Agilent Captiva Syringe Filters
All pictures shown are for illustration purpose only. Actual product may vary.
Agilent Captiva syringe filters provide reliable mechanical filtration for HPLC, LC-MS, ion chromatography and general sample preparation workflows. Designed to remove particulates before analysis, Agilent syringe filters help protect columns from blockage, high backpressure, retention-time shifts and loss of resolution, supporting longer column lifetime and more consistent analytical performance.
Available in a choice of membrane types, pore sizes and formats, Captiva syringe filters are suitable for a wide range of sample types and laboratory requirements. The range includes both Agilent Premium syringe filter options for low-extractable applications and Agilent Econofilters for routine, high-throughput filtration.
- Premium Range: Agilent premium syringe filter products are supplied with an HPLC or LC-MS certificate, confirming extremely low levels of observed extractables for sensitive analytical workflows.
- Econo Range: Agilent Econofilters offer a cost-effective option for busy, high-volume laboratories requiring reliable filtration for routine sample preparation.
Features
- Premium filters are available in PTFE, nylon, PES, regenerated cellulose, cellulose acetate, and glass microfibre membranes
- Econfilters are available with PVDF, PTFE, nylon, PES, polypropylene and regenerated cellulose membranes
- Choose from 0.2 um or 0.45um pore sizes
- Use with Agilent disposable syringes to remove particulates from samples
- Captiva syringe filters have excellent flow rates and maximum sample loading capacity
- Syringe filters are constructed with the highest-grade virgin polypropylene or MBS housing
- Securely welded to prevent bursting and ensure sample integrity
- Layered filters have an integrated microfiber glass pre-filter and are used reduce the effort required to move highly particulate-laden samples through a filter and eliminate the need for sequential filtration
- Premium syringe filters are shipped with an HPLC or LC-MS Certificate that guarantees extremely low levels of observed extractables
- Econofilters are available in money-saving packs of 1000
Specification
| Membrane | Type | pH Range | Key Properties |
| PTFE | Hydrophobic | 1 to 14 | Broad chemical compatibility, highly resistant to strong acids and bases |
| Cellulose Acetate | Hydrophilic | 4 to 8 | Very low protein binding |
| Regenerated Cellulose | Hydrophilic | 3 to 12 | Broad chemical compatibility, also low protein binding. Suitable for most HPLC & UHPLC applications. |
| Nylon | Hydrophilic | 3 to 14 | Broad chemical compatibility, excellent choice for organic solvents and samples with higher pH. |
| PES | Hydrophilic | 3 to 12 | Compatible with aqueous solutions, and some organic solvents extremely low extractables and excellent flow rates; low protein binding. |
| Glass Microfiber | Hydrophilic | 1 to 14 | Used as a pre-filter, broad compatibiltiy with organic solvents and strong acids. |
| Glass Microfiber/Nylon | Hydrophilic | 3 to 14 | Best for highly particulate laden samples; compatible with most organic solvents. Not suitable for protein recovery applications. |
| Glass Microfiber/PTFE | Hydrophobic | 1 to 14 | Best for highly particulate laden samples; broadest chemical compatibility, particularly with strong acids and bases. |
