Dec 07, 2020 · When choosing a syringe filter, three main factors dictate your syringe filter selection: sample volume, potential particulate size, and filter membrane compatibility. Diameter of the Syringe Filter and Sample Volume Sample volume dictates the diameter of the syringe filter.
To filter your sample, simply attach the appropriate syringe filter to the NORM-JECT and HENKE-JECT syringe and depress the plunger, capturing the effluent in a collection vial. Be sure to choose the correct volume syringe for the sample volume you wish to filter.
Simplify sample preparation with the Whatman™ regenerated cellulose membrane portfolio from GE Healthcare • Reduce cost with well-designed devices – the regenerated cellulose (RC) family includes products for robotic sample handing, outside-of-lab sample preparation, certified method development, and working with hard-to-filter samples.
A full range of syringe filters. Syringe Filters with membrane types to suit most HPLC/UHPLC applications. Guide to selecting the right syringe filters. 1. Choose membrane type. Nylon - Broad solvent compatibility, Aqueous and organic materials. PTFE - Ideal for HPLC, UHPLC sample preparation and excellent solvent resistance
Nov 15, 2014 · The choice of syringe filter depends on the: filter size (volume) of your sample, the chemical compatibility of the housing and membrane and desired pore size.Selection of the wrong filter size can result in too much sample holdup volume (loss of sample on filter) or overloading of the filter (allowing unfiltered material to pass through).
STERILE SYRINGE FILTERS – sterile syringe filters are made with PES membrane filters with polypropylene (PP) housing, using the most advanced methods and design features. The PES syringe filters with GF pre-filter has excellent dirt-holding capacity, which makes a syringe filter a much larger throughput for some “hard to filter” sample.
Over thirty years ago, Pall Life Sciences revolutionized sample preparation for analytical chemists with the develop - ment of the Acrodisc®syringe filter. Today we produce high-quality filters for sample preparation and dissolution testing that meet the unique requirements of every lab we serve. Pall’s microporous materials and filtration
Water and acetonitrile were passed through polypropylene or PTFE syringe filters (as indicated in legend), then used 1:1 (v/v) to prepare the mobile phase for UHPLC. The system was run at 0.25 mL/min for 600 min with backpressure recorded every 50 min. DP represents total change in backpressure after 600 min.
Syringe Filter, PTFE, 0.22µm, 30mm Diameter. Denville. luer-lock syringe and are color-coded for easy recognition. The 30mm syringe filters can filter up to 100mL of sample with a retention volume of less than 100µL. The 13mm filters can filter 5 to 10mL of sample and have a retention volume of only 28µL.
Feb 17, 2020 · A PTFE syringe filter is an ideal choice for filtering and de-gassing chromatography solvents. With proper pre-wetting (commonly used alcohol), aqueous samples are also compatible. When using air-vents, these syringe filters are capable of stopping moisture from passing through. Workable pH range: 1-14.
Use of Syringe Filter. Syringe filters are normally used for chemical experiments. For example, prior to analysis by HPLC, we can remove particles from a sample via syringe filter. HPLC can be easily damaged and blocked by the impurity particles due to the small packing size and high pressure.
Millex-LG for Samplicity G2, 0.20 µm, hydrophilic PTFE, 33 mm, non-sterile, This 33 mm syringe filter with a Hydrophilic PTFE membrane, for non-sterile filtration on the Samplicity G2 system, has a 0.45 µm pore size used in preparation of aqueous & organic solutions prior to chromatography or other instrument analyses.
How to Select a Syringe Filter and How to Use it? (2020 Guide) Feb 17, 2020 · Step 2: Attach a syringe filter to the Syringe. Open the syringe filter package so that you can later pick the filter up easily, especially for individually packed sterile syringe filters. a. For sample volume . 10 mL. Draw a small amount of air (about 1 mL) into the syringe before loading the sample solution.
Oct 02, 2019 · Filter Diameter: Syringe filter diameter depends upon the volume of the sample to be filtered. If the volume of the aqueous sample is Higher, the filter should be with a larger diameter. Syringe filters are available in a variety of diameters including 4mm, 13mm, 17mm, 20mm, 25mm, 30mm, and 33mm. For smaller volume samples (approximately 1 ml
If so, choose a filter with glass fibre (GF) membrane, e.g. GF / PTFE. 4. Select the appropriate membrane. Further information on the properties and application areas of the membranes can be found in the table below. Properties of Syringe Filters. The properties of syringe filters made from different materials are very different.
