hawo InkTest
INK TEST WITH PIPETTE.

Our hawo InkTest is a classic ink test for the routine testing of sealed seams using method C (according to EN 11607-1/ASTM F1929-23), also known as pipette test. For this purpose, a special test liquid is added to the bag or film tube by using a pipette. Any irregularities that may occur (e.g. channels) become visible immediately. Thanks to the practical pipette, sealing seams can be tested from both sides. 

The hawo InkTest comes in a 75 ml bottle together with pipettes and a drip tray.
