Syringe Filter - 0.22 μm - PTFE
Sizes: 13 mm & 25 mm

Starting at: $1.75

Please Choose:

RAK Media brand PTFE 0.22µm syringe filter. Available in both 13mm and 25mm diameters. These autoclavable 0.22 micron syringe filters are made out of a hydrophobic PTFE and are 100% reusable. They are perfect for inserting into liquid culture jar lids to provide contaminant-free gas exchange. Compare to much more expensive Whatman brand filters... the only difference is the price!

The size you should choose is personal preference. Both filters function exactly the same.

Sold as a single unit. Please select a size below.

I ordered the 13mm diameter syringe filters to make my own LC lids. After a bunch of trial and error, I found that a 4mm drill bit was a good size to use to drill the holes. I'm not sure if the size would be different on the larger filters, but 4mm worked out well for the small ones! Also, mm drill bits are hard to find in hardware stores in the US so I ordered mine online.
