Filter Vials
Thomson Filter Vials
- Integrated filter, vial, and cap—all in one streamlined design
- Simple press-down operation—no tools required
Thomson Filter Vials eliminate the need for multi-step sample transfers by combining filtration and sample containment in a single, convenient device. Each filter vial includes a pre-slit cap (excluding low evaporation caps) for effortless, clean aliquot withdrawal without needle breakage or coring—reducing the risk of costly instrument downtime.
Designed for seamless compatibility with most standard HPLC and LC/MS autosamplers, these vials make filtration fast, clean, and repeatable. Their simple push-down design ensures reliable sample processing, making them indispensable in analytical and research laboratories.
Protein Crash Simplified
Protein precipitation prior to HPLC analysis is often performed offline using separate equipment. Thomson PTFE Filter Vials streamline this process by allowing protein crash and filtration in one step—mixing acetonitrile and aqueous solution directly in the bottom chamber. As the filter is pressed down, proteins are trapped while the clean filtrate passes through, ready for injection into the HPLC system.
Frequently Asked Questions
What makes Thomson Filter Vials different from traditional filtration methods?
Thomson Filter Vials combine the filter, vial, and cap in one device—removing the need for syringes, membranes, or transfer steps. This design reduces contamination risk and improves workflow efficiency.
Are Thomson Filter Vials compatible with my autosampler?
Yes. Thomson Filter Vials are designed to fit most standard HPLC and LC/MS autosamplers without modification or additional adapters.
Can Thomson Filter Vials be used for protein crash preparation?
Absolutely. The PTFE-filter version allows protein crash and filtration in one step by mixing acetonitrile and aqueous phases, trapping proteins while collecting a clean, ready-to-analyze filtrate.
