Medical material water resistance performance tester Sanquan Zhongshi brand
The medical material water resistance performance tester ZS-02 is a laboratory testing instrument developed by Jinan Sanquan Zhongshi Experimental Instrument Co., Ltd. with reference to the relevant standards of pharmaceutical packaging materials. It is specially used for the detection of water resistance performance indicators of medical products directly contacting wounds. The instrument can be used for laboratory testing of type products such as band-aids, bandages, medical tapes, coated papers, non-woven materials or composite materials.
Medical material water resistance performance tester
As early as 4,500 years ago, people found that wound healing was better after wound coverage. For a long time, humans have developed a large number of different types of dressings, but zui has influential, long application time, and market share is still a traditional medical gauze contact dressing. The barrier properties of medical dressings to externally applied water are especially important for wound healing. When washing hands, liquid splashing or during medical treatment, if the water blocking performance of the dressing is poor, the contaminated water will pass through the dressing. Contact with the wound, causing secondary pollution of the wound, hindering wound healing. Therefore, the water-blocking performance of the dressing is to determine whether the dressing can meet the key indicators of medical treatment.
The water-blocking performance tester for medical materials produced by Jinan Sanquan Zhongshi Experimental Instrument Co., Ltd. can complete the detection of water-blocking performance of medical dressings. The instrument is developed according to the standard YY/T 0471.3 "Test method for contact wound accessories" Part 3: Water repellency, electromagnetic control, automatic water injection and automatic timing function makes the operation more convenient. Some technical parameters of the instrument are as follows:
Hydrostatic pressure: 500mm
Switch control: solenoid valve withstand voltage time: 0 ~ 99.99
Appearance size: 500 × 200 × 750 mm (length, width and height)
Weight: 5Kg

When testing with the medical material water resistance tester, follow these steps:
1. The prepared sample should be free of wrinkles.
2. Fill the tank with purified water at (21 ± 2) °C.
3. Place the sample on the lower ring in a horizontal sliding manner to avoid air between the surface of the water and the lower surface of the sample.
4. Cover the upper surface of the specimen with a dry filter paper larger than the test area, place the upper ring, and clamp with a threaded device.
5. Inject water into the tube to the desired water level above the surface of the sample.
6. Maintain the hydrostatic pressure (300 ± 10) s.
7. Check the filter paper for water seepage through the sample and record the results.
