Syringe filters are a fast, convenient and reliable filter tool that is routinely used in laboratories. No need to replace membranes or clean filters, which eliminates the need for complex and time-consuming preparations. Widely used in pre-sample filtration, particle removal, and aseptic filtration of liquids and gases. This method is suitable for rinsing small samples before loading into HPLC and GC, and is often used in disposable syringes.

PTFE is hydrophobic and needs to be pre-wetted before being used with aqueous solvents. Used for: corrosive solvents, strong acids, alcohols, alkalis, aromatic hydrocarbons. Not suitable for: water-based samples.

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.

Aijiren Syringe Filters is a comprehensive range of non-sterile disposable syringe filters for reliable sample preparation. Reproducible membrane quality and automated manufacturing processes ensure particulates are removed from each and every sample, extending analytical column lifetime and minimising injection port or valve damage.

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).

Cellulose acetate is a very low protein binding membrane that is ideal for aqueous based samples and biological samples. It is a lower protein binder than either polyethersulphone or PVDF membranes, but has a lower chemical resistance than regenerated cellulose (RC). CA is a strong membrane mechanically and hydrophilic.

The syringe filter has the following characteristics:
1. Convenient, readily available, easy to operate, economical and practical.
2. Reliable bacteria retention efficiency ensures the filtering and sterilization effect.
3. Larger effective membrane filtration area: 1.09cm2.
4. High flow rate, high throughput, dead volume no more than 10¦Ìl.
5. Very low protein adsorption.
6. Pass HPLC dissolution test.

Compared with Nitrocellulose membrane (NC membrane), PVDF membrane has many advantages. PVDF membrane has high mechanical strength, is not easy to break or curl; it has the advantages of low background, wide solvent compatibility, and excellent coloring ability; in addition, PVDF membrane can be repeatedly tested after proper treatment.

Aijiren Tech Aijiren Syringe Filters are a comprehensive range of non-sterile disposable syringe filters for reliable sample preparation. Reproducible membrane quality and automated manufacturing processes ensure particulates are removed from each and every sample, extending analytical column lifetime and minimising injection port or valve damage.

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.

Another way to determine the micron size of columns, 0.45 um for >3 um, and 0.22 um for <3um. 0.45 um membranes are typically used for general filtration and particle removal while 0.2/0.22um membranes, or sterilizing-grade membranes, are most commonly used for solution sterilization (bacteria removal).

Aijiren manufactures a Syringe Filter that comes in a number of different membranes, PTFE membranes are hydrophilic and inert and fit many different types of agents, the details below contain the chemicals compatible with the PTFE Syringe Filter. In addition, the article number and specific specifications of Aijiren PTFE have been clearly described. If you have any needs, please leave a comment below for inquiry.

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.

The special color contrast provided on the surface of the MCE film helps to detect particles and minimize eye strain. It is ideal for the recovery and retention of bacteria in colony counting and sterility testing, as well as water/wastewater analysis and other microbiological tests.

In HPLC analysis, the particle size of the chromatographic column packing is small and easily blocked by contaminant particles. t. In HPLC analysis and IC analysis, syringe filters can be used to filter sample solutions, which is an important step in sample pretreatment.

Aijiren Tech’s syringe filters are a complete range of non-sterile disposable syringe filters for reliable sample preparation. Repeatable membrane quality and automated production processes ensure that particles are removed from each sample, extend the service life of the analytical column, and minimize damage to the inlet or valve.

Although Aijiren has attractive prices, it still focuses on quality. The membrane material of the syringe filter is provided by the most famous people in the industry, and in the ISO9000 certified production process, under the certified clean room conditions, the latest manufacturing technology is used to ensure high-quality and stable products to achieve the highest standard.

PVDF syringe filters have excellent chemical compatibility, mechanical strength and low extractability. In these filters, the maximum allowable housing pressure is 150 psi. It improves the filtering speed. These filters have high temperature resistance due to their materials. They have excellent flow rate and temperature stability.

The Sterile syringe filter produced by Aijiren is a single-use membrane-based filtration facility that is mostly used to remove particulate impurities from liquid and gas samples before analysis by HPLC, ion chromatography, gas chromatography, ICP, and dissolution testing methods. . Correctly filtering samples in chromatographic experiments can improve the quality and consistency of analysis results and reduce instrument downtime. The sterile syringe filter adopts high-temperature aseptic processing and vacuum packaging of liquid to ensure the cleanliness of the syringe filter. It is recommended to be used once.
