California‑based SafeTraces is a biotechnology company on a mission to pathogen-proof indoor environments. Their flagship veriDART platform uses patented DNA-tagged aerosol tracers — deployed via pre‑filled, single‑use syringes — to measure and verify HVAC system performance, air quality, and infectious aerosol risk in real-world buildings. Clients include major hospital systems, Fortune 100 tech companies, public school districts, federal agencies, and international airports.
To conduct a veriDART field assessment, a certified service professional needs a sterile, pre‑filled syringe loaded with a tightly controlled volume of SafeTraces' proprietary tracer liquid. That syringe has to arrive at the job site sealed, sterile, and ready to dispense — every single time.
SafeTraces needed a contract manufacturing partner who could make that happen reliably, at startup scale, and fast.
The Challenge: Sterile, Small-Volume Syringes for Real-World Controlled Environments
SafeTraces came to Advasaf with a technically specific problem:
Their veriDART tracer workflow required small-volume syringes filled with a precise liquid payload — each dose had to be accurate and repeatable so field technicians could get consistent, data-grade results across different buildings and test environments.
Each syringe needed to be filled, labeled, pouched, sealed, and sterilized — with no live organisms remaining in the final pack — so the product could be used safely in healthcare facilities, biopharma labs, schools, and critical infrastructure settings where SafeTraces' clients have strict sterility and biosecurity expectations.
The SafeTraces team did not have in-house expertise to answer core questions:
Which sterilization cycle would reliably eliminate microorganisms without damaging the syringe body or degrading the liquid payload?
What self-sealing pouch and labeling configuration would maintain the sterile barrier from the manufacturing floor all the way to a technician's hands in the field?
How do you document all of this inside a quality system that can withstand regulatory and customer audit scrutiny?
For a startup building commercial credibility with enterprise and government clients — hospitals, federal agencies, Fortune 100 companies — a contamination event, a failed audit, or a delayed shipment is not just an operational problem. It is a reputational one. SafeTraces needed a partner who could take complete ownership of this workstream, not just run materials through a machine.
Why SafeTraces Selected Advasaf
SafeTraces selected Advasaf as their sterile contract manufacturing partner because Advasaf could deliver the full package under one roof:
Precise small-volume liquid filling into syringes, with traceability markings applied at the lot level.
Self-sealing medical pouch placement and validated heat-seal closure so the sterile barrier is intact from production through field deployment.
Sterilization cycle development, Bowie-Dick style test pack validation, and biological indicator (BI) testing — all documented within Advasaf's ISO 13485-certified quality management system.
Startup-friendly small-batch runs with the same rigor and documentation standards expected by regulated healthcare and life-science customers.
This meant SafeTraces could hand off the entire sterile syringe program and stay focused on their core competency: building the biotech platform, expanding the veriDART certified professional network, and growing commercial relationships with enterprise clients.
The Solution: From Bulk Liquid to Sterile, Field-Ready Single-Use Syringes
Advasaf structured the program in five integrated workstreams:
1. Precise Filling and Single-Use Delivery
Filled each syringe with a tightly controlled liquid volume matched to SafeTraces' dosage specifications for their veriDART tracer workflows.
Verified that the dispensing force stayed within acceptable limits so field technicians could use the product reliably in buildings — hospitals, offices, school classrooms, transit terminals — without variation.
Configured each unit as a true single-use delivery system, eliminating dose-measurement error and cross-contamination risk that would be introduced by multi-use vials in a field setting.
2. Pouching, Labeling, and Sealing
Placed each filled syringe into a self-sealing medical pouch — creating a closed sterile environment where "whatever is inside stays inside" from the point of seal through final use.
Applied lot-level labels and back-of-pouch markings so every unit in the field is fully traceable back to a specific manufacturing batch and sterilization run.
Pouch configuration chosen to maintain barrier integrity across the shipping, storage, and field-deployment conditions SafeTraces' certified professionals encounter on the job.

3. Sterilization Strategy, Cycle Development, and Validation
Developed a sterilization "recipe" — balancing temperature, pressure, and exposure time — that achieved full microbial kill without damaging the syringe components or altering the liquid payload that SafeTraces' tracer technology depends on.
Used standardized test packs (Bowie-Dick style) to confirm effective air removal and steam penetration before processing any live SafeTraces product, reducing cycle-failure risk.
Ran biological indicator (BI) testing to provide documented, auditable evidence of sterilization efficacy.
Documented the entire program within Advasaf's ISO 13485 quality management system, producing reports SafeTraces could drop directly into their own technical files and customer audit packages.

4. Kitting Capability for Future Program Expansion
Demonstrated the ability to take SafeTraces' bulk materials and convert them into tray-and-pouch kits, establishing the foundation for future veriDART field kits that could combine the syringe with other accessories needed for controlled-environment assessments.
This capability positions SafeTraces to scale their product offering without having to find and qualify additional manufacturing partners.
5. Three-day Cycle Time, Delivered Under Budget
Structured the entire program — from receipt of SafeTraces' materials to release of sterile, labeled, pouched, and validated syringes — in a three-day cycle, compared to the 6–8 week timelines typical for most contract sterilization projects.
Optimized batch sizes, test load configurations, and documentation workflows so the project came in under budget, freeing capital that SafeTraces was able to redeploy into commercial growth, veriDART platform development, and expansion of their certified professional network.
This faster, leaner delivery model is especially valuable for high-growth startups where capital efficiency and speed-to-market directly affect investor confidence and customer commitments.

The Outcome: Launch-Ready, Validated Syringes SafeTraces — Faster and Under Budget
With Advasaf as their sterile manufacturing partner, SafeTraces was able to:
Move faster than the industry standard. Each batch of sterile, labeled, pouched syringes was ready in three days — not the 6–8 weeks SafeTraces would have faced with most contract sterilization providers. For a startup racing to build commercial momentum with hospital systems, federal agencies, and Fortune 100 clients, that time savings directly accelerated their go-to-market timeline.
Save cost and protect capital. The program came in under budget, without cutting corners on quality. That cost efficiency gave SafeTraces more runway to invest in growing their veriDART certified professional network, expanding PathogenSentinel™ commercialization, and pursuing government contracts like their recently awarded ARPA-H BREATHE Program selection.
Meet the audit bar for enterprise and government clients. Sterilization cycles were verified with standardized test packs and BI testing, and the full program was documented within an ISO 13485 QMS. SafeTraces could present that documentation directly to hospital infection-control teams, biopharma quality departments, and federal procurement officers — without having to build that infrastructure internally.
Scale confidently. By establishing a repeatable, validated sterile syringe program — including kitting capability for future field kit configurations — SafeTraces now has the manufacturing backbone to support their growth across K-12 schools, healthcare systems, corporate real estate portfolios, and biodefense and critical infrastructure clients.
Stay focused on what they do best. Rather than diverting engineering and operations resources into sterile filling, packaging, and sterilization validation, SafeTraces kept their team focused on the biotech platform, the data analytics, and the commercial relationships that drive their business. Advasaf closed the gap.
What This Means for Other High-Growth Startups
SafeTraces is not unique in this situation. Many biotech and medtech startups developing products for healthcare, biopharma, life sciences, or safety-critical controlled environments reach a point where their product requires sterile packaging and documentation — but their team was hired to build the technology, not run a cleanroom.
Advasaf specializes in exactly this moment. Whether the need is small-batch sterile filling, pouch-and-seal packaging, steam sterilization with full cycle documentation, or end-to-end ISO 13485-backed kitting programs, Advasaf provides the manufacturing infrastructure that lets high-growth companies move at startup speed without compromising the quality standards their customers demand.
