Generally speaking, 0.45 ¦Ìm pore size is suitable for removing particles from samples or the mobile phase solution of chromatography equipment, and 0.22 ¦Ìm is suitable for filtering microorganisms.

Polyethersulfone (PES):?Hydrophilic, stable in low pH, have low levels of extractables, and exhibit low protein binding, making them suitable for many aqueous and organic solvents. PES membranes allow higher liquid flow than PTFE. Temperature resistant. pH range ~3-14 (sometimes quoted as 1-14).

PTFE Syringe Filters consist of a polytetrafluoroethylene (PTFE) membrane and a polypropylene overmolded housing. Available in 13 mm and 25 mm diameters and 0.22 μm and 0.45 μm pore sizes. PTFE is the membrane of choice for use with aggressive solvents, liquids, and gases that can attack other membranes.

Syringe filter is a disposable device used in laboratory settings to filter small volumes of liquid samples. It is commonly utilized to remove particulate matter and microorganisms from solutions before analysis or to protect sensitive instruments from contamination.
Syringe filters consist of a plastic housing with a membrane filter at one end and a female luer lock or luer slip connection at the other end. The filter membrane is typically made of materials such as nylon, polyethersulfone (PES), polytetrafluoroethylene (PTFE), or cellulose acetate.

In the sample application of choosing the appropriate syringe filter and syringe, draw your sample into the syringe and place the filter on the syringe. If you are using a leur lock filter, make sure you have properly secured the filter into the syringe tip .Push a few drops through the filter with the syringe filter facing up and “top”. Place the filter in the overturned collection container and push the sample through the syringe filter by applying gentle positive pressure. The syringe filter to be cleared and the maximum To maximize sample throughput, remove the filter from the syringe and draw air into the syringe. Then reinstall the filter and push the plunger to force some air through the filter.

13mm, 25mm 0.22um, 0.45um hydrophobic PVDF (polyvinylidene fluoride) membrane syringe filter is a filtration device commonly used in laboratory settings to remove particulates and microorganisms from fluids.
It’s important to note that specific details of hydrophobic PVDF membrane syringe filters, such as pore size, diameter, and filtration capacity, can vary between manufacturers and product lines.
Therefore, it’s recommended to consult the product specifications or contact the supplier for precise information about the syringe filters you are considering for your specific application.

PES syringe filter membrane has the characteristics of high mechanical strength, it can handle high temperature liquid, and has a large flow rate (better than PTFE), and low protein binding force. With these functions, PES syringe filters can provide excellent performance for biological samples and culture media. The usable pH range is about 3-14.

By using Aijiren syringe filters unwanted particles are removed which can otherwise cause contamination and clogging of sensitive instrumentation. So, filtering your samples leads to an increase of lifetime and less downtime of chromatographic columns and equipment, gives more consistent and reproducible results and thereby saves time and money.

The Non-sterile Disposable Syringe Filter is a versatile filtration device used in laboratories for sample preparation and clarification. It consists of a polypropylene housing with a membrane filter, providing efficient filtration of particulate matter and microorganisms. These syringe filters are available in various pore sizes and diameters to suit different filtration needs, and they come in non-sterile packaging.

Aijiren¡¯s PP syringe filter uses a hydrophobic polypropylene membrane, which has stable physical and chemical properties, good compatibility, low protein adsorption, and is suitable for filtration of aqueous solutions and most solvents. Commonly used to filter biological samples, solvents, deionized water and reduce biological load, the hydrophobic PP filter membrane is particularly good for gas filtration. The product was sterilized by dry heat at 121¡ãC for 15 minutes.

PTFE: is perfect for the filtration of gaseous or organic solvent-based samples and highly corrosive substances. Hydrophobic so provides chemical resistance to aggressive media and excellent temperature stability allowing an extended sampling range. If used with aqueous samples, the membrane usually requires pre-wetting (normally by using a small amount of alcohol). Can also be used to prevent moisture passing through air vents. pH range ~1-14.

Among the many medium types of Syringe Filters produced by Aijiren, Polypropylene Syringe Filter is a special one. Because Polypropylene is often used to make the shell of Syringe Filter, there are fewer types of membranes made of Polypropylene. Aijiren finally decided to use this material to produce Syringe Filter after studying the production materials of many different manufacturers and the usage of different customers.

Aijiren disposable PVDF syringe filter devices are designed to provide clear filterate of aqueous and organic solutionsfrom small volumes up to 100 mL.
PVDF syringe filters are made of hydrophilic PVDF membrane and a polypropylene overmold housing.

Hydrophobic PTFE (Polytetrafluoroethylene) syringe filters are suitable for gaseous and organic solutions, with excellent performance for high corrosive samples.
