Product Description
Texwipe TX5740 TexWrite® Cleanroom Spiral Notebook — 8.5" x 11", White, College-Ruled
TX5740 is a spiral-bound cleanroom notebook for technician note-taking, batch/lot recording, equipment logs, and controlled-environment data capture. It uses TexWrite® 22 cleanroom bond pages printed with IPA-resistant, low-sodium ink to help reduce ionic contamination risk during routine documentation.
For over 35 years, SOS and Texwipe have been close partners, and SOSCleanroom is the authorized Master Distributor of ITW Texwipe for the United States market. That relationship matters when you are standardizing cleanroom stationery: it supports continuity of supply, stable product lineage, and fast access to the manufacturer documentation your QA/QC team expects.

Low particle and fiber generation — and the reality check
This notebook is designed for ultraclean handling with low particle and fiber generation. Even so, no paper product is truly “lint-free.” Treat stationery like a contamination-controlled component: control when it is opened, how it is transported, and what touches the pages.
Practical cleanroom use guidance (technicians and engineers)
- Open/close discipline: Open slowly and keep it closed when not in use to reduce “air pumping” that can mobilize particles.
- Segregate the work zone: Keep the notebook off critical surfaces; do not lay open pages on benches where residues or particles can transfer.
- Glove control: Avoid wet gloves and solvent-wet fingertips. Solvent on gloves is one of the fastest ways to create smearing, transfer, and page edge degradation.
- Page handling: Minimize aggressive page flipping near product or open assemblies. Rotate pages deliberately and avoid dragging sleeves across the writing area.
Compatibility and wipe-down notes
- IPA exposure: Pages are printed with IPA-resistant ink, and the HDPE cover is a chemical-resistant material. If your SOP permits, this supports typical external wipe-down practices.
- Do not autoclave: Autoclaving is not recommended for this notebook. Use sterile documentation products that are explicitly rated for autoclave cycles when required by the program.
- DI water / aqueous wipe-down: Not published for this notebook. If your site requires aqueous wipe-down, qualify the notebook under your conditions before standardizing.
- Wipe-down technique: Wipe the closed cover first, avoid saturating page edges, and allow full dry time before opening to reduce ink transfer and residue.
Typical performance characteristics
Features- Smearing / ink transfer: Usually from solvent contact before dry time, wet gloves, or closing pages too quickly. Prevent with dry-time discipline and glove moisture control.
- Paper dusting / abrasion: Triggered by high writing pressure, scraping tools, or aggressive erasing. Prevent with controlled writing pressure and SOP correction practices (strike-through/initial if applicable).
- Residue carryover: Transfer from benches, sleeves, or contaminated gloves. Prevent by keeping pages off work surfaces and maintaining “documentation-only” handling.
- Static attraction: In low humidity, stationery can attract fines. Prevent by following site ESD controls and avoiding rubbing covers against garments.
