In sterile and controlled areas, the “small jobs” create most of the investigations: a tacky residue at a gasket edge, a powder smear at a vial tray corner, or a swab that is too short and forces gloves to drag across a work surface. STX705P is built for those routine, inspection-day realities—sterile at point-of-use, individually packaged, and long enough to keep hands back while still giving you cotton’s absorbent “grab.”

Use it when the goal is pickup and transfer (sampling, particulate pickup, localized wipe-down) and the surface can tolerate cotton contact. If you are cleaning optics, coated sensors, or polished surfaces where fiber or streak risk is unacceptable, gate to a foam or knit-polyester cleanroom swab family instead.

• Sterile-area spot cleaning with common solvents (IPA is common; validate compatibility with the surface or coating).
• Environmental monitoring and routine diagnostic sampling workflows where a sterile, single-use swab is required at point-of-use.
• Pickup of fine powders or debris in corners, seams, and shallow recesses where wipes cannot maintain contact.
• Swabbing small parts, fixtures, and housings when tactile control matters more than ultra-low-linting performance.

• Sterile at point-of-use: Individually packaged peel-apart sleeves support aseptic transfer without in-house repackaging.
• Absorbency and pickup: Cotton is a strong choice for pickup and transfer when “grab” and sorbency matter.
• Long reach, better geometry control: The long polystyrene handle helps keep gloves and sleeves out of the work zone.
• Documented controls: Lot coding, expiration dating, and published contamination-characterization data reduce ambiguity during deviations.
• Consistent availability: SOSCleanroom supports ITW Texwipe programs with continuity of supply and documentation discipline to minimize last-minute substitutions.

• Head: 100% USP-grade spun cotton.
• Handle: Polystyrene handle for durability and reach.
• Head bond: Water-based adhesive bond (by design for spun cotton swabs).
• Sterilization: Gamma irradiated to a Sterility Assurance Level (SAL) of 10^-6 (per manufacturer claims tied to ANSI/AAMI/ISO 11137 references).
• Operator reality: Cotton is absorbent but can shed fibers if overworked, dragged across sharp edges, or used on rough surfaces. Use controlled strokes, avoid scrubbing, and switch to foam/knit polyester when fiber control is critical.

STX705P is a long-reach sterile cotton swab sized for general sterile-area work: long enough to keep hands back, with a cotton head that favors pickup and transfer. The key decision is not the millimeters—it is whether your surface can tolerate cotton contact without unacceptable fiber or cosmetic risk.

The values below are manufacturer-reported analyses that represent production sampling, not specifications. In practice, treat them as a baseline for risk assessment and method development: they help you compare swab families, set reasonable acceptance criteria for incoming lots (when your QA program requires it), and select the right construction for your residue risk.

How to use this data: For residue-sensitive cleaning, NVR becomes the practical limiter—especially if you are wiping to “no visible streaks” under angled light. For sampling, ions and NVR matter because they can bias analytical baselines. If your method is validation-driven, define acceptance criteria in your protocol and verify incoming lots against your program needs.

• Unit packaging: 1 swab per peel-apart sleeve for point-of-use sterility.
• Inner packaging: 50 sleeves per inner bag; bags are triple-bagged to support clean introduction to sterile areas.
• Case quantity: 10 bags per case (500 swabs per case).
• Traceability: Lot coded; expiration date is marked on each sleeve for inventory control and investigations.
• Sterility: Gamma irradiated to SAL 10^-6, with manufacturer references to ANSI/AAMI/ISO 11137 and AAMI validation guidance.
• Shelf life: Sterile product shelf life is listed as 3 years from date of manufacture.
• Country-of-origin statement (manufacturer TDS): Sterile – Made in Philippines, Gamma-irradiated in the USA.

Packaging discipline matters because most real-world contamination is introduced during staging. Triple-bagging supports cleaner transfer, but it only works if the outer layers are treated as “dirty” and removed before entry.

The highest-yield improvements come from wetness control and stroke discipline. Most streaks, redeposits, and “mystery fibers” are technique problems, not product problems.

