Bottle & Vial Caps

Rapid Labs offer a range of lined or wadded Polypropylene (PP) screw caps that are suitable for our selection of glass vials and bottles. Polypropylene caps are one of the most cost effective methods of sealing Screw-necked vials and bottles providing secure sealing solutions for many types of liquids and reagents as well as powders and courser materials.

The EPE Wad / liner (expanded polyethylene [EPE]) in our Polypropylene Closures offer excellent sealing qualities for our glass vials and bottles. The lined/wadded caps have a fine knurled finish allowing a secure grip for tightening and handling.

Expanded polyethylene (EPE) offers the following qualities:

  • flexibility even under cold temperature
  • resilient (total shape memory)
  • inert: resists to organic solvents and numerous chemicals
  • non toxic
  • waterproof
