Self-adhesive Lid Filters - 48mm

These 48mm self-adhesive lid filters apply to jar lids, tubs and tissue culture containers, giving a large breathing area for projects that need high gas exchange while protecting your culture from contaminant spores and bacteria. The 40mm oleophobic and hydrophobic filter window resists steam breakdown and moisture saturation, and a strong 3M adhesive backing on a transparent base film makes application fast and tool-free. Fully autoclavable. Supplied 8 filters per sheet.
