning

Parametric Process Control

Adjustable VHP concentration and reagent dosing
Independent temperature control across operating range
Precise humidity and vacuum profile management
Programmable cycle sequencing and hold times

Operational Scope Notice

PuroGen's R&D and manufacturing services are available for all regulated materials and substrates except THC-containing biomass, which falls outside our current operational scope. Cannabis and hemp purification applications are served through PuroGen's BoxPurify platform.

Material Compatibility Assessment

Specific material compatibility is assessed during the Phase 1 R&D engagement. Materials not listed here are not necessarily incompatible — they require targeted feasibility evaluation. Contact PuroGen to discuss your specific material profile before engagement.

Begin

Start with a Feasibility Study

A feasibility study is the lowest-risk entry point into a custom VHP sterilization capability. Bring your material or device to PuroGen's platform. We run the process. You get the data. If the data supports a custom system, we build it — to the parameters the data defines.

If the data reveals constraints that require design changes, you learn that before committing to a capital project. That is the point. The feasibility study exists to inform the decision, not to justify it.
