Are you looking for an alternative to glass bottles for the storing and transportation of your critical solutions?

Glass bottles and containers were traditionally and still are being used in Biopharmaceutical companies due to the chemical compatibility they provide. However, with the ongoing issue of glass breaking during storage and transportation many are seeking a chemically compatible high-purity polymeric alternative.

The Issue:

  • Human error – dropping / in-correct packing
  • Glass delamination
  • Product contamination during dispense/filling

The Solution:

The Entegris NOWPak® offers a single-use liner-based containment and dispense system that insures the product is fully protected without the risk of contamination.


  • A durable plastic overpack provides a safe alternative to glass bottles
  • A collapsible liner system maximizes process fluid usage
  • The sealed dispense pathway reduces external contamination
  • Unique key coding helps prevent dispensing the wrong material
  • Amber colour HDPE overpack for light-sensitive process fluids
  • Ultra clean liner with low extractables
  • All PTFE and PFA wetted components allow use with a wide range of process fluids
  • Overpaks can be recycled and liners consolidated for cost-effective disposal
  • The canister system includes a pressurizable stainless steel overpack with a flexible single-use inner bag, a dip tube, a closure and a dispense connector, 4, 10, 20, 40 and 200-litre sizes
  • The bottle system includes an HDPE overpack with a flexible single-use inner bag. The dip tube is typically permanently attached to the dispensing connector used by the end user. Capable of pressure dispense at low pressures for a limited amount of time. Available in 1, 2.5, 4, 10 and 20-litre sizes
  • Single-use inner bag (Fluoropolymer or PE-based) can be pressurized to push material out, or a pump can also be utilized to pull it out
  • Components work together to deliver critical materials with purity, green, safety, and process efficiency

High Purity Applications

  • Liquid chromatography
  • Pharmaceutical manufacturing
  • DNA/RNA synthesis