• Open/transfer discipline: If you are introducing into a sterile area, remove outer bags outside the critical zone. Inside, open the inner bag only as wide as needed, stage sleeves on a clean tray, and reseal/close promptly.
• Damp solvent technique: Aim for damp, not wet. If using IPA, wet the cotton head until it is uniformly damp, then touch once to a clean, solvent-compatible surface (or the inside of a solvent-wet wipe) to knock down excess. Avoid “flooding” because it creates tide marks and drags dissolved residue.
• No re-dipping: Do not re-dip a used swab into your solvent container. That practice contaminates the solvent and creates cross-contamination risk between parts and lots.
• Stroke count logic: Use single-direction strokes with overlap. For flat areas, use 3–5 controlled passes, rotating the head a quarter-turn between passes to present a cleaner surface. Stop when the head loads (visible discoloration, drag increases, or fibers begin to lift).
• Geometry control: For tracks, slots, and channels, use the long handle to keep a consistent approach angle. Keep gloves and sleeves out of the opening; do not “choke up” on the handle near the head.
• Pressure guidance: Use enough pressure to maintain full contact, not enough to abrade or scrub. Excess pressure increases fiber release and smears residues into corners.
• Solvent compatibility: IPA is common; acetone may be used for some applications per manufacturer references, but always validate compatibility with plastics, paints, and coated surfaces. If your process is regulated, document the compatibility rationale in your method.
• Handling discipline: Once the sleeve is opened, avoid placing the swab down. If you must pause, discard and restart. Do not allow the cotton head to contact the outside of the sleeve or bag opening.
• Disposal and documentation: For investigations or QA-driven environments, capture lot code and expiration date from the sleeve in the batch record or deviation note. Discard as single-use; do not attempt to dry and reuse.
• Verification step: For critical cleaning, confirm with a defined endpoint: visual under angled light, swab-to-swab cleanliness trend, or analytical testing (TOC/ions) as required by your protocol.

If you consistently see fibers or streaks, do not “muscle through” with more strokes. Reduce wetness, reduce pressure, and switch to a foam or knit-polyester cleanroom swab family when the surface demands it.

• Fiber transfer on sensitive surfaces: Cotton can shed on sharp edges, rough finishes, or when overworked. This is a selection gate—move to foam or knit polyester for fiber-critical work.
• Streaks and tide marks: Caused by over-wetting, flooding, or stopping mid-stroke. Use damp technique, single-direction strokes, and defined stop conditions.
• Residue redeposit: Happens when the head is loaded and you keep working. Rotate the head and limit stroke counts; discard early.
• Cross-contamination: Re-dipping into solvent, setting a swab down, or touching “clean” areas after contacting a “dirty” area.
• Bond/solvent mismatch: Spun cotton swabs use a water-based adhesive bond by design. Validate aggressive solvent exposure and dwell time if your method is sensitive to extractables or adhesive interaction.

The closest alternatives are typically sterile medical specimen cotton swabs on polystyrene handles. Mechanically, they can look similar; the meaningful differences are program controls: published contamination characterization (ions/NVR), clean introduction packaging (triple-bagging), lot/expiration traceability, and documentation availability.

• Puritan 25-806 (sterile cotton swab, polystyrene handle): Similar cotton-on-polystyrene concept for sampling workflows. Evaluate whether contamination data, clean introduction packaging, and lot/expiration conventions match your controlled-environment requirements.
• Dukal-style sterile cotton-tipped applicators (6" class): Common in medical supply channels. Often adequate for general specimen tasks, but frequently lacks cleanroom-focused contamination characterization and multi-layer clean introduction packaging.
• Medline/Puritan catalog cotton swabs with polystyrene handles: Broad medical catalog options. Use when your risk assessment accepts medical-grade controls; for cleanroom and pharma-grade programs, verify documentation, lot traceability, and published cleanliness data before standardizing.

STX705P fits best where sterility, absorbency, and routine sampling discipline matter—and where the surface can tolerate cotton contact. It is commonly used in controlled environments that align with ISO cleanroom thinking (classification, gowning discipline, controlled introduction of materials) and regulated workflows where documentation, traceability, and method consistency are expected.

SOSCleanroom supports ITW Texwipe swab programs to reduce last-minute substitutions that break cleaning or sampling methods. That support shows up in practical ways: consistent stocking, fast shipping, responsive customer service, and straightforward access to manufacturer technical data sheets for audit readiness.

If your application is validation-driven (for example, documented sampling methods, residue limits, or trend investigations), use the published contamination metrics as baseline input and formalize acceptance criteria in your protocol. For environments governed by FDA expectations, ASTM test methods, or IEST contamination-control practices, “fit” is less about marketing and more about traceable, repeatable execution.
