– Filtration area is 31% larger than comparable 25-mm syringe filters, increasing flow rate and filtration area

– Decrease your flow decay from particulate loading

– Minimize contamination of samples—housed in polypropylene that is naturally low in extractables

– Particle-free seal from ultrasonic welding

– Get better resistance to chemical degradation than acrylic housings

Syringe filter housings have a standard slip-luer fitting on exit port and full-thread luer-lock fitting on entry port for easier attachment. Syringe filters with prefilters increase syringe filter capacity and decrease back pressure during filtration.

This cut-away drawing of our improved syringe filter illustrates the use of our conical frustum design, which evenly supports the filter while allowing more open area for complete filtration of your sample.

Call our Technical Services Department at 800-745-8218 with your specifications or email your specifications to proddev@envexp.com. In most cases we will have your pricing in 48 to 72 hours.

Don’t see the right filter?

We will customize filters to your needs:

1. Choose filter size, thickness and diameter

2 Specify filter material

3. Specify filter pore size

4. What substances are being filtered?

5. How many filters are needed (volume)?

6. Do the filters require a certification?
