PTFE Syringe Filters w/ GD4 Prefilter

Tisch PTFE Syringe Filters with the GD4 Prefilter are ideal for especially viscous or difficult to filter samples. The GD4 prefilter is built with a 10um Glass Fiber, 1.0um Polypropylene, and 0.7um GF/F membrane on top of the final PTFE Membrane Media.

PTFE is ideally used in applications that require the filtration of harsh chemicals and acids that can teardown other membrane media.

Tisch PTFE Syringe Filters with the GD4 Prefilter are stocked in our Cincinnati, Ohio warehouse and can be shipped out in one business day. We offer free samples for testing prior to purchase and have a technical support staff available to assist you during all business hours. Please don't hesitate to contact us if you have questions.
