Premium HPLC Syringe Filters 0.22µm & 0.45µm | Lab Filtration

Syringe Filters with hydrophobic PTFE membranes can be used for filtration of strong solvents, acids and alkalis. Not suitable for filtration of aqueous liquids. Filters with hydrophilic PTFE can be used for filtration of strong solvents, acids and alkalis. However, these syringe filters can also be used for the filtration of aqueous liquids, which makes this type very versatile.

Aijiren syringe filter membrane use method introduction: before inhaling the sample, suck about 1ml of air into the syringe, so as to minimize the liquid residue, suck the sample into the syringe, invert the syringe and clear all the residues on the top Clean, connect the needle filter to the syringe, tighten it gently to ensure a good seal, filter the sample in the syringe and inject it into the sample bottle, and then follow the steps to maximize the recovery rate, remove the filter, and suck air into the syringe, Reconnect the filter head and eject all residual samples.

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.

Compressed sterile air filters can be used to create clean rooms free of bacteria and other harmful particles for people with compromised immune systems. Each air supply pump is also equipped with a sterile air filter to ensure the delivery of pollution-free air. These air filters are usually sterilized by gamma rays and packaged separately.

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

Syringe filter is a quick, convenient and reliable filter tool used routinely in the laboratory.Because they don’t need to change the membrane and filter cleaning, it’s eliminating the complex and time-consuming preparation. It is widely used in the sample pre filtration, removal of particles, aseptic filtration of liquids and gases. It is the preferred method to filter small samples before loading into HPLC and GC ,and it is often used with disposable syringe.

PTFE syringe filters are made of Polytetrafluoroethylene (PTFE) membrane and a polypropylene overmold housing.

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.

The EPA VOA vials feature a secure closure mechanism to maintain sample integrity and prevent sample leakage or contamination. The vials typically come with a screw cap equipped with a septum, ensuring a tight and leak-proof seal. This closure mechanism ensures the preservation of volatile organic compounds during storage and transportation.

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.
