However, with so many options and considerations to take into account when selecting a syringe filter, it is common to have questions and concerns.
In this article, we will address 20 frequently asked questions about 0.45 syringe filters and provide comprehensive answers to help you make informed decisions about your filtration needs.Filter your sample before chromatography instrument, it can help your chromatography instrument. Aijiren lab membrane syringe filter is the best choice.

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

In chromatographic experiments, the sample is placed on the chromatographic column for analysis after the sampler is injected. However, the inner core of the sampler and the chromatographic column is relatively thin. If there are large particles in the sample, it may cause the device to block , Need to use Syringe Filter for preliminary sample filtration treatment.

Aijiren disposable MCE syringe filter units are designed to provide clear filtration of aqueous and organic solutions from small volumes up to 100 mL.

Due to the high hydrophobicity of the PVDF membrane, it needs to be immersed in ethanol, methanol or other suitable 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.

Aijiren disposable syringe filter devices are designed to provide fast and efficient filtration of aqueous and organic solutionsfrom small volumes up to 100 mL.

The PVDF Syringe Filter produced by Aijiren is made of high-quality raw materials. The filter membrane is very suitable for sample preparation and reagent filtration. Aijiren believes that the PVDF Syringe Filter can be integrated with water-based reagents, and the hydrophilicity ensures that the PVDF Syringe Filter can filter water-based reagents. success.

The syringe filter produced by Aijiren is the preferred method for filtering small samples before being loaded into HPLC and GC, and is usually used with disposable syringes to filter out impurities in the sample to ensure that there is no quality in the test Problems and affect the experimental results.

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.

Ideal for use with aqueous and organic solvents, Nylon Syringe Filters are an excellent choice for filtering high-performance liquid chromatography samples. Nylon syringe filters are durable, tear resistant and wet evenly.
PES (Polyethersulfone ) syringe filter is natural hydrophilic which makes is an ideal choice (highly recommended) for aqueous solutions and alcohols. It’s not necessary to treat the filter membrane surface with wetting agents.

Use Aijiren CA syringe filter to remove interfering substances and fine particles to the rated pore size, thereby obtaining a cleaner sample extract. Cellulose acetate (CA) syringe filters are ideal for filtering tissue culture media and filtering sensitive biological samples. Adding a syringe filtration step before chromatographic injection not only helps to ensure more consistent and reliable results, it also helps protect the instrument and extend the life of the column. Economical choice Syringe filters are available in a variety of sizes and membrane types to meet the needs of any application.

Our Syringe Filters are high quality, well packaged and sold at a fair competitive price. They are available in most of the major membrane materials including Nylon, PTFE, PES, MCE, PVDF, CA, PP, and GF which are supplied in 13mm, 25mm formats in virgin polypropylene housings.

These syringe filters feature a user-friendly design, allowing for convenient and hassle-free filtration. They are compatible with standard luer lock syringes, enabling simple attachment and detachment. The filters come pre-sterilized and individually packaged, ensuring convenience and minimizing the risk of contamination.

Aijiren’s syringe filters and vials reduce HPLC sample preparation time and the use of consumables, and the track-etched membrane is also essential for extruding liposomes for encapsulation and targeted drugs.

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.

Polyvinylidene difluoride (PVDF):?designed for high tensile strength, high solvent resistance, and low protein binding, making them suitable for biomedical filtration, sterilization filtration, and HPLC sample preparation. pH range ~1-14.

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.

Don¡¯t use with: ?Some strong acids, bases, esters, ethers or ketones.?
Sterilization: Syringe filters can be sterilized by autoclave at 125¡ã for 15 minutes.?
Applications: General biological filtration, filtration of samples for high protein recovery.?

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: 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.

PP housing membrane syringe filter refers to a syringe filter wif a housing made of polypropylene (PP).

Polypropylene is a commonly used material for syringe filter housings due to its chemical compatibility, low extractables, and resistance to a wide range of solvents. PP housings provide structural support to teh filter membrane and help maintain its integrity during filtration.
These syringe filters find applications in various fields such as pharmaceuticals, biotechnology, environmental analysis, food and beverage testing, and research laboratories where precise filtration is required to ensure sample purity and integrity.
