TX716 Large Absorbond HPLC Sampling Polyester Cleanroom Swab

Texwipe TX716 is a cleanroom-processed, low-linting (no swab is truly ‘lint-free’ in every process condition) Absorbond® polyester nonwoven sampling swab engineered for cleaning validation and solvent-based critical cleaning. The double-layer, hydro-entangled polyester head is designed to entrap residue during sampling while supporting release into the diluent for strong recovery performance—a key requirement when HPLC results must be defensible. TX716 uses a complete thermal-bond construction (no adhesive) and a rigid 100% virgin polypropylene handle for chemical resistance, repeatable handling, and lot-coded traceability in regulated and controlled environments.

• Typical use environments: Controlled areas and ISO-class cleanrooms where sampling consistency, documentation, and contamination control matter (final suitability depends on your SOP and validation strategy)

Texwipe (an ITW company) differentiates itself in cleanroom swabs by treating the swab as an engineered sampling and cleaning tool—not a commodity. That approach emphasizes controlled material selection, tight dimensional tolerances, cleanroom processing, and construction choices (such as thermal bonding to eliminate adhesive variables) that help teams standardize results across operators and lots.

For cleaning validation and critical cleaning programs, Texwipe also emphasizes lot traceability and contamination controls intended to support repeatability in the lab and on the floor. SOSCleanroom (SOS) supports that discipline with a close working relationship with Texwipe focused on continuity of supply, clean documentation handoff (certs, lot traceability), and practical application support—so validated methods are less likely to be disrupted by last-minute substitutions.

• Double-layer hydro-entangled polyester nonwoven head for enhanced absorbency and residue capture
• Designed to entrap contaminants during sampling while supporting release into the diluent for strong recovery rates
• Complete thermal-bond construction (no adhesive) to reduce extractables risk and improve solvent compatibility
• Excellent chemical resistance for compatibility with a wide range of cleanroom solutions and solvents (verify to your chemistry and method)
• Cleanroom processed for ultra-low levels of particles, NVRs (non-volatile residues), and ions (typical values; validate to your method needs)
• Rigid 100% virgin polypropylene handle helps reduce introduced contaminants and supports controlled handling
• Lot coded for traceability and quality control
• Packaged in a silicone-free and amide-free bag to help reduce background variables
• Autoclave safe in dry heat and steam (qualification recommended)

• Defensible HPLC sampling performance: Built for cleaning validation workflows where recovery, release into the diluent, and consistent technique drive data quality.
• Reduced construction variables: No-adhesive thermal bond helps remove a common source of extractables and bond-line variability when alcohols or mixed solvents are used.
• Controlled cleanliness for low background: Typical low particles, ions, and NVR support lower method noise and cleaner blanks (process- and method-dependent).
• Repeatable handling: Flat paddle geometry supports defined-area strokes and consistent coverage during surface sampling.
• Process compatibility: Chemical resistance and cleanroom processing support use across pharmaceutical, biotech, semiconductor, microelectronics, and optics controlled environments.

• Cleaning validation surface sampling for pharmaceutical and biotech equipment (HPLC / related analytical approaches)
• Solvent-based critical cleaning (such as IPA) where controlled application and removal matters
• Cleaning sensitive surfaces such as optical assemblies
• Cleaning grooves, tracks, slots, and other small spaces where a flat paddle head improves contact control
• Controlled spot cleaning in microelectronics, semiconductor, and precision assembly environments

• Treat it like a measurement tool: For cleaning validation, the goal is consistent residue collection and release into the diluent—avoid improvising technique between operators.
• Control the area: Use a template or defined sampling area when required by your protocol; keep stroke count and overlap consistent.
• Use straight-line, overlapping strokes: Maintain the swab face flat to the surface; avoid rolling the head, which can change contact pressure and coverage.
• Solvent-fit matters: TX716 is commonly used with solvents other than water—confirm wetting and extraction conditions during recovery studies.
• Change-out discipline: If the head becomes overloaded or you observe streaking/residue transfer, replace the swab per SOP to avoid re-deposition.

• Nonwoven vs. knit heads: Choose Absorbond® nonwoven when your method benefits from hydro-entangled structure designed for capture and release into the diluent; evaluate knit-based sampling swabs when your protocol specifies alternative head architectures.
• Solvent reality: If your recovery study and extraction solvent are primarily aqueous, validate wetting and extraction carefully; TX716 is commonly described as most effective with solvents other than water.
• Geometry control: The flat paddle head supports defined-area sampling and consistent edge-to-edge contact—useful when repeatability and defensible technique are priorities.
