The technical requirements of the horse paste dispensing syringe

Today the paste syringe is used more and more,it is popular in the world.But many people don't know this syringe,so today I will introduce the technical requirements of the paste syringe according our factory standard.

Our factory is a professional horse paste dispensing syringe manufacturer,we have our syringe standard,and I will introduce the technical requirements from two aspects,one is sensory requirements,the other one is physical and chemical indicators.

First I will tell the sensory requirement.

  1. Appearance,in natural light bright place,the syringe should have uniform colors,the surface should bright and clean,smooth,don't have obvious chromatic aberration.

  2. The barrel of syringe is not crooked,the syringe don't have rags,deformation,cracks,sand hole,oil contamination,bubble;

  3. the inside wall of barrel should be smoothness,don't have crinkle.

  4. the syringe tip should be smooth

  5. the syringe don't have defective printing which can influence of using

Second,I will introduce the physical and chemical indicators.

  1. the pullout force of the tip cap,the pullout force of the tip cap should be among 4.0-4.5N

  2. Cooperation of plunger and piston,after the piston is lubricated by silicone oil,insert the piston into the syringe and lid the tip cap,pull the plunger 3mm,the plunger must keep stable and don't separate from the piston

  3. Leakproofness:applied 30N axial force on the plunger and keep 30 minutes,then observe the syringe,the tip cap seal and the piston seal should not have leak

  4. Unctuosity:insert the plunger and piston into the barrel of syringe,the plunger piston should move smoothly without sudden pause.

  5. Anti-drop: Drop the syringe from height of 1.5 meters to a horizontal rigid smooth surface,the syringe don't fracture

  6. Residual amount: The residual amount should not exceed 3% of the indicated capacity.

  7. Residual ethylene oxide: no more than 1 μg / ml.

  8. PH value: the difference between the test liquid and the blank liquid does not exceed 1.0

  9. UV absorbance: the maximum absorbance between wavelengths must not exceed 0.10

  10. Easy oxide: the titration solution which is consumed by the test liquid and blank liquid,the difference between the two must not exceed 1.5ml

  11. Non-volatiles: the difference between the non-volatile residue and its blank residue must not exceed 12.5mg

  12. Heavy metals: The amount of metal should not exceed one part per million.
