Refillable Permeation Tubes

KIN-TEK Trace Source refillable permeation tubes:

  • Have a broader concentration range than the Trace Source disposable permeation tubes.
  • Are recommended for long-term use and special applications requiring a wide range of calibration points.
  • Are available for chemicals that are not typically suitable for disposable permeation tubes such as CO, CO2, NO, methane, ethane, arsine & phosphine. 
  • Emission rate of the tube membrane is certified by the Factory
  • Most tubes are periodically returned to KIN-TEK for refill and recertification.

LFH Liquid-filled
57S and 57H Gas-filled
57 Series Prefilled

I. LFH Liquid-Filled Permeation Tubes

  • Generates moderate to high concentration mixtures of low vapor pressure liquids such as acrylonitrile, benzene, methanol and water.
  • Are usually filled by KIN-TEK before shipment but may be filled by the customer (with appropriate safety measures in place) for certain components (contact the Factory)
  • Tube dimensions: 1¾ inch diameter by 6 inch height plus approx. 2 inch height of protruding tubing

II. 57S Gas-Filled Permeation Tubes

  • Generates low concentration gas standards of high vapor pressure gases such as CO, CO2, NO, N2O, CH4 etc.bes
  • Typical concentrations: sub-ppb to 10 ppm depending on tube emission rate and dilution flow rate
  • Tube dimensions: 1¾ inches diameter by 6 inches long 
  • Are usually filled by KIN-TEK but may optionally be filled by the customer (with appropriate safety measures in place) for certain components (contact the Factory). Customer-refill may require a gas feed "GF" module of the 491M or FlexStream gas standards generator.bes
  • Tube dimensions: 1¾ inch diameter by 6 inch height plus approx. 2 inch height of protruding tubing

III. 57H Gas-Filled Permeation Tubes

  • Generates high concentration mixtures of high vapor pressure gases CO, CO2, and NO
  • Typical concentrations: 10 ppm to over 1,000 ppm depending on tube emission rate, dilution flow rate and operating pressure
  • Are filled by the customer using the controls of a gas feed "GF" module of a KIN-TEK 491M or FlexStream gas standards generator
  • Tube dimensions: 1¾ inch diameter by 6 inch height plus approx. 2 inch height of protruding tubing

IV. Prefilled Permeation Tubes

Series 57 Prefilled Permeation Tubes are used in KIN-TEK gas standards generators to create gas standards ranging from less than 50 ppb to 5 ppm (depending on tube emission rate and dilution flow rate) for arsine and other hydride gases, as well as highly reactive gases such as HCl, HBr, O2 and CO. The high vapor pressure of these compounds makes them unsuitable for use in disposable permeation tubes. Download brochure

  • Factory-prefilled permeation tubes
  • Factory-certified emission rate
  • Small amount of toxic material (typically less than 4 grams of pure gas under 50 psig)
  • Capable of safely using the gas phase of high vapor pressure compounds bes
  • Tube dimensions: 1¾ inch diameter by 6 inch height plus approx. 5.5 inch height of pressure gage and protruding tubing (requires removal of some KIN-TEK instrument covers)

V. Refill and Recertification

  • Return (with RMA number) to us for refill and recertification.
