Filter sterilization, that is, removing microorganisms by physical means such as screening or filter material adsorption, is a commonly used method of sterilization. The filtration method is widely used, and some materials that need to be sterilized cannot be heated, such as many vitamin solutions. In addition to being used in the production of beverages and drugs, the air is often sterilized by filtration. When we usually do microbiology experiments, the sterilized container is usually plugged with cotton at the outlet, which is actually filtering to remove microorganisms in the air, so that there is no microbial contamination in the air entering the container.

Components of PTFE Syringe Filters These syringe filters usually have hydrophobic PTFE filter media and are placed in glass fiber reinforced polypropylene. In order to obtain a higher filtering effect, there are two types of outlets, one is a male Luer sliding outlet, and the other is a female Luer lock inlet.

In order to filter the particles correctly, you need to find the right size filter. You should choose the diameter of the filter carefully. They usually have sizes of 13mm, 25mm and 30mm. Each of these has a different ability to hold particles. According to the sample size, you can choose the appropriate filter diameter. For example, a diameter of 13 mm can be used for 1-10 ml samples. Similarly, 25 mm PVDF syringe filters can be used for sample volumes of 10-100 ml. Their retention is less than 100 ml.

This nylon membrane can be used for alkaline blotting and fixation, but if fixing methods such as baking and ultraviolet rays are used, higher nucleic acid detection sensitivity can be obtained. Since the nylon membrane is a hydrophilic membrane, it does not need to be immersed in ethanol, methanol and other solutions for activation. This product is only for scientific research by professionals, and must not be used for clinical diagnosis or treatment, or used for food or medicine, and must not be stored in ordinary residences. For your safety and health, please wear lab coats and disposable gloves for operation.

1. The pore size of the needle-punched membrane is accurate, providing comprehensive protection for your instrument and chromatographic column
2. There is a clear label on the Nylon syringe filter to avoid confusion
3. The luer interface of the needle filter with lock can prevent the filter from flying out due to excessive pressure

Polypropylene is compatible with acetone, ethyl acetate, methanol, isobutyl alcohol, methanol, and methyl ethyl ketone. Polypropylene is incompatible with cyclohexane, ethers, dichlorobenzene, pentanes, methylene chloride, and trichlorobenzene.

The PES film is sealed in the polymer shell without the use of any adhesive. Each unit can provide ETO or Gamma radiation disinfection, and ensure that there is no pyrogen.

Instructions for use and precautions:
1. It must be used with disposable syringes and glass syringes. The interface is standard. Put the needle filter on the syringe first, then pour the liquid into the syringe, press the push rod down, and collect the filtered liquid.
2. Do not use a syringe smaller than 10cc, because the small-volume column may cause the pressure to exceed the upper limit and cause damage to the filter membrane.
3. Only for laboratory use, one-time use, non-renewable.
4. The filtrate at the beginning of the part should be discarded. The volume is about the dead volume of the filter. Taking 25mm as an example, discard the first 1mL filtrate; or pre-clean the filter with 1 to 2mL of solution.

Adding a syringe filtration step before the sample injection not only helps to ensure more consistent and reliable results. It also helps protect delicate instruments and extend column life.

Sterile filtration is used in many applications: serum-containing or non-serum-containing media that supports the growth of cell cultures, reagents or solutions containing sensitive components that will degrade during high temperature processing, and when there is no autoclave, filtration should be added to the sterile growth media supplement Liquid, filter samples to avoid microbial growth during storage, filter buffers, remove particulate matter and avoid microbial growth during storage, filter biological samples to be analyzed, avoid microbial contamination of expensive equipment, filter environmental samples to be analyzed, filter fermentation liquids, Further purification or analysis.

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 sterile syringe filter provided by Aijiren has a cellulose acetate or PES filter membrane. A sterile membrane with a pore size of 0.2um is an ideal material for sterilization and filtration, while a pore size of 0.45¦Ìm can be used for clarification. The sterile needle filter is sterilized by gamma radiation, which avoids the toxic residue caused by other sterilization methods

PES syringe filter is mainly used for filtering and sterilizing liquid samples of small volume samples such as a small amount of buffers, protein solutions, additives, various reagents or drugs, and removing particles. It is also the first choice for sterilization and filtration of small samples of HPLC and GC. method.

Customers can use sterile syringe filters to filter out particles and contamination in the fluid. Filtration requires a 0.2¦Ìm pore size to produce a sterile filtrate. The volume of the solution to be filtered varies from a few milliliters to several liters. Typical fluids may include serum-containing media, buffers, biological or protein samples, reagents, or other fluids, and need to be free of particulates or microbial contamination.

Use a disposable filter and a disposable sterile syringe to filter and sterilize, first suck the solution to be filtered into the syringe, and then pressure the solution into the sterile container under the filter (which contains a filter membrane with a pore size of 0.22 microns) ,This is done. If the amount of solution to be filtered is large, you can purchase a filter device with a pump.

Low protein binding rate: These filters have a low protein binding rate. When the sample is less bound, its fluidity increases, and it also has better diffusion properties. Samples purified with PES filters can produce better results by tolerating slight changes in their density-related properties.
