Captiva filtration products are available in a range of sizes, formats, and membranes. The Captiva syringe filters have high flow rates and large sample loading capacity. Every syringe filter is constructed with high-grade virgin polypropylene or MBS housing, and is securely welded to prevent bursting and ensure sample integrity. The integrated microfiber glass prefilter can also filter solutions without adversely affecting the efficiency of the membrane. Prefilters can reduce the effort required to move highly particulate-laden samples through a filter and eliminate the need for sequential filtration. All Captiva Premium syringe filters are supplied with a HPLC or LC/MS Certificate.
