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.

• A: Particulates Trapped
• B: Particulate-free Sample

Recommendation Based on Your Industry

Environmental

Water, wastewater, soil and sludge, and pollution control samples are especially challenging. No matter the sample type, Phenex offers filtration products to meet your demanding requirements.

• Recommended Filter: GF/NY
• First Alternative: RC

Pharmaceutical / Biotech

At every stage of the drug discovery process target compounds must be isolated, purified, and prepared prior to testing. Sample complexity in DMPK work can be even more challenging. Difficult samples such as serum, urine, and other physiological fluids are easily filtered and clarified using Phenex syringe filters.

• Recommended Filter: PES
• First Alternative: RC

Clinical / Toxicology

Removal of particulate matter to sub-micron levels is critical before any clinical sample is injected into an LC, GC or mass spectrometer. At every stage in toxicology, samples should be filtered, preferably with a rapid and simple sample preparation method to reduce downtime in the fast paced environment. Phenex is designed for higher flow rates and throughputs than those of competing products.

• Recommended Filter: RC
• First Alternative: PES

Food and Beverage

Food safety is more important than ever and lower detection limits are making analysis even more challenging. Accurate and reliable testing is critical and Phenex filters are routinely used in preparation for analysis of pesticides, herbicides, fungicides, flavors, and fragrances. For samples with large amounts of particulate and/or large fibrous matter, use a glass fiber prefilter.

• Recommended Filter: GF/NY
• First Alternative: RC

How to Use Phenex Syringe Filters

Easy to assemble and even easier to get consistent and particulate-free samples

Step 1: Load

• 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).

Step 2: Assemble

• 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.

Step 3: Filter

• 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.
