Coventry™ Swabs and Wipes: From Our Cleanroom to Yours

At Coventry™, we understand exactly what you want from your cleaning products:

Reliability and Performance. Coventry products keep contamination out of your process, improve yield, and perform consistently, shipment to shipment.

Cleanroom Quality and Consistency. To manufacture a Coventry swab, we start with engineered clean materials. Polyester swab and wipe components are laundered first in our Class 10 (ISO Class 4) cleanroom.

Exclusive Post-Manufacturing Processes. Coventry’s Aqua-Prime™ process reduces particles, ionic contamination, and non-volatile residue. The Aqua-Prime™ process cleans the swab with a purified proprietary solvent blend. 

Widest Selection of Critical Application Swabs. Coventry has a wide variety of choices to meet your most demanding applications. The wrapped swab, uniquely designed with no seams or edges, prevents scratching of delicate surfaces. Also included in the product line are sealed fabric, sealed foam, and static control. All Coventry products are packaged in non-contaminating ESD safe plastic bags. You’re sure to find a swab from Coventry that meets your particular need.

Products That Bring Value, not Contamination, to Your Processes. Strict quality controls throughout ensure consistent reliability. Clean and static-free packaging seals in contamination-free quality from our cleanroom to yours.

Dedicated Customer Support. Live support is available via our Technical Hotline at 1-800-TECH-401. We even custom engineer products for your special needs.

FAQ's

Are swabs available for cleaning static sensitive electronics?

Yes, Chemtronics offers a full line of ESD swabs. They include foam, knit polyester, or knit microfiber heads with static dissipative handles. The proprietary handle material has surface resistivity of 1.0 x 10_10 ohms/sq, and will dissipate 99% of (5 kV) charge in 0.5 seconds. This avoids static generation, and can dissipate a charge when the user is grounded.

Are Q-tips / cotton bud swabs lint free?

No, cotton bud swabs (aka Q-tips) can’t be considered lint-free. Cotton tends to lead behind threads and particulates. Open cell polyurethane foam swabs are a common, very clean replacement for cotton. If harsh solvents are being used on the swabs, or even more cleanliness is needed, knit polyester or microfiber swabs are an excellent choice.

What is a foam swab? / Why should I use a foam swab?

While cotton bud swabs (aka Q-tips) are commonly used for all kinds of precision cleaning, foam swabs are commonly used to reduce contamination from cotton threads and particulates. Foam swabs are usually made of open cell polyurethane for maximum cleanliness and absorbency. Foam swabs are usually made of open cell polyurethane for maximum cleanliness and absorbency.

What is a sterile swab?

Sterile swabs are free from bacteria or other living microorganisms. Common methods for sterilization include autoclaves, ETO (ethylene oxide gas), and Gamma irradiation. Sterile swabs are generally used for biological sample collection to avoid sample contamination, and for medical use to avoid infection.
