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.
