Frequently Asked Questions

What cleanroom class is the LTP125.5 rated for?
The LTP125.5 is rated for ISO Class 3 (Class 1) through ISO Class 5 (Class 100) cleanrooms. It is suitable for semiconductor fabrication, pharmaceutical manufacturing, medical device assembly, and electronics manufacturing environments requiring controlled contamination levels.

What is the paddle head design and why does it matter?
The LTP125 features a flat paddle head with a rigid internal polypropylene support structure. The flat paddle geometry maximizes contact surface area per swipe compared to a round or pointed tip, making it more efficient for cleaning flat surfaces, wiping large areas, and surface sampling applications where coverage per stroke matters.

Are LTP125.5 swabs compatible with IPA and other solvents?
Yes — the continuous filament polyester knit head has excellent chemical resistance and is compatible with isopropyl alcohol (IPA) and most organic solvents commonly used in precision cleaning and surface preparation. Always verify compatibility with your specific cleaning agent before use in critical applications.

How are the swabs packaged for cleanroom use?
LTP125.5 swabs are supplied 100 per pack, 5 packs per case (500 total). The pack format allows individual packs to be introduced into a cleanroom airlock or pass-through without opening the full case, minimizing contamination risk during gowning and material transfer.
