CONSTIX® SC-3 double-ended round cotton swabs consist of high-quality, long staple-length cotton, tightly wrapped and shaped on both ends of high strength, wound paper handles. The heads are held to the handles using a methyl-cellulose binder.

• Absorbent cotton head is ideal for use with aqueous based solutions
• Tightly wrapped head help maintain low levels of extractable residue

The high-quality cotton fibers provide excellent particle entrapment and retention, as well as exceptional sorbency of most solvents and solutions. The heads are very tightly wrapped and shaped using a methyl-cellulose binder which minimizes fiber shedding. The SC series cotton swabs are absorbent to most common solvents including isopropyl alcohol, acetone, and aqueous solutions.
