Unitek CRP0770-8GR Clean-Write® Cleanroom Spiral Notebook — 8.5" x 11", White, Grid Paper
CRP0770-8GR is a side-spiral cleanroom notebook for technician note-taking, equipment logs, calibration/PM records, deviation notes, and controlled-environment data capture where particle-shedding control and handling discipline matter. It is cleanroom packaged and built with semi-transparent, high-density polyethylene covers, a spiral binding that lays flat, and low-sodium inks to support low ionic contamination risk during routine documentation.
Use grid paper for layout-sensitive entries (fixture maps, tool offsets, layout checks, sample location grids, and line-by-line sign-offs) without bringing standard office notebooks into the controlled area.

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 particle-free or fiber-free in real operations. 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 fines.
- 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. Moisture and solvents accelerate smearing, transfer, and page-edge degradation.
- Page handling: Flip pages deliberately and minimize rapid page fanning near product or open assemblies. Avoid dragging sleeves across the writing area.
- Dedicated-use logic: Keep one notebook per toolset/line/room where feasible. This reduces cross-area particle and residue transport and supports investigations.
Compatibility and wipe-down notes
- Cover wipe-down: The cover is described as a chemical-resistant material. If your SOP permits wipe-down introduction, wipe the closed notebook first, avoid saturating page edges, and allow full dry time before opening.
- IPA / disinfectant tolerance (pages and ink): Not published for CRP0770 notebooks. If your process requires routine solvent contact, qualify the notebook under your site chemicals and dry-time rules before standardizing.
- DI water / aqueous wipe-down: Not published. Qualify under your conditions if aqueous wipe-down is required.
- Do not saturate the spiral or page edges: Wicking at edges is a common driver for residue, smearing, and particle release.

Common failure modes
- Smearing / ink transfer: Usually driven by wet gloves, solvent contact, or closing pages before dry time. Prevent with glove moisture control and dry-time discipline.
- Paper dusting / abrasion: Triggered by excessive writing pressure, scraping tools, or aggressive correction practices. Prevent with controlled writing pressure and SOP-correct error correction (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 cover rubbing against garments.
- Spiral snag / cover scuffing: Caused by abrasive stacking and rough transport. Prevent with clean pouches/drawers and avoiding contact with metal clips and tools.
Storage and handling best practices
- Keep notebooks in original cleanroom packaging until introduced into the controlled area.
- Store closed to reduce particle deposition on pages; transport in a clean pouch or drawer when possible.
- Avoid stacking with abrasive tools, clips, or metal hardware that can scuff covers and generate debris.
- Control exposure to wet chemicals; do not allow page edges or the spiral to wick solvent.
