Negative pressure tester for medical syringes

Product introduction

　　The positive pressure tester for syringe cohesion is composed of intelligent manipulator, 

force measuring mechanism, distance measuring group mechanism, printer and so on. 

Among them, the intelligent driver is composed of CPU, motherboard, LCD display screen, 

keyboard, power supply and other parts. Implement GB ****0 standard requirements, 

positive pressure test principle, check the syringe's tight fitting performance.

Reference standard

　　GB/T *********1 "Disposable sterile syringe", YY/T ********3.

Test principle

　　The syringe is sucked into the nominal capacity of water, with the specified axial pressure 

and lateral force, the effect on the core rod is *0s, and the part of the jacket and the piston 

shall not have leakage phenomenon. Under the effect of *8KPa negative pressure, adhere to 

*0s±5s, the contact part of the jacket and the piston shall not produce air leakage, and the 

piston and the core rod shall not be separated.

Technical parameters

　　1. Lateral force: 0.*5 — 3.*0N, error is not more than ±0.5%

　　2. Axial pressure: **0 — **0kPa, error is not more than ±2%

　　3. Nominal capacity: 1 — **0ml, optional

　　4. Test time: 0 — ***9 seconds, arbitrary setting

　　5. Working temperature: 5 — *0℃

　　6. Relative humidity: （*5 — *0） %
