Seals for Pharmaceutical and Medical Industries

fda-complient-seals-2

Seals for the pharmaceutical and medical industries must meet three different challenges:

  1. The seal must perform well in the operating conditions it will face.
  2. The seal design and materials must be suitable for pharmaceutical and medical use.
  3. The seal design must be suitable for the cleaning or sterilizing method to which it will be exposed.

The predominant approach to making seals for the pharmaceutical and medical industries has simply been to take seal designs for industrial applications and use materials that are approved for food contact. We have taken a different approach.

For many years, we have been developing and testing seals in house to meet the unique challenges presented by the sealing and transportation of fluids in the pharmaceutical and medical industries.

In addition to conforming to FDA 21 CFR code, we also have seal designs that are suitable for the following:

  1. Clean In Place (CIP)
  2. Clean Out of Place (COP)
  3. Sterilization In Place (SIP)
Examples of equipment sealed:
  • Batch retorts
  • Cell analyzer
  • Calorimeters
  • Shunts and stents
  • DAC chromatography
  • Dialysis machines
  • Fermentation vessels
  • Actuators and positioners
  • Endoscopes
  • SFE plants
  • MRI cold heads
  • Breast pumps
  • Hygienic pipework
  • HDLC
  • Skin graft harvesters
Examples of media successfully sealed:
  • Blood
  • Methanol
  • Micro-organic cultures
  • Steam
  • CIP fluids
  • Bodily fluids
  • CO²
  • Powders
  • Chemicals and solvents
  • COP fluids
  • DI water
  • Methylene chloride
  • SIP
  • Water
  • Autoclaving

With a wide range of specially developed compounds and designs, our engineers have a solid platform from which to design the optimum seal for your specific needs. All designs are reviewed by an engineer who has over 25 years of experience in the sealing industry, and each design can be discussed directly with the seal engineer.
