Syringe filter for sterile lab work
These PTFE syringe filters ship sterile and are ready for single-use filtration of aqueous or organic solutions up to 10 mL. The 0.22 µm pore size removes bacteria and fine particulates from samples before analysis. A female Luer lock inlet and male Luer slip outlet fit standard syringes without adapters. The 13 mm housing keeps dead volume low for small-volume work.
PTFE membrane withstands aggressive solvents
PTFE resists most acids, bases and organic solvents, so the same filter can handle aqueous and non-aqueous samples. The housing is rated to 65 psi or 4.5 bar, allowing moderate pressure from a hand syringe or low-pressure pump. Sterile packaging eliminates the need for pre-rinsing or autoclaving before critical assays. The pack of 75 supports routine throughput in busy labs.
Limited to small volumes and manual pressure
Maximum capacity is 10 mL, so larger batches require multiple filters or a different format. The 0.22 µm rating does not remove viruses or the smallest mycoplasma species. Hand-syringe pressure may exceed the 65 psi limit if the membrane clogs, risking housing rupture. Male Luer slip outlets can disconnect under pressure compared with locking outlets.

Questions about this item
What pore size does the PTFE membrane use and what particle retention does that provide?
The membrane has a 0.22 um pore size, which retains bacteria and fine particulates during sterile filtration of aqueous or solvent-based samples.
What are the inlet and outlet fitting types and the housing diameter for this filter?
It has a female Luer Lock inlet, a male Luer Slip outlet, and a 13 mm housing diameter that fits standard 13 mm syringe filter holders.
How is the filter attached to a syringe and what common mistake should be avoided?
Twist the female Luer Lock inlet onto the syringe tip until firm; do not overtighten, which can crack the housing or damage the membrane.
