Lvyuan 0.2 to 5 microns needle filter

A needle filter is a type of filter commonly used in medical applications to remove particles or impurities from fluids such as drugs or blood. The following are some specifications for a needle filter:

1. Pore size: Needle filters typically have pore sizes ranging from 0.2 to 5 microns, depending on the application. The pore size of the filter is selected based on the size of the particles to be removed and the desired flow rate.

   
   

2. Material: Needle filters are made from a variety of materials, including polypropylene, nylon, PTFE, and PVDF. The material used for the filter is selected based on factors such as chemical compatibility with the fluid being filtered, thermal stability, and mechanical strength.

   
   

3. Housing: The housing of the needle filter is typically made from polypropylene or another plastic material. The housing is designed to fit onto a syringe or other delivery device and to provide a seal around the filter membrane.

   
   

4. Filtration area: The filtration area of the needle filter is typically small, ranging from a few square centimeters to a few square millimeters. This allows for high filtration efficiency in a compact size.

   
   

5. Flow rate: The flow rate of the needle filter depends on the pore size, membrane material, and the viscosity of the fluid being filtered. In general, smaller pore sizes and thicker fluids will result in lower flow rates.

   
   

6. Sterilization: Needle filters are commonly sterilized using gamma radiation or ethylene oxide gas to ensure that they are free from contaminants before use.

Overall, the specifications of a needle filter will depend on the specific application and the requirements of the user.
