Cotton Twine is a versatile filament made from twisted strands of natural cotton fibers. It is soft yet durable, offering flexibility and strength for binding, tying, or securing items in both laboratory and industrial environments. Cotton twine is non-abrasive, lint-minimal, and chemically inert to most laboratory reagents, making it suitable for specimen tying, light bundling, or general-purpose securing within controlled settings.
Cotton twine
Primary Uses
