The right size of the filter will ensure that the complete volume of the solvent in the syringe is filtered properly. Depending upon the solvent’s volume, the size of the filter must be selected. Improper size will be incapable of filtering the complete volume of the solvent.
Choose the right membrane type Aijiren Technologies offers a range of filters to remove particles down to 0.45 µm in diameter. To remove the smallest particles, filters are also available with a pore size of only 0.2 µm. Select the right membrane type to match
They can be used for sterilization during injection by placing the membrane between the syringe and the needle. Seitz filters are usually made of asbestos. They are pad-like and thicker than membrane filters. Sintered glass filters are an alternative type of filter
Nylon Membrane. Nylon membrane filters are hydrophilic in nature and thus does away with wetting agents, which are obtained while undergoing filtration of aqueous solutions. They possess impeccable strength, are resistant to heat, wear and tear and are highly flexible.
PAN is designed for fast water purification. 2. Decide an appropriate pore size. The pore size of a filter, stated in microns (aka micrometers or µm), is determined by the diameter of particles retained by the filter or by a bubble point test.
Choose the right syringe filter for your application. Luer lock syringe filters are available in a variety of porosities and membrane materials, including PTFE, PVDF, Alumina, Glass Fiber, Polyethersulphone, Polypropylene, Polysulphone, Nylon, Nitrocellulose and Cellulose acetate. Alumina Based Membrane Syringe Filters - (4)
For most aqueous and organic slovens in the lab, the Nylon syringe filters are compatible. Excellent flow rate and high throughput loading and affordable cost make nylon syringe filters a common choice for semiconductor industrial applications. This type of nylon filter is not optimal for protein samples with high non-specific binding.
Hold the syringe with the filter pointing up and “top off” by pushing a few drops through the filter. Place the filter tip over the collection container and push the sample through a syringe filter by applying gentle positive pressure.
To take the guess work out of filter selection and to help you choose the right filter, we have provided a quick application guide in this brochure. Additionally, interactive filter selection tools are available. The online version can be found at www.gelifesciences.com
Eliminate particles and microorganisms from your sample — reliably. Prevent the accumulation of fine particles that can block your chromatography column. Thermo Scientific Titan3, Target2, and Choice SyringeFilters remove interfering materials, fine particles, and microorganisms, providing you with cleaner sample extracts.
A combination of blue light filter and anti-reflective reduce eye strain and over-stimulation resulting from light-rich environments. The glasses should give the client the value of money. It is worth spending more on unique frames that are easy to wear and feels good and comfortable.
To choose the right filter you need to consider sample characteristics, volume, poresize and decide if the sample may require prefiltration because it is laden with particulate matter. Membrane Choices GHP Acrodiscs— Hydrophilic propylene membrane suitable
Phenex syringe filters • Rapid filtration of HPLC and GC samples prior to analysis • Particulate, PVC, and extractable-free filters • More consistent, reliable performance selection guide 1. choose filter diameter based on samPle volume Phenomenex products are
Typically, the first step in selecting a suitable filter is to choose a membrane that is chemically compatible with the sample (see table below for a full selection of mebranes). For aqueous samples, it is preferable to use a hydrophilic membrane (wwPTFE, PVDF, or Nylon) versus a
The polyethersulfone membrane offers high flow rates. Nonsterile syringe filters are excellent for HPLC applications. Each filter has a female Luer-lock inlet and a male slip Luer outlet. Ordering information: Nylon membrane filters 89041-306 are bulk packed in bags of 1000, four bags to a case.
