Needle filter is a fast, convenient and reliable filter tool used in the laboratory. It is beautiful in appearance, light in weight and high in cleanliness. It is mainly used for sample pre-filtration, clarification and particle removal, liquid and gas sterilization and filtration.
Needle filters are suitable for the filtration of a small number of samples in the laboratory, it has a small sample adsorption, so as to ensure the maximum recovery of a small number of or high value samples, the filter shell is made of polypropylene, ultrasonic welding, does not contain adhesive, so does not contaminate the sample.
The advantages of needle filter:
1. the flow rate is faster
The larger filter surface area increases the flow rate and filtration volume, and also makes the filtrate easier because it reduces the pressure required to empty the syringe.
2. Higher operating pressure
Needle filters have a maximum housing pressure of 10.5bar, which means you can filter faster than ever before.
3. Color code
The colored outer bands on the housing clearly indicate the type of filter film inside.
4. reliable performance
Needle filters are manufactured in a controlled environment and in an automated process. The operator's hand should never touch the filter during assembly. The quality certificate contained in each box describes the quality standards in detail.
Needle filter is in the ordinary filter membrane before adding a layer of pre-filtration membrane, to protect the role of microporous filter membrane. The prefiltration membrane removes particulate impurities while preventing sticky impurities from clogging the filter. The filter membrane is made of chemically inert material and is resistant to most solvents. The rigid and large specific surface area structure of the membrane has the characteristics of small retention capacity and low resistance, so the needle filter can maintain high flux even when dealing with difficult to filter samples.
