Whirl Pak® plastic bag, 23 x 11.5 cm (L x W)

Versatile sample bags especially suitable for liquid samples for food, water and wastewater analysis, but also for biological or chemical samples.

To open and close the bag, the filling opening is backed on both sides with a metal clip which also keeps the opening taut at all times.
For hermetic sealing, hold the bag by the metal clip and spin it around its own axis several times, then fold in the two ends of the metal clip and press tightly. The Whirl-Pak® can be opened and closed as often as required.
A strong weld seam on all sides guarantees additional safety.
