Texwipe TX5835 TexWrite 9" x 13" Cleanroom Clipboard

Shown: Texwipe TX5835 TexWrite® Cleanroom Clipboard.

Clipboards are deceptively high-risk in controlled areas because they travel everywhere: gowning benches, airlocks, aisles, staging racks, and process bays. When a clipboard is treated like ordinary office gear, it becomes a roaming “contact surface” that can pick up particles and residue, then reintroduce them where people write, verify, and sign. TX5835 is intended as a portable writing surface that supports critical-environment documentation without sharp edges that snag gloves or garments, and without improvised, hard-to-clean clipboards entering the room.

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 partnership matters for document-control stationery because audits often hinge on consistency: the same product, the same packaging configuration, and the same published technical support every time the material is re-ordered.

• Note taking, data transfer, and recording inside controlled areas (manufacturer-stated).
• Forms and production tracking where operators must write while standing or moving (manufacturer-stated).
• Holding 8.5" x 11" or A4 cleanroom paper for checks, sign-offs, line clearance, and equipment status sheets (manufacturer-stated).
• Portable point-of-use documentation when benches are occupied or when paper stacks should stay in controlled storage.

• Cleanroom-intended handling profile: rounded corners and “no sharp edges” are specifically called out to avoid glove/garment damage (manufacturer-stated).
• Chemical compatibility intent: manufacturer literature describes compatibility with common cleanroom chemicals and chemical-resistant construction (manufacturer-stated).
• Paper control: securely holds 1–50 sheets so pages do not slide onto benches, carts, or floors (manufacturer-stated).
• Controlled introduction: cleanroom packaged to support disciplined transfer into critical environments (manufacturer-stated).
• System fit: designed to pair with TexWrite® documentation materials so clipboard + paper behave as a single, repeatable document-control pathway.

TX5835 is described by the manufacturer as a rigid plastic clipboard with a durable plastic clip mechanism. One important procurement note: published sources are not fully consistent on the exact plastic type. Texwipe’s current technical data sheet (Rev.03-10/22) lists rigid polystyrene, while the SOSCleanroom product page and an older Texwipe datasheet (Effective: December 2009) list rigid polypropylene. If your facility has specific polymer restrictions (extractables, chemical exposure, or autoclave proximity), confirm the material with the manufacturer documentation tied to your purchase order.

Build features that matter on the floor include: rounded corners (reduces snagging and tears), a rigid back (writing while standing), and a clip area that is robust enough to avoid flexing and page slip. Most clipboard-related contamination issues originate around the clip mechanism (crevices, repeated touch points), so material and geometry both matter.

Stationery failures in critical environments tend to look like particles, residue, and handling transfer rather than an obvious “clipboard problem.” The clip mechanism area is the usual hot spot: repeated finger contact, crevices, and the leading edge that touches paper stacks. Manufacturer guidance emphasizes chemical compatibility and cleanroom packaging, which supports a controlled introduction and wipe-down strategy.

What is not published in the cited sources: extractables data, outgassing data, surface finish roughness, or validated compatibility against specific disinfectants (IPA, ethanol, quats, sporicides). If your clipboard is routinely wiped as part of room cleaning, qualify your wipe chemistry and contact time against the clipboard surface and clip mechanism so you do not create brittleness, stress cracking, or sticky residue that later sheds onto gloves.

• Pack configuration: 12 clipboards/box (manufacturer-stated); SOSCleanroom case unit is 12 clipboards per case.
• Packaging condition: cleanroom packaged (manufacturer-stated).
• Sterility: not stated in source basis.
• Traceability practice tip: if clipboards are used in GMP/regulated documentation zones, treat them as controlled reusable tools (issue/return, cleaning status, and replacement criteria). Capture the product identifier during receiving so replacements stay consistent.
• Country of origin: Made in USA (manufacturer-stated in Rev.03-10/22 technical data sheet).

• Assign ownership: treat clipboards like tools. Issue them to a room, a line, or a process family rather than letting them roam between uncontrolled and controlled spaces.
• Wipe-down method: wipe the flat writing surface and pay extra attention to the clip underside and leading edge. Avoid flooding the clip mechanism with liquid; pooled chemistry can leave residue and create sticky “particle traps.”
• Paper discipline: load only what is needed for the task. A thick stack increases rubbing and edge wear, and it encourages operators to “fan” sheets, which spreads debris.
• Document-control flow: if the clipboard carries a traveler/batch packet, define where it can rest (dedicated hooks or a clean staging surface). Avoid placing it on carts that also hold waste, dirty tools, or outer packaging.
• Inspection cue: include clip tension and surface integrity in a simple periodic check. A weakened clip causes dropped pages and uncontrolled contact events that become investigation time sinks.

• Residue buildup around the clip: repeated wipe-downs with strong chemistries can leave films that collect particles. If residue forms, revise wipe chemistry or add a rinse/wipe step per your internal methods.
• Clip wear or loss of tension: pages slip, touch unintended surfaces, or fall. This is a documentation-control risk and a contamination-control risk.
• Surface scratching: scratched plastic can become harder to clean and can hold fine debris. Avoid abrasive pads; use compatible low-linting wipes and a validated chemistry.
• Stress cracking from chemistry mismatch: not published as resistant to specific solvents/disinfectants in the source basis; qualify your site chemistry and contact time.
• Cross-area migration: a clipboard used in one zone and carried into another can undermine line clearance. Fix with labeling, hooks, and ownership rules.

For clipboards in controlled environments, the most meaningful comparisons are: cleanroom packaging discipline, rounded/no-sharp-edge handling features, published environment guidance, and polymer compatibility with your cleaning chemistry.

• Berkshire cleanroom clipboards (compare packaging configuration and published cleanroom guidance for the exact part number).
• Valutek cleanroom clipboards (compare polymer construction and chemical compatibility statements for the exact part number).
• Contec cleanroom documentation accessories (compare design features around clip crevices, wipe-down guidance, and packaging discipline).

Texwipe states cleanroom environment guidance of ISO Class 3–8 (also expressed as Class 1–100,000 and EU Grade A–D). This aligns with many critical areas where documentation is handled at benches, carts, and equipment stations and must stay legible and controlled without introducing sharp-edge damage or uncontrolled debris.

Fit decisions are usually driven by workflow: if the clipboard will repeatedly cross airlocks or be wiped frequently, prioritize a documented cleaning/inspection routine and define where it may travel. For highest-sensitivity zones, the clipboard should be staged so it does not hover over exposed critical surfaces while pages are turned or signatures are captured.
