Are there non-disposable options for syringe filters? A threaded assembly that houses a filter, which can be disassembled, washed, and the filter replaced?

We do not offer items of this description. All our syringe filters are intended to be single use.

May I use the filters (SF1070G) as an inline filter for VOC suggested in method 1311? As well, may I use these filters for filtering a small portion of liquid sample for VOC analysis method 1311

These filters do fit the specifications for method 1311. Typically, samples for VOC analysis are tumbled in a zero headspace extractor that has a filter already in it. If additional filtration is required this filter could be used provided adequate measures are employed to protect the sample from losing VOC\'s through exposure to open air.

In a paper it mentioned: The Tefon scafolding was removed from a PTFE flter (Catalog No. SF200T,EnvironmentalExpress). I wanted to ask what did they mean by removing teflon scafolds? Thanks

I am unsure what that could refer to. We do not use that term in any of our products. If you could send a copy or link to the paper to info@envexp.com we will review it and see if we can figure out what they might mean.

Does SF012G have a Lot number?

It does. All boxes of syringe filters should have the lot number printed on the label on the outside of the box.

Where can I receive a certificate of analysis for SF012G?

This product is not certified for any background contaminant levels and does not come with a certificate of analysis.

How can we find the certificate of analysis for SF045N (Nylon syringe filters)

This product does not have a COA associated with it.

Does SF012G have a binder?

It does not have a binder. This syringe filter contains the same filter material used in our ProWeigh filter lines. Namely 1.5 micron glass fiber filter without binder.

how uniform are the pores of this filter type?

Nylon filter papers are defined as having absolute pore ratings. This means that >99.8% of spherical particles of the pore size will be retained by the filter.

What syringes work with these filters?

Our syringe filters fit both slip leur and leur lock syringes. You can find them in our Disposable Syringes section under Syringe Filters in Chromatography.
