GPL-501B: Gas Pressure Leak Tester

The Confluent Medical Technologies gas pressure leak tester, model GPL-501, is a tabletop machine used for nondestructive leak testing of catheter components using dry nitrogen gas. Nitrogen gas is inert so there is no residue, water spots or water droplets on catheter components, making it ideal for testing of finished devices.

Parameters Include

  • Vacuum test
  • Ramp rate
  • Test time
  • Test pressure
  • Hold time
  • Maximum leak rate
