• Vials minimize sample loss by eliminating multiple transfers. • Color-coded caps allow easy identification of 0.2 μm or 0.45 μm membranes in PVDF, PTFE, PES, or nylon.
Filter Vials equipped with the Low Evaporation Cap offer the same characteristics as our standard Filter Vial. Filtering samples in-vial with a 3-step process (deposit sample & dilute, press plunger to filter, place in HPLC). Even with a seemingly homogenous sample, filtering with a Thomson Filter Vial is fast and eliminates HPLC downtime.
Cytiva's Whatman Puradisc line is a comprehensive syringe filter portfolio used in a variety of applications. Cytiva also offers high-performance GD/X syringe filters with a multi-layer glass fiber prefilter for filtering larger volumes of harder-to-filter samples. Polyvinylidene difluoride (PVDF) membranes.
13 filters are available with a special tube tip outlet that allows the sample to be accurately dispensed into a micro-vial, eliminating air lock. Membranes are available in Nylon, Polystyrene (PS), Cellulose (CA), Teflon (PTFE), Polysulfone (PSU) or Polyvinylidene fluoride (PVDF).
samples containing < 10% particulates. Thomson Standard Filter Vials can be used for samples containing less than 10% solid particulates. The filter vial consists of two parts: a filter vial shell and a plunger which includes a single layer filter on one end and a vial cap on the other end. Applications for Standard Filter Vials include filtration of catalysts from organic and medicinal chemistry synthesis reactions, saccharide analysis in corn syrup, and in-vial protein precipitation.
The Thomson Filter Vials were evaluated to replace the filtering step using a syringe and syringe filter. it through each of the four vial types (PES, PVDF, PTFE ...
sample, which allows for the use of a less stringent filtration method, such as filter vials. Use of the Thomson eXtreme|FV ® 0.2µm PVDF (polyvinylidene fluoride filter vials) significantly decreases the filtration time, as well as alleviating the need for additional solvents and buffers. (Thomson Instrument Company, 2015)
There’s even an eXtreme version of the Thomson vial that has a multi-layer filter for samples with 10-30% particulates. Both vial types are very simple to use with a lot less mess, hassle, and waste compared to a separate syringe, disc filter, and collection vial. Here’s an example using a 0.2µm PVDF filter vial for the analysis of
Single StEP ™ PVDF filter vials were purchased from Thomson Instrument Company. UV-visible spectra were acquired on a UV-Vis Cary 50 (Aijiren Technologies).

Jul 26, 2019 · The individual samples were processed as follows: i) one sample was left unfiltered to act as a positive growth control; ii) a 200 μL volume of a sample was filter sterilized using a sterile Olympus 0.22 micron PES syringe filter; iii) a 250 μL volume of a sample was filter sterilized using a non-sterile Thomson Standard 0.2 micron PVDF
Accommodating A Variety of Sample Types. Filter Vials are a single system which replaces HPLC Vials, HPLC Caps, Syringes, & Syringe Filters for the filtration of samples. In 15 seconds, Thomson Filter Vials allow for sample preparation of unfiltered samples to filtered samples in an autosampler-ready vial.
Recommended for samples containing less than 10% solid particulates. Easy-to-use vials offer fast sample filtration and require only a squeeze of your fingers. Minimize sample loss by eliminating multiple transfers. Color-coded caps allow easy identification of 0.2 μm or 0.45 μm membranes in PVDF, PTFE, PES, or nylon.
