Application Fields And Related Descriptions Of Disposable Syringe Filters

The housing material of the syringe filter is made of sanitary polypropylene material, and the product structure is precisely designed to ensure smooth filtration, rational internal space, and a very low residual rate, thereby reducing the waste of samples.

The disposable syringe filter is a filtering tool routinely used in laboratories. It is used in HPLC sample preparation, routine QC analysis, protein precipitation removal, dissolution determination, food analysis, biofuel analysis, environmental testing.

The disposable syringe filter is a fast, convenient and reliable filter tool that is routinely used in laboratories. It has a beautiful appearance, light weight, and high cleanliness. It is mainly used for sample prefiltration, clarification and removal of particles, and sterilization and filtration of liquids and gases. It is a method for filtering small samples of HPLC and GC. According to the sterilization method, it can be divided into sterilization and non-sterilization.

disposable syringe filters

The disposable syringe filter does not need to change the membrane and clean the filter, eliminating the complicated and time-consuming preparation work, and is widely used in the laboratory. The product is mainly used for sample pre-clarification, particle removal, sterilization filtration, etc.

Among them, the syringe filter is used in conjunction with a disposable syringe. It is a fast, convenient and reliable small-volume sample filter processing device that is routinely used in laboratories. Its filter diameter is 13mm and 25mm, and the processing capacity is from 10ml to 100ml.

Syringe filters are divided into disposable and multi-use, organic or water systems, and are used for sample filtration in liquid or gas phase analysis.

Filter materials of disposable syringe filter are: Nylon, polyvinylidene fluoride (PVDF), polytetrafluoroethylene (PTFE), polyethersulfone (PES).

Advantages of syringe filters

In HPLC analysis, the particle size of the chromatographic column packing is small and it is easy to be blocked by impurity particles. So, samples and solvents need to be pre-filtered to remove particulate contaminants and protect the instrument. Ion chromatography, which is commonly used in environmental analysis, also requires that no inorganic contaminants be introduced in sample pretreatment. Syringe filters is ideal for HPLC analysis and IC analysis. Filtering sample solutions is an important step in the sample pretreatment process.

·One of the shortcomings of traditional filters is that they are easy to burst. This product is specially designed to withstand a burst pressure of up to 7bar.

·The edge of the filter is threaded to prevent slippage, and the user-friendly design makes the operator handy.

·Stable membrane quality and zero difference between batches ensure the consistency of analysis results.

·The clear specification mark avoids confusion.

The syringe filter is suitable for the filtration of a small amount of samples in the laboratory. It has low adsorption of samples, thus ensuring the maximum recovery of small or high-value samples. The filter shell is made of polypropylene, welded by ultrasonic, and does not contain sticky Mixture, so it will not contaminate the sample.
