Third generation detachable coaxial needle

 

Jet spinning needle1722:

 

The difference between the third generation detachable coaxial needle and the second generation detachable coaxial needle:

1、The third generation has no welding wire and the second generation has welding wire,The former has smooth wall,The latter has thread on the wall,How much will affect the liquid flow field。

2、The third generation of threaded connections can withstand high pressure,The second plug seal cannot withstand high pressure,For the experiment with high viscosity or high velocity,The third generation is more suitable。

3、In the third generation, the outer needle can be changed to other sizes with the same inner needle,So as to match different types of coaxial needles,The second generation models cannot be replaced。

4、The third generation is threaded connection,The distance between the inner and outer needles cannot be adjusted,The second generation can adjust the distance between the inner and outer needles by pulling out and inserting the inner needle

Second generation detachable coaxial needle

 

15-21GThe dimensions are as follows:Inner diameter of inner tube0.5external diameter0.8;Inner diameter of outer tube1.45external diameter1.81。If the system contains nanoparticles,Or solvent with strong volatility and high viscosity,This needle is recommended

17-22GThe dimensions are as follows:Inner diameter of inner tube0.34external diameter0.63;Inner diameter of outer tube1.12external diameter1.48。It is recommended that nano particles should be contained in the system or submicron spinning should be prepared、Medium volatile and viscous、The solution is not easy to block、Taylor cone is difficult to form in electrospinning experiment

18-25Gas follows:It is recommended for the preparation of nanograde or submicron grade fibers or particles。Use a general volatile solution。
