**YS-SLN-10 Infusion Set Leak Negative Pressure Tester**
**【Scope of Application】**
The infusion set leak negative pressure tester is suitable for seal leakage testing of single‑use sterile infusion
sets. By testing the sealing performance of infusion sets, it is an ideal testing instrument for medical device
manufacturers and is widely used in various testing institutions.
**Test Principle:** Fill the infusion set sample with degassed distilled water, connect it to the vacuum test port
of the instrument, block the other outlets, place it in a 40°C water bath, and apply a negative pressure of –20 kPa
for 15 seconds to check whether air enters the infusion set.
**【Applicable Standards】**
GB 8368‑2018 “Infusion sets for single use — Gravity feed type”
**【Instrument Features】**
1. Intelligent embedded operating system with a user‑friendly interface — what you see is what you get.
2. 5‑inch color LCD screen with high‑definition display.
3. High‑quality metal buttons for start and stop, making operation more convenient and faster.
4. Preset test vacuum level and holding time ensure accurate test data.
