Key Features of Nylon Flocked Swabs:

1. Unique Design

• The swab head is made of short nylon fibers (flocked) arranged vertically, resembling a brush-like surface.
• Unlike traditional wound fiber swabs (e.g., cotton or polyester), flocked swabs have no internal absorbent core, allowing for better sample release.

1. Superior Sample Collection & Release

• No absorption trap: Liquid samples stay on the surface, improving recovery rates (critical for cleaning validation in pharma).
• Minimal sample retention: Ideal for HPLC, LC-MS, and microbial testing where residue interference must be avoided.

1. High Purity & Low Particle Shedding

• Made from medical-grade nylon, ensuring low contamination risk.
• Suitable for cleanroom environments (ISO Class 5+) and sensitive lab applications.

1. Flexible & Non-Abrasive

• The soft flocked tips prevent surface damage, making them ideal for delicate equipment, electronics, and medical devices.

1. Compatibility with Harsh Solvents

• Resistant to alcohols, acetone, and most cleaning agents used in pharmaceutical validation.

Common Uses of Nylon Flocked Swabs:

✔ Pharma/Cleaning Validation** – Detecting residues on equipment (GMP/GLP compliance).
✔ Medical/Diagnostics – DNA/RNA collection (e.g., COVID-19 tests, forensic sampling).
✔ Electronics – Precision cleaning of circuit boards and optical components.
✔ Microbiology – Surface monitoring in labs and cleanrooms.
