STX705P Sterile Cotton Swab with Polystyrene Handle (Individually Wrapped, Gamma Irradiated SAL 10^-6)

Texwipe STX705P is an individually wrapped sterile cotton cleanroom swab built for sampling and controlled cleaning steps where teams need sterility at point-of-use, documentation discipline, and consistent geometry. The swab head is constructed from 100% USP-grade cotton and is bonded to a long polystyrene shaft using an aqueous-based adhesive. STX705P is gamma irradiated to a 10^-6 Sterility Assurance Level (SAL) in accordance with ANSI/AAMI/ISO 11137, and each swab is presented in easy-open, clear packaging so operators can visually confirm seal integrity before introduction into controlled workflows. In practical use, cotton provides strong absorbency and “grab” for particulate pickup and localized solvent cleaning (no swab is truly “lint-free” in every process condition; use technique control and early change-outs to keep fiber risk bounded to your validated method).

Texwipe (an ITW company) designs sterile swabs as controlled process tools, not commodity accessories. For STX705P, the value is operational: repeatable geometry, individually wrapped sterile presentation, visible seal integrity, and case-level documentation (irradiation and compliance) that supports traceability-driven programs in pharmaceuticals, biologics, medical device, microbiological labs, and diagnostic testing workflows.

SOSCleanroom (SOS) supports that manufacturing discipline with continuity of supply, documentation-forward order handling, and practical application guidance—so teams can standardize sterile cotton sampling and cleaning steps without last-minute substitutions that disrupt method consistency.

• Gamma irradiated to a Sterility Assurance Level (SAL) of 10^-6 in accordance with ANSI/AAMI/ISO 11137
• Individually wrapped, easy-open sterile sleeves help preserve point-of-use sterility
• Clear packaging supports visual confirmation of seal integrity
• Lot code and expiration date clearly marked on each package and included in barcode for inventory control
• Certificates of Irradiation and Compliance attached to each case confirm irradiation dose met specifications
• Pre-sterilized swabs eliminate repackaging, documentation, and validation of locally autoclaved swabs
• Packaging labeled for global use
• 100% USP-grade cotton head bonded to a long polystyrene handle for reach and control

• Sterile sampling you can defend: Individually wrapped sleeves plus lot/expiration markings support chain-of-custody expectations during investigations
• Absorbency for pickup and transfer: Cotton provides strong liquid hold and particulate pickup in many utility sampling/cleaning steps (method-dependent)
• Reach without improvisation: Long polystyrene handle supports access into ports, recesses, housings, and equipment corners
• Inventory and audit readiness: Barcode-embedded lot/expiration data plus case certificates support controlled issuance and recordkeeping
• Less local variability: Pre-sterilized presentation reduces on-site sterilization variability and reduces “repack” handling risk

• Diagnostic sampling
• Environmental monitoring
• Cleaning with solvents such as IPA (verify solvent compatibility to your SOP and avoid aggressive chemistries that can attack polystyrene)
• Spot sampling and pickup from recesses, ports, tubing ends, and equipment corners
• Routine sterile-area utility tasks where sterile point-of-use presentation is required

• Open-and-use discipline: Open the sleeve only when ready to sample/clean; avoid staging opened swabs to reduce handling-driven contamination risk.
• Technique control for cotton: Use light pressure, straight strokes, and early change-outs to reduce fiber risk; avoid dragging dry cotton on burrs or sharp edges.
• Define the method for sampling: Standardize stroke count, direction, and wetting approach so recovery is repeatable and defensible.
• No re-dipping into shared solvent: Re-dipping a used swab is a direct cross-contamination mechanism; use controlled dispense or single-use aliquots.
• Confirm solvent compatibility: If solvents are used, confirm handle compatibility and dwell time to avoid softening, stress cracking, or residue transfer.

• Choose STX705P when sterility + traceability are required: Individually wrapped sleeves, lot coding, and expiration dating support sterile workflows and documentation expectations.
• Cotton is a performance choice: Cotton excels at absorbency and particulate pickup, but it can retain analytes and can shed if misused—qualify recovery and fiber behavior to your method.
• Adhesive-bond reality: STX705P uses an aqueous-based adhesive; if your program is extremely sensitive to residue/extractables, consider qualifying an alternative swab family designed for lower background contribution.
• Handle length matters: The long polystyrene handle supports controlled reach into ports and recesses while keeping glove/finger contact away from the sample area.
