Coventry Wrapped Foam Swabs

Our wrapped foam swabs provide good particle entrapment and work very well as adhesive, lubricant and solvent applicators. With the most durable head of any foam swabs, wrapped foam delivers superior abrasion resistance for removal of tough contaminants. Wicking action pulls solvent from surfaces. The small tips on some of the styles allow use in very tight tolerance areas, while the pointed ends work especially well as picks.



Features & Benefits

  • Excellent wicking pulls solvent away from surfaces
  • Stronger head than other foam swabs
  • Fiberless construction does not generate loose fibers or particles
  • No adhesives or binders are used in the construction
  • Excellent abrasion resistance for scrubbing rough surfaces


  • Apply Adhesives or Lubricants into Tight Tolerance Areas
  • Splice and Assembly of Fiber Optics
  • Dispense or Remove Solvents
  • Remove Contamination from Disk Drives
  • Scrub Metal Oxides from Electrical Contacts

What are the different types of cleanroom swabs?

Cleanroom swabs are essential tools used in controlled environments, such as cleanrooms, where maintaining high levels of cleanliness and avoiding contamination is crucial. Different types of cleanroom swabs are designed to meet specific requirements and are made from various materials to suit different applications. Some common types of cleanroom swabs include:

  • Foam Swabs: Foam swabs are made from polyurethane foam, which has excellent solvent compatibility and high absorbency. These swabs are ideal for cleaning delicate surfaces, applying solvents, and removing excess residues. Foam swabs come in different sizes and shapes to address various cleaning needs.
  • Polyester Swabs: Polyester swabs are constructed from a synthetic material that has low particle generation and good chemical resistance. These swabs are often used in precision cleaning applications, particularly in sensitive electronic components and hard-to-reach areas.
  • Microfiber Swabs: Microfiber swabs are designed to trap and remove microscopic particles effectively. They are often used in cleaning sensitive optical surfaces, camera lenses, and other high-precision equipment.
  • Cotton Swabs: Cotton swabs, also known as cotton-tipped swabs, have a cotton tip attached to a plastic or wooden handle. They are commonly used in less critical cleanroom environments for general cleaning and application of solutions.
  • ESD-Safe Swabs: Electrostatic discharge (ESD)-safe swabs are designed to prevent damage to sensitive electronic components that could be harmed by static electricity. These swabs are usually constructed with conductive materials that dissipate static charges.

It's important to select the right type of cleanroom swab based on the specific needs of the cleanroom environment and the surfaces or equipment being cleaned. Each type of swab has unique characteristics that make it suitable for different applications, so proper selection is essential to ensure effective cleaning and avoid any risk of contamination.

What is a cleanroom swab?

A cleanroom swab is a specialized cleaning tool used in controlled environments such as cleanrooms, laboratories, and manufacturing facilities where maintaining a high level of cleanliness and eliminating contaminants is essential. Cleanrooms are environments with low levels of airborne particles and other pollutants to ensure the integrity of sensitive processes, products, or experiments.

Cleanroom swabs are designed to be non-shedding, low in particle generation, and non-reactive, so they do not introduce contaminants or interfere with the materials being processed or tested. They come in various shapes and sizes, typically with a handle or shaft made of materials like plastic, wood, or metal, and a head made from materials like foam, polyester, or microfiber.

The choice of swab material and construction depends on the specific cleaning requirements and the type of surface or equipment being cleaned. Some cleanroom swabs are pre-saturated with isopropyl alcohol or other cleaning agents to aid in removing residues and contaminants.

Cleanroom swabs play a critical role in various industries, including semiconductor manufacturing, pharmaceuticals, biotechnology, aerospace, and medical devices, where even tiny particles or contaminants can cause significant defects or compromise product quality. Proper cleaning and maintenance of cleanrooms and equipment are vital to ensure consistent and reliable performance in these industries.
