Description

Lightweight polyester cleanroom wipers are designed for precise cleaning in controlled environments. They help remove particles while reducing the risk of contamination.

Each wiper is made from 100% continuous filament polyester. This material produces very low lint and helps limit particle release. It is a reliable choice for ISO Class 5 cleanrooms and other critical applications.

The soft, non-abrasive surface is safe for delicate equipment and sensitive components. These wipers clean effectively without scratching or damaging surfaces.

Despite their lightweight feel, they are strong and durable. They also work well with a wide range of solvents and cleaning solutions.

These wipers are commonly used in cleanrooms, labs, and electronics manufacturing where precision cleaning is essential.

Key Features

• Rated for ISO Class 5 cleanroom environments
• Made from 100% continuous filament no-run interlock knit polyester for extremely low lint performance
• Laser cut edges seal fibers at the wiper’s perimeter, preventing fraying and particle release
• Cleanroom laundered before packaging to ensure cleanliness at the point of use
• Low in both particles and extractables for use in the most contamination-sensitive applications
• Non-abrasive surface safe for delicate equipment, optics, and sensitive components
• Abrasion and chemical resistant with good sorbency for use with a wide range of solvents
• Available in two sizes: 9″ x 9″ and 12″ x 12″
• Packaged 150 wipers per bag, 15 bags per case (2,250 wipers per case)

 
Common Uses

• Surface cleaning in ISO Class 5 and stricter cleanroom environments
• Semiconductor wafer fabrication and equipment wiping
• Optical component and lens cleaning
• Pharmaceutical manufacturing surface preparation and validation
• Medical device assembly and precision cleaning
• Electronics and circuit board manufacturing
• Applying and removing solvents and cleaning agents on critical surfaces
• Cleanroom equipment and workstation maintenance

 
Who This Is For

These wipers are designed for cleanroom professionals, lab technicians, and process engineers working in environments where standard wipers simply are not clean enough. The ISO Class 5 rating, laser cut sealed edges, and cleanroom laundering make them appropriate for semiconductor, optical, and pharmaceutical applications where particle counts and extractable levels are tightly controlled. The 12″ x 12″ size works well for larger surface areas and equipment wiping, while the 9″ x 9″ size offers more precision for smaller components and tight workspaces. If your operation requires a wiper you can trust at the highest levels of cleanliness, this is a reliable choice.

FAQ

What does ISO Class 5 mean for a cleanroom wiper?
ISO Class 5 is a cleanroom classification that specifies very low allowable particle counts in the environment. A wiper rated for ISO Class 5 is manufactured, laundered, and packaged under conditions that meet those strict particle control standards, making it suitable for use in similarly classified environments.

Why are the edges laser cut instead of stitched or hemmed?
Laser cutting seals the polyester fibers at the wiper’s edge as it cuts, eliminating the loose threads and fraying that stitched or hemmed edges can produce. This significantly reduces particle generation, which is critical in high-specification cleanroom applications.

Are these wipers compatible with solvents?
Yes. These wipers are abrasion and chemical resistant with good sorbency for use with a wide range of solvents and cleanroom-approved cleaning agents. Always verify compatibility with your specific chemical before use.

What is the difference between the 9″ x 9″ and 12″ x 12″ sizes?
The 9″ x 9″ wiper is better suited for precision cleaning of smaller components, tight workspaces, and detailed surface work. The 12″ x 12″ wiper covers more surface area and is a better fit for wiping down equipment, workstations, and larger surfaces.

Are these wipers cleanroom laundered?
Yes. These wipers are cleanroom laundered before packaging, which removes particles and residues introduced during manufacturing and ensures they arrive ready for use in controlled environments.

How many wipers come per case?
Each bag contains 150 wipers and each case contains 15 bags, for a total of 2,250 wipers per case.

Can these wipers be used dry or do they need to be pre-wetted?
These wipers can be used both dry and wetted with an appropriate solvent or cleaning solution, depending on the application and the type of surface or residue being addressed.

How do these compare to the foam wipers also available in this store?
Polyester knit wipers like these offer excellent particle control and chemical compatibility, making them a strong choice for critical surface wiping and solvent application. Foam wipers tend to offer higher fluid absorption and are often preferred for applying and removing larger volumes of cleaning solution. The best choice depends on your specific application requirements.
