More About this Item

Filters are Triton-free and have a bidirectional membrane support and luer lock (15/25 mm dia) or stepped barbs (50 mm dia) inlet/outlet for a secure fit to the syringe. Membrane type and pore size are printed on each filter for easy identification. All Cole-Parmer syringe filters are 100% integrity tested and manufactured in accordance with ISO 9002 standards. Sterile filters are sterilized by gamma radiation. They are certified nonpyrogenic, noncytotoxic, and are blister packed.

Warning: This product is not approved or intended for, and should not be used for medical, clinical, surgical or other patient oriented applications.

REVIEWS

Q&A

I want to use it upstream of an inlet line. Does the tubing attach to the IN side and the other side face the instrument or is it the other way round?

Bud

Either side of this filter features a stepped hose barb. The hose barb accommodates flexible tubing inner diameters ranging from 1/4" to 1/2"

Eric

I want to use it upstream of an inlet line. Does the tubing attach to the IN side and the other side face the instrument or is it the other way round?

Bud

The inlet should receive the incoming, unfiltered media.

Mike

What is the maximum flow rate of air for these filters?

Ann

There is not a real specific speed, but this can only have a pressure rating of 60 psi before there is damage to the filter. Flow rate also depends on how much material is left behind due to not passing through the filter.

Anthony

Is the membrane hydrophobic or hydrophilic

luc

The PTFE membrane is Hydrophobic but solvents can filter pretty easily

Polo

Are these filters hose barb as shown on picture? What's the tubing range?

Luc

The fitting is a 1/4" barb on each end

Maximum pressure is listed as 60psi @ 25C. How does temperature affect the maximum pressure rating? Is there a derating to be applied at +60C? Or 0C? Or -40C?

If other temperatures are used it could affect the maximum pressure. Very hot or very cold samples could affect the maximum pressure possibly decreasing it. The only verified testing results only have that one specification of 60 psi @ 25 C.

Rita

I like to know diameter of filter

wick

The membrane diameter is 50 mm. Overall the diameter is 64.3 mm and from hosebarb tip to hosebarb tip (overall height) is 69 mm. The hosebarb connections on this unit will accept 6-12mm ID tubing on both sides. The fittings are nominally 1/4 inch though they actually taper from 12 mm to 6 mm.

Jen

I plan to use these PTFE filters to sterilize gas (air, N2) entering fermentation vessel 1) Can I autoclave these filters? 2) If they are resistant to autoclave, how many times they can be used in fermentation experiments? Thanks

Nicolai

The housing is PP and the membrane is PTFE, both of which are okay with repeated sterilization via autoclave (we do not have a suggested/specified number of times).
