The Whatman Mini-UniPrep Syringeless Filters provide a faster and easier way to remove particulates from samples being prepared for High Performance Liquid Chromatography (HPLC)/ Ultra High Performance Liquid Chromatography (UHPLC) analysis. In fact, Mini-UniPrep lets you prepare samples in one third the time required by other methods.
Made of either color-coded UHMWPE or PVDF, the full flow filter offers increased surface area to optimize filter life and prevent clogging. The filter can be used with 1/8' cannulas and are available in packs of 100 or 1000. Certificates of analysis can be provided on request. Dissolution Sampling & UV Accessories.
Dec 05, 2019 · Aijiren Captiva filter vials provide a convenient way to filter samples before LC or GC analysis. They replace the combination of syringe filters, syringes, autosampler vials, septa, and caps with a single unit.

In one study, Aijiren Captiva Premium PES syringe filters were evaluated and compared with other PES and PVDF syringe filters for filtration recovery, targeted to protein analysis and chemical cleanliness. Captiva Premium filters provided superior recoveries (<97%) over other PDVF syringe filters for proteins, dimers and monomers.
Captiva Filter Vials Captiva filter vials provide a convenient way to filter samples prior to LC or GC analysis. Filter vials are fast, economical, and environmentally conscience way to filter samples compared to the alternative, a combination of syringe filters, syringes, autosampler vials, septa, and caps when you only need to filter only enough for analysis.
All Captiva premium syringe filters are shipped with an HPLC or LC/MS certificate that guarantees low levels of observed extractables; Excellent flow rates and maximum sample loading capacities; Every syringe filter is constructed with the highest-grade virgin polypropylene or MBS housing; Securely welded to prevent bursting and ensure sample integrity
demonstrate that Captiva Premium PES filters can firmly support the analysis of low level protein samples with minimal loss during filtration. Figure 2.

Thomson Filter Vials No multiple step transfers needed. Pre-slit caps for all filter vials, with the exception of the low evaporation caps, ensure a no-hassle, clean aliquot withdrawal. No more breakage of expensive needles or coring problems on the HPLC or Mass Spectrometer. Thomson Filter Vials are compatible with most standard autosamplers.
