Type I Borosilicate Glass Vials
Type I borosilicate has the least pH shift of any glass. It is highly resistant to water, neutral and acid solutions, concentrated acids and acid mixtures, and to chlorine, bromine, iodine and organic substances. Its chemical resistance is superior to that of most metals and other materials, even during prolonged periods of exposure
and at temperatures above 100°C.  

Carefully Engineered Closures
All materials are fully tested pre- and post-production with material certification and data available to customers.

  • We are dedicated to providing the highest quality liner materials and assembled caps for multiple industries.
  • All products are tested for the lowest levels of material extractables.
  • During production the caps and seals are continually monitored by state-of-the-art equipment and all products are tested in a fully equipped laboratory.
