Pre-Pulled Glass Capillaries Used For CCIT (Closed Container Integrity Testing)

Pre-Pulled Glass Capillaries Used For CCIT (Closed Container Integrity Testing)

WPI pre-pulled pipettes are a popular choice for pharma companies carrying out CCIT (Closed Container Integrity Testing) as each one is individually tested and inspected and can be shipped with a certificate of compliance.

 

CCIT is an important part in understanding the biological safety and suitability of primary packaging. It is used to assess the potential of the container closure system to maintain a seterile barrier or to prevent leakage resulting in contamination or loss of the drug. A good overview of Understanding Container Closure Integrity Testing can be found on the American Pharmaceutical Review site

WPI can quickly supply your need for consistently sized, pre-pulled, glass, calibrated micropipettes. Tip diameters (ID) range from 0.1 to 30 µm. Silanized Tips with a Luer Shank connector are available. These glass needles are fabricated from Schott Duran borosilicate glass. 

 

  • Every glass pipette individually tested and inspected
  • Schott Duran borosilicate glass pipettes
  • 0.5 µm and smaller ID micropipettes include internal glass fiber for easy filling
  • Tip inner diameter tolerance ±20%
  • Short taper yields high strength
  • Nominal length ≈ 50 mm
  • OD:ID = 1.33:1
  • Options for plain shank or Luer fitting
