Texwipe STX764T Sterile Dry Collection and Transport System (Polyester Swab + Labeled Transport Tube)

Texwipe STX764T is a sterile, ready-to-use dry collection and transport swab system built for diagnostic sampling, environmental monitoring, DNA sampling, and surface sampling where the integrity of the sample matters as much as the swab. Each unit pairs a 100% USP-grade spun polyester swab head with a flexible polystyrene handle (bonded with an aqueous/water-based adhesive), then places the swab into a medical-grade transport tube engineered to protect the specimen during handling and transit to the lab. The design intent is controlled, repeatable sampling with a closed, labeled container that reduces mix-ups, preserves sterility confidence, and supports chain-of-custody discipline for regulated or investigation-driven workflows.

Sterile-program note: STX764T units use a tube-and-cap system with tamper-evident labeling, lot/expiration marking, and case-level documentation (Certificates of Irradiation and Compliance). This is commonly selected when teams need sterile sampling that can be introduced with minimal handling risk and transported in a sealed, labeled container (dry format; no media in the tube).

About the Manufacturer:

Texwipe (an ITW company) is a worldwide leader in contamination-control consumables and sterile sampling tools. In the STX764T transport system, the manufacturing focus is on consistent geometry (high-precision automated processes), controlled packaging, and a closure system engineered to protect the specimen during handling and transport—reducing ambiguity around sterility, seal integrity, and traceability.

SOSCleanroom (SOS) supports this discipline through a close working relationship with Texwipe centered on continuity of supply, clean documentation handoff, and practical program-fit guidance—so sterile sampling methods stay stable, repeatable, and audit-ready without last-minute substitutions.

STX764T Features:

Ready-to-use sterile dry collection and transport system designed to maintain integrity of sample collection and sample transport
Medical-grade LDPE molded cap securely holds handle for safety and sterility while sampling
Cap rings support a tight seal and help protect against contamination during transport
1 mm thick medical-grade polypropylene tube with seamless molded round-bottom design
Tamper-evident seal on tube label supports point-of-use integrity confidence
Gamma irradiated to 10^-6 SAL in accordance with ANSI/AAMI/ISO 11137; sterile validated according to AAMI guidelines
Lot code and expiration date clearly marked on each tube
Certificates of Irradiation and Compliance attached to each case confirm irradiation dose met specifications
High-precision automated processes support exacting, consistent tolerances
Tested for endotoxins, ions, and Non-Volatile Residue (NVR)
Packaging labeled for global use

STX764T Benefits:

Protects the result, not just the workflow: The sealed, labeled tube reduces transport-driven contamination risk and helps prevent mix-ups when samples move from point of collection to the lab
Stronger chain-of-custody discipline: Tube-level lot and expiration marking plus tamper evidence supports investigation readiness and controlled inventory practices
Repeatable sampling access: 6.102" (155 mm) overall length helps reach difficult sampling sites while reducing collateral contact on surrounding surfaces
Method-friendly dry format: Dry transport configuration aligns with many lab intake expectations (no media in the tube); wetting/neutralizer steps remain method-defined
Controlled low-linting behavior (process-dependent): Spun polyester supports effective collection, but no swab is truly “lint-free” across all surfaces and stroke pressures

Common Applications:

Diagnostic sampling
Environmental monitoring (surface sampling in controlled areas)
DNA sampling
Surface sampling of touchpoints, seams, ports, hinges, and irregular geometries
Picking up fine powders or residues for downstream lab analysis (method-defined)
Controlled cleaning with solvents such as IPA or acetone (qualify compatibility and exposure limits to your method)

Best-Practice Use:

Tube-first discipline: Confirm the tamper-evident seal is intact before opening; if compromised, quarantine per your sampling SOP.
Define the method: Standardize swabbed area, stroke count, stroke direction, pressure, and contact time so trends are comparable across operators and shifts.
Avoid re-contact: Do not let the swab head touch gloves, bench surfaces, or tube exterior during collection; treat the tube as the sterile transport barrier.
Control wetting (if used): If your protocol calls for a wetting agent/neutralizer, use controlled aliquots. Over-wetting can smear material and change recovery.
Close immediately: Re-cap firmly after collection to protect sample integrity; confirm the cap interface is fully seated before transport.
Document what matters: Record tube lot/expiration and sampling site/area details; this reduces ambiguity during investigations and CAPA work.
Standards awareness: Align sampling documentation and controlled-environment expectations to your program requirements (ISO: https://www.iso.org/standard/53394.html; FDA: https://www.fda.gov; ASTM: https://www.astm.org; IEST: https://www.iest.org).

Selection Notes (STX764T vs. Other Options)

Transport system vs. sleeve-packed sterile swab: Choose STX764T when you need a closed, labeled transport container for chain-of-custody and protected transit. Choose sleeve-packed sterile swabs when transport containment is handled by your own kit/container method.
Spun polyester vs. foam/knit heads: Spun polyester can be well-suited for collection and lab elution workflows, but it does not behave like thermally bonded cleanroom swabs selected for ultra-critical residue control. Match the swab head to your downstream recovery method and acceptance criteria.
Solvent compatibility: If your method uses solvents stronger than IPA, qualify the polystyrene shaft and adhesive bond under real dwell time, temperature, and exposure conditions—or specify a different swab construction aligned to that chemistry.
Investigation readiness: When sampling results can trigger investigations, deviations, or batch decisions, tube-level lot/expiration marking and tamper evidence are operational advantages.
