Whirl-Pak® Write-On Bag, 2041 mL (69 oz), 4mil ,Sterile
Designed for reliable, traceable sample collection, the Whirl-Pak® Write-On Bag (2041 mL / 69 oz) combines large-volume capacity with durable construction and easy sample identification. Made from blended virgin polyethylene film, this sterile sampling bag delivers excellent clarity, strength, and leak resistance for demanding laboratory, environmental, and food safety applications.
The integrated white write-on strip provides a convenient, smear-resistant surface for labeling samples using common pens or markers, helping reduce transcription errors and improve chain-of-custody documentation. A puncture-resistant wire closure with inner and outer tabs ensures secure sealing, while the continuous perimeter seal protects against leaks during transport, freezing, or storage.
Suitable for use across a wide temperature range, these bags can be frozen to ultra-low temperatures when handled properly, making them a versatile option for large sample volumes in regulated testing environments.
