Frequently asked questions (FAQs)

How do I use Thermo Scientific Nalgene glass fiber prefilters?

Glass fiber prefilters are available as an optional accessory (DS0281 series) and bundled with select Thermo Scientific Nalgene Rapid-Flow filter units. They are useful in filtration of solutions with an especially high particulate load, often enabling a higher volume to be filtered before significant flow decay by trapping and preventing the larger particulate matter from entering the final filter membrane. Simply place one prefilter on top of the membrane bonded inside the unit, wet slightly to hold in place, and proceed with filtration as usual.

What is the effective pore size of Thermo Scientific Nalgene glass fiber prefilters?

Our glass fiber prefilters have an effective pore size of 1.0 to 1.3 microns.
