It is important to know that your heat sealer is performing as it should be. A poor seal can lead to compromises in the sterility of the contents inside the heat sealed pouch. Instruments that are not properly sterile can lead to Surgical Site Infections (SSIs) which can harm the patient.
Fortunately, there are preventative steps that you can take to avoid SSIs. In addition to producing high quality heat sealers, Hawo have also come up with several different ways of checking the integrity of your heat sealed pouch. The Seal Check, Ink Test, and Ink Test PRO are three ways of checking the quality of a seal. Furthermore, users can combine one or more of the options below with a pouch destruction test which is carried out by one of our in-house, Hawo trained engineers.
Ink Test PRO
The InkTest PRO is an innovative take on the standard ink test. It is used for the routine testing of all four sides of the pouch and fully complies with ISO 11607-1 and ASTM F1929. Using the ink test PRO is easy. Users simply place one of the silver sachets into a pouch and seal it as normal. Then the sachet is squeezed until it bursts and the blue ink is ejected. The ink then moves around inside the pouch and any flaws in the seal seam will become visible.
The ink test PRO is easy to use and much cleaner than conventional pipette ink tests. To see how the Ink Test PRO works, you can view this video.
|This is the standard ink test using a pipette and bottle of ink. It complies with ISO 11607-1 and ASTM F1929 and allows users to clearly see any defects in the seal. The ink test can be used with all types of paper/film pouches including Tyvek®.
