Nylon 66 with a pore size of 0.45

Has broad chemical compatibility and stability. Alkali resistant but not strong acid resistant. Has good mechanical strength and heat resistance. Has good flexibility. Can tolerate most organic solvents and most alkaline solutions.

Suitable for water filtration in the electronics, microelectronics, and semiconductor industries; Chemical product organization culture medium. Filtration, liquid clarification, sterilization, and particle filtration of medicinal liquids, beverages, and high-purity chemicals.

Nylon filter membrane has a very pure texture and good hydrophilicity. The solvent extractable level is extremely low, and it has high mechanical strength, which can be applied in many fields. Nylon filter membranes undergo extensive testing before packaging to ensure that the extractable levels are qualified.

Select high-quality nylon 66 filter membrane imported from the UK to ensure the performance of disposable needle filters.

UK imported filter membrane pore size

0.22 μ m pore size filter membrane: recommended for chromatography systems using fillers smaller than 3 μ m or those involving microbial growth. Meet the requirements for removing extremely fine particles from samples and mobile phases.

0.45 μ m pore size filter membrane: For chromatographic column systems using 3 μ m or larger particle fillers, a 0.45 μ m pore size needle filter or microporous filter membrane can be used. Used for routine samples, mobile phase filtration, able to meet general chromatographic requirements.

Pore size 1-5 μ m filter membrane: For difficult to handle turbid solutions, a 1-5 μ m filter membrane can be used for pre filtration first, and then the corresponding filter membrane can be used for subsequent filtration. The company's quality commitment

All filters are manufactured strictly according to high-quality production processes. This ensures consistent * performance, reliability, and membrane integrity.

In addition, samples are taken from all batches of filters and filter membranes and kept for 2 years for future reference. In this way, as long as you submit an application, we can test your current batch in our laboratory according to your usage conditions and provide you with the basic parameters of the relevant batch.

In high-performance liquid chromatography experiments, sample filtration is crucial. The needle filter produced represents a new standard for high-quality sample preparation, which can give you full confidence in the filtration effect.

Raw materials and production technology support

The filter is made of an inert pure polypropylene shell without extractables and a screw lock fastener. Each filter is sealed with a locking ring, achieving universality and maximum operational safety. This process further enhances the strength of the filter, which is conducive to preventing dangerous explosions. The filter does not use any adhesive throughout the body, thus avoiding contamination of the sample, which is crucial for maintaining the integrity of the sample. At the same time, the specialized technology of the internal flow channel has increased the available filter surface.

color coded

All filters have color coding to help identify the filter membrane. And when customers require it, the filter membrane model and porosity can be printed on each filter to ensure that you use the correct filter membrane.

The specifications of the filter and the filter membrane meet your sample requirements

Filters come in different specifications and are equipped with different filter membranes to meet the requirements of your samples. The following table lists typical filtration volumes. But the specific filtration capacity depends on the number of particles in the sample.
