SureSeal*™
Certified Leak-free Cassettes

• Maximum sample collection and accurate results
• Eliminate filter bypass and plastic-to-plastic leakage
  
  
• Zero leaks under vacuum
• Verified by rigid quality control inspections
  
  
• Certified leak-free
  
  
• Available in standard, solvent-resistant, and conductive materials

Through precision molding and a rigorous in-process quality assurance program, SureSeal cassettes are produced to ensure that they will not leak under vacuum. Only cassettes that meet these exacting standards are certified leak-free and carry the SureSeal. Look for the SureSeal as your assurance of quality and accuracy.

* SureSeal is a trade name of Omega Specialty Instrument Co., a member of the SKC family of operating companies. SureSeal leak-free cassettes require the use of a SureSeal Cassette Opener 225-13-5A

SKC certifies cassettes as leak-free if cassettes can retain a constant vacuum (24 inches of mercury) with a less than 1 inch of mercury decay per second for 30 seconds and a constant pressure (5 pounds per square inch [PSI]) with decay of less than 1 PSI per 30 seconds.

 

The SureSeal Advantage

SKC SureSeal certified leak-free cassettes eliminate filter bypass and plastic-to-plastic leakage for the most accurate sampling.

Problem:	Filter bypass can result in significant error by underestimating the sample or, in extreme cases, a "false negative" measurement.
Solution:	SureSeal certified leak-free cassettes eliminate filter bypass.
Problem:	Plastic-to-plastic leakage increases sample size and is not representative of the sampled air that enters the inlet of the cassette. Due to the restriction of the plastic-to-plastic pathway, even poorly constructed cassettes can filter out 30- to 40-micron particles, which are not retained by the filter as part of the air sampled. The contaminant would be underestimated.
Solution:	SureSeal certified leak-free cassettes are precision molded and rigorously leak tested to eliminate plastic-to-plastic leakage.
