Thomson Filter Vial Application Notes

Download the catalogue of application notes below.

Standard Filter Vials (120L Dead Volume)

Thomson Standard Filter (patented) can be used for samples containing less than 10% solid particulates. The lter vial consists of two parts: a lter vial shell and a plunger which includes a single layer lter on one end and a vial cap on the other end. Applications for Thomson Standard Filter Vials include ltration of catalysts from organic and medicinal chemistry synthesis reactions, saccharide analysis in corn syrup, and in-vial Max Fill Vol. protein precipitation.

eXtreme|FV® (Multi-Layered Filtration)

Thomson eXtreme|FV® (patented) oer multi-layer ltration for viscous samples and samples containing up to 30% solid particulates. The lter vial consists of two parts: a lter vial shell and a plunger which includes a multi-layer lter on one end and a vial cap on the other end. eXtreme|FV® allow for compounds to be separated from the matrix which, results in both a higher signal to noise ratio and peaks that are more dierentiated. Prior to the introduction of the eXtreme|FV®, many samples containing high levels of particulates were “ltered” by using an SPE step in the method. These methods are readily amendable to the replacement of the SPE step using a rapid and lower cost eXtreme|FV® step.

Applications for Thomson eXtreme|FV® include ltration of cell and cell debris from cell culture; pesticide analysis in food, tissue, soil, and water; and toxicology analysis in blood and urine.

nano|Filter Vials™ (10μL Minimum Volume)

Thomson nano|Filter Vials™ oer a very low dead volume allowing one to lter as little as 10μL of sample with enough remaining ltrate to make a 2μL injection. The lter vial consists of two parts: a lter vial shell with mating bottom surface and a plunger which includes a lter on one end and a screw cap vial on the other end. Applications include the analysis of enzymes, peptides, DNA, RNA, synthesis reaction intermediates, nished products, saliva, samples available in low volumes, in-vial evaporation and re-suspension for sample concentration and buer/solvent change.
