What are Filter Vials?
Filter Vials are a revolutionary device for in-line filtration for liquid and gas chromatography.
Standard Filter Vials have a pre-slit cap for easy needle puncture.
eXtreme|FV® have a multi-layered pre-filter that allows for filtration of solids and other particulates that would not allow any items through. This gives the ability to replace multiple syringe filters with one eXtreme|FV®.
What will my benefits be of my lab standardizing on Filter Vials?
Thomson Filter Vials give the ability to protect your HPLC or LCMS, UHPLC, GCMS like an oil filter protects the car. One wants to eliminate any particulates floating throughout the system.
What needle depth do you set your autosampler for all of Thomson Filter Vials?
5mm from the bottom.
What autosamplers does the Filter Vial work in?
The Filter Vial fits in any autosampler that uses 12x32mm or 2mL vials . Most autosamplers such as Agilent® and Waters®.
What is the Filter Vial made out of?
It is made from Virgin PP tested by LCMS.
What chemicals or compounds are compatible with Filter Vials & membranes
For chemical or compound compatibility with our Filter Vials & membranes see the Chemical Compatibility Index & Compound Compatibility Index in our Technical Library
What is the dead Volume in the Filter Vial?
120μL
What is the fill volume?
The total volume is 450μL or up to the fill line
Where does the liquid go when you squeeze?
The liquid or sample goes into the plunger part of the Filter Vial while the particulates are filtered out.
Which membrane would I use for a 51%+ Organic based sample?
Use PTFE or Teflon® membrane .
Which membrane would I use for a 51%+ Water based, which membrane?
Use PVDF (preferred), PES (mostly used for mammalian antibodies) , Nylon (older not as clean) membrane .
What membrane size should I use with 2μm or 5μm HPLC columns?
The membrane that would be best for 2μm column would be .2μm Thomson Filter Vials. We have seen in some cases doubling and tripling of life span.
The 5μm columns we would recommend the .45μm Thomson Filter Vials. We have seen in some cases doubling and tripling of life span.
What do I do if I have a protein?
We recommend for mammalian or Eukaryotic Cell using PES membrane .2μm. for Prokaryotic Cells (e.coli and fungi) we would recommend PVDF .2μm.
What if we are looking for food filtration?
We would use the eXtreme|FVs® (eXtreme Filter Vial) for foods due to the possibility of large particulates. We would use either Nylon or PVDF.
What if we are looking for Corn Ethanol filtration?
We would use the eXtreme|FV® (eXtreme Filter Vial) for foods due to the possibility of large particulates. We would use either Nylon .2μm or .45μm.
