Captiva Filter Vials

Captiva filter vials remove particulates from your sample and are ideal for simple mechanical filtration. Filtering samples before analysis can extend column lifetime, decrease instrument downtime, and improve sample integrity. Captiva filter vials reduce the steps in your gas chromatography (GC) or high-performance liquid chromatography (HPLC) workflow. Just fill, cover, and plunge!Filter vials are a fast, economical, and environmentally conscience way to filter samples. The single, convenient and easy-to-use unit replaces the combination of syringe filters, syringes, autosampler vials, septa, and caps. With Captiva filter vials, there are fewer touchpoints in the sample journey, meaning fewer chances for contamination. Plus, they allow you to filter only what you need for analysis, saving time. Available in both 0.2 µm (white septum) and 0.45 µm (red septum) pore sizes, as well as nonslit and preslit formats, we have a variety of membrane choices to meet your application needs. Caps are color-coded based on membrane type for easy identification. Choose from polytetrafluoroethylene (PTFE), nylon, polyethersulfone (PES), and regenerated cellulose (RC) membranes. PES filter vials are a great choice for protein analysis applications due to their low protein binding. RC filters are suitable for general filtration for aqueous based samples. Nylon is a versatile filter for particulate filtration from both aqueous and organic matrices, while PTFE is most suitable for organic solvents.
