These treated filter cap flasks exclude microorganisms to protect unique primary cell cultures, stock cell lines, and infectious cultures from cross-contamination. Provide optimal gas exchange. Ideal for efficient cell growth. The 35–90 mL flask (VPN 178983) features a 10-digit alphanumeric bar code on one side that can be read by conventional bar code scanners.
Cap design seals tightly using a filter area proportional to flask volume for supportive gas exchange. Welded to the high-density polyethylene cap, the hydrophobic filter won’t clog with media or air moisture.
