Maximum Quality
A: Identification
Syringe filter membrane type and pore size are clearly marked on each syringe filter
B: Luer Lock Inlet Tip
Secures connections to prevent “blow off”
C: Sample Distribution Rings
Creates even sample distribution for high sample flow rates
D: Medical Grade Polymer Housing
Offers the most inert syringe filter and helps eliminate unwanted secondary
interactions with the filter housing
E: Ultrasonically Welded
Ensures robust housing - filter integrity
Guaranteed Reliability and Consistency
Quality filtration products from Phenomenex offer a convenient way to clean up your samples - for improved analytical results with a simple method. Phenex syringe filters are designed for efficient and rapid filtration of almost any solution prior to analysis, and are optimized for superior flow rates and high-throughput. Phenex offers a wide variety of membranes ideal for any application.
- High quality filtration product
- Increased column lifetime
- Less system downtime
The housing attaches to any standard luer lock syringe, so the sample can easily be pushed through the membrane with minimal pressure. The result is a particulate-free eluent that is ready for use with LC, GC, or other analytical techniques. One of the most popular sample preparation methods is filtration using a sample preparation solution. It has the ability to remove particulates before injection onto the column and the ability to use it in parallel with another sample preparation technique. It requires no method development.

Other Applications:
* Removal of high particulate matter with a glass fiber prefilter is critical before any drug, tox, or dirty environmental sample is filtered to ensure the highest syringe filter membrane performance.
** For high load and particulate-laden samples you may consider placing a Glass Fiber (GF) prefilter, either integrated with the membrane as one unit (Phenex-GF/NY or -GF/CA) or in series with the membrane syringe filter of your choice. Generally, 0.45 µm porosity filters are used to remove particulates from samples and mobile phase solutions. For sterile-filtration, a 0.20 µm porosity filter can be used.
How to Use Phenex Syringe Filters
Easy to assemble and even easier to get consistent and particulate-free samples
Fill a syringe barrel with the liquid sample. Allow a small amount of air (approximately 10 % of the sample volume) to enter the syringe. The air is used as a purge to minimize fluid retention when expelling the sample from the syringe (Step 3 below).
Twist the luer lock end of the filter securely onto the syringe.
(Caution: Do not use syringes without a matching luer lock, otherwise the pressure applied may cause the filter to come off unexpectedly.)
Apply gentle pressure to the syringe plunger.
(Caution: Small syringes can generate excessive pressures.) Push the liquid sample, as well as the remaining air, through the syringe filter to maximize sample recovery.
