homogenate was weighed into a Thomson™ eXtractor 3D|FV® filter vial (0.45 µm PVDF membrane) and acetonitrile was added (1 µL acetonitrile per mg homogenate). Internal standards and analytes (for spiked samples) were added in the acetonitrile. The filter vial was capped and vortexed for 1 minute. It was then filtered by depressing the plunger.
Thomson Filter Vials simplify general filtration by replacing syringes & syringe filters, microcentrifuge spin columns, and/or liquid-liquid extractions. Applications for Thomson Filter Vials include all sample types to be analyzed by HPLC, UHPLC, LC-MS, and GC-MS. Max Fill Vol. 450 µL Dead Vol. 120 µL Standard Filter Vials (120μL Dead Volume)
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. Preslit PTFE/silicone caps help eliminate broken autosampler needles and cored septa.

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.

Phenex syringe filters are designed for efficient and rapid filtration of almost any solution prior to analysis, and are optimized for superior flow rates and high throughput. Proper membrane and size selection are the keys to choosing the best product to maintain the integrity of your sample components as well as to protect your system from
Thomson SINGLE StEP Low-Evaporation Filter Vials. Enhanced evaporation prevention technology, and no preslit in the cap membrane ensures less than 0.4% evaporation over 24 hours. Easy-to-use vials offer fast sample filtration and require only a squeeze of your fingers.
Single-Step Filter Vials. time of equipment are costly. A simple upfront and easy solution is the incorporation of Thomson Filter Vials. The Thomson SINGLE StEP Filter Vials 35540-200 (200 per pack) or 35540-500 (500 per case) (patent pending) are comprised of three parts: Pre-slit cap, plunger filter with 0.45µM Teflon membrane and the outside shell vial that holds 450uL.
Similar to how a french press (cafetière à piston) works, Filter Vials filter particulates out of the sample with similar membranes used in syringe filters. The pressing of the plunger into the shell vial forces the sample up through a filter to separate the particulates from the sample to be analyzed. Thomson has several filter membranes and pore sizes to choose from making the Filter Vial a versatile tool in the lab.
