Texwipe TX3343 TOC Cleaning Validation Kit for 12 Samples (Includes TX761K Low TOC Long-Handle Snap Swabs)

Texwipe TX3343 is a Total Organic Carbon (TOC) cleaning validation kit engineered to reduce sampling-driven variability by controlling the consumables that most often contaminate TOC results: low-TOC swabs, low-TOC vials/caps, and cleanroom-compatible handling and packaging. Each kit is built for surface sampling across 12 defined sampling areas and is lot coded for traceability and quality control. TX3343 includes TX761K Low TOC Alpha® long-handle SnapSwabs (certified <50 µg/L, <50 ppb) and prewashed 40 mL vials (certified <10 µg/L, <10 ppb) so your blank and background contribution stays predictable when your technique is consistent. The notched, break-away swab handle is designed to drop the swab head into the vial with minimal handling—a practical control point when teams are trying to prevent false positives, reduce investigation churn, and keep TOC data defensible.

Texwipe (an ITW company) is a worldwide leader in contamination-control consumables and critical cleanroom supplies. In cleaning validation sampling, Texwipe differentiates by treating the sampling step as a controlled system: engineered swab constructions, certified low-background components (swabs and vials), lot traceability, and cleanroom-compatible packaging intended to reduce the chances that handling or background carbon becomes the limiting factor in TOC data quality.

SOSCleanroom (SOS) supports validated programs with continuity of supply, clean documentation handoff, and practical application guidance—so your TOC sampling kit stays consistent across lots and replenishment cycles without unqualified substitutions that can introduce variability.

• Organized, convenient, and secure method for transporting swabs and vials from storage to sampling sites to the laboratory with minimal chance of contamination
• Certified low-TOC swab background contribution: <50 µg/L (<50 ppb)
• Certified low-TOC vial background contribution: <10 µg/L (<10 ppb)
• TX761K double layered, double knit polyester head designed to capture residue and release into diluent for recovery
• Notched, break-away SnapSwab handle enables head transfer into vial with minimal handling and reduced contact risk
• 100% polypropylene swab handle provides strong chemical resistance and helps avoid introducing additional contaminants
• Prewashed 40 mL vials with bonded septa caps; one-piece cap/septa design for straightforward sampling and analysis
• Polyethylene overcap protects septum surface until analysis; sloped shoulder design minimizes headspace for reduced background
• Cleanroom compatible vial labels support sample identification and traceability
• Double-bagged kit components packaged in a cleanroom-compatible polypropylene box
• Lot coded for traceability and quality control

• Reduces sampling-driven false positives: Certified low-background swabs and vials help prevent the consumables from dominating your TOC signal (method-dependent)
• Improves repeatability across operators: Kit format standardizes components and supports disciplined, consistent technique in routine monitoring and investigations
• Cleaner chain-of-custody: Lot coding and cleanroom-compatible labels simplify traceability, trending, and investigation documentation
• Less handling risk: Break-away handle design supports head transfer into the vial with minimal handling and less opportunity for incidental contamination
• Operational efficiency: Preconfigured kit reduces time spent staging and assembling mixed components, especially when sampling is performed across multiple locations or shifts

• Surface sampling for TOC analysis as part of a cleaning validation protocol
• Surface sampling as part of other cleaning validation protocols where low-background consumables are required
• Non-organic liquids sampling for contamination source investigations (method-defined)
• Pharmaceutical, biologics, and medical device manufacturing cleaning validation workflows where sampling discipline must stand up to audit review

• Define the sampling area: Standardize the surface area, location, stroke count, and pressure so recovery is comparable across operators and time.
• Control wetting: Dampen the swab with the method-defined diluent (do not flood). Over-wetting can spread residue and change recovery.
• Use a disciplined wipe pattern: Apply unidirectional, parallel strokes; then rotate to a perpendicular direction to improve coverage (as defined by your written procedure).
• Prevent handling contamination: Do not touch the handle below the notch line; avoid contacting gloves, benches, vial exteriors, or caps with the swab head.
• Transfer correctly: Remove vial cap, snap the swab head at the notch along the vial edge so the head drops into the vial, then recap immediately.
• Label and secure: Use the included cleanroom-compatible labels, document the lot code as required by your protocol, and transfer to the lab under your chain-of-custody controls.
• Standards and regulatory awareness: Align your validation posture and sampling controls to your quality system expectations (FDA: https://www.fda.gov; ISO: https://www.iso.org/standard/53394.html; ASTM: https://www.astm.org; IEST: https://www.iest.org).

• Why a kit matters: In TOC validation, a clean swab does not rescue a contaminated vial/cap pathway. TX3343 is built as an integrated system to reduce background and handling variability.
• Long-handle access: TX3343 includes TX761K long-handle low-TOC swabs for reach into tighter geometries and deeper equipment features where gloved hands and short handles increase contact risk.
• Method fit first: Confirm your diluent choice, recovery expectations, acceptance criteria, and analyst workflow before standardizing. The kit controls the consumables, but the method still drives defensibility.
• Investigation readiness: When a trend shift triggers CAPA or batch impact decisions, lot coding and controlled packaging help simplify root-cause questions tied to consumables and handling.
