Whirl-Pak® Filter Sterilized Bags

Whirl-Pak® Sterilized Filter Bags simplify pipette sampling with a built-in 330-micron full-page filter that keeps solid particles contained on one side of the bag. This prevents pipette blockage and ensures clean samples for even plate distribution. Designed for both liquids and solids, these sterilized bags provide secure, leak-proof storage and contamination-free handling. Key Benefits:

• 330-micron filter layer ensures solids are contained while liquids transfer for clean sampling.
• Write-on label area allows quick and clear identification.
• Leak-proof seal with Whirl-Pak’s signature continuous perimeter design.
• Post-manufacturing sterilization (+1 Sterilization) guarantees sample integrity.
